K8N Neo4 (ms-7125 ver:1) suddenly won't boot

please help
my board just won't boot
i've removed everything except those necessary parts to boot it(proc,mem & vc)
i just noticed that everytime i switch on the avr, the fans of the proc & vc spins.
the board won't shut-off even after pressing the power button for about 10 secs
i've already tried other mems, psu, and vc
i have cleared the cmos(press the small red button to clear cmos), removed battery but still won't boot
TIA
forgot to post specs
proc: opteron 165
mem: 1x1gig corsair valuemem and 1x1gig team
psu: corsair hx620
vc: gf 6600/gf5500

you are not telling us what you were last doing before it went wrong, believe me that might give some clue, however
do you have the speakers connected to pc or not, if you do and if there is something wrong then you should hear series of beeps and by looking at the motherboard manual you might identify the prob, . you also say you pressed the red button but you are suppose to hold it for a while. try to hold it for at least ten second.
MSI does suggest unplug the pc, disconnect all power cables from PSU to the motherboard with no exception, then remove the memory, graphic card, and cpu, clear CMOs and hold it at least ten second (pref 20 sec). test those item on another pc if you can, reinstall, . if still prob, try the safe mode by pressing F8 then try VGA mode. you might have corrupted driver for the graphic card. five things can go wrong psu, cpu motherboard, memory, and HDD. by pressing f8 if safe mode appears then you have a reasonably good system the prob is window on HDD, try another HDD with a fresh window. keep cool and good luck

K8N Neo4 (MS-7125) USB, Mic, S/P Out, and LAN ports all non-functional

I'm hoping someone can give me a hand with this. I'm not a novice when it comes to motherboards but this particular board is making me feel like it.
Ok, I've got a K8N-Neo4 MS-7125 model. Athlon64 3700. I have all the current drivers and ran the liveupdate to make sure.
The LAN port will light up, but the Device manager will not recognize it, nor will the LAN utility.
The board has 4 USB ports. The top two are non-functional, the bottom two work.
The S\P OUT port has never worked, nor do I know how to engage it or find it on the device manager
The microphone....this one is fun. Its like the microphone is stuck in a feedback loop. Whatever comes through my speakers, is heard on the other end by other users. I am not heard at all, although I can hear myself through my OWN speakers. Even with the mic unplugged, people still can hear my speakers. Imagine having your speakers plugged into the mic jack. The only way to kill the feedback is to actually go into the sound manager and mute the whole mic system.
I can live without the LAN and USB ports, but it would be a HUGE help if someone can help me with the mic and S\P ports!!
Thanks!!!

Ok, I'll do my best to remember everything

As for the flavor of the NEO4 the only other numbers I know of, is on the board it says N1996 right below the processor. Is that what you need? Its a PCB V.3 board nvidia Nforce4.
Speakers are standard cyber acoustic
Logitech Mic/Headset combo
This particular case allows for hookups for headphones and mic in the front. The case has jumpers in the back that allow you to gain access from the front (but you probably already know that). I've always used the front MIC/Headset jack, and I have a splitter in the back for the headphones and that jumper. In trying to resolve the issue, I tried every jack with the microphone (even the ones that I know are labeled as speakers). I do get my own voice through MY speakers on the front jack AND the mobo jack.
Hopefully I got you enough info!
Thanks in advance!!!

Can't Boot from CD still K8N Neo4 MS-7125

I made several boot CDs, but am unable to boot from them. I don't have a floppy. I want to flash my bios. I tried to read every post related to my problem but could not find a match exactly so that's why I'm posting.
The error says
EMM 386 Address line A20 already enabled.
The other posts say to simply set the Gate A20 option to FAST. I went through my Bios settings several times and don't have any kind of Gate A20 option to set.
Win Xp tells me my Bios is v1.0 but my Bios says my Bios is 1.5 and I'm trying to Flash to v 1.8.
I've tried everything I could think of.

I don't have access to the Internet on my computer, I'm typing this on my friends computer. I found a way to get around the problem though temporarily until I can figure out a way to create a bootable
CD.
My work around was this. I created several boot CDs from several different software programs, none of them worked. I tried Ultimate Boot CD UBCD. and there was an option called go to Dos level using Madboot. I went to DOS level and tried running the flash utility on my C: drive but it came back with the message ' unknown file or program'. Then I tried putting in a CD into the CDrom drive that I burned earlier with the files for flashing the BIOS and ran them from there. Why didn't they run on my C: drive and only on my CDrom drive? I don't know, but it worked.
Thanks

OS-X suddenly won't boot

OS-X suddenly won't boot on a G3 desktop w/ 4.0 Gb hard drive with ~380 Mb free space. The boot screen comes up and the "pinwheel" spins forever. I ran Disk First Aid from the OS-X Install disk, and Verify reports the following errors:
Missing thread record (id=10180)
Invalid sibling link
Repair reports the same errors and runs to completion, but doesn't fix the problem. I've run Repair several times with same results.
Just before all this, Safari wouldn't launch. Shut the machine down to reboot and now this.
Anyone have any ideas? Thanks in advance!

OK, so I went out and bought Disk Warrior. The machine will NOT boot from the CD. When I start up holding the C key down, it seems to try booting system 9 off the hard drive, but then it goes into an endless cycle of reboots. Continuing to hold the C key down simply causes repeated reboots; it never gets beyond the Happy Mac icon.
I have also tried holding OPT-CMD-SHIFT-DELETE, but I just get the floppy icon with the flashing question mark. If I release those keys, it attempts and fails to boot 9 off the HD, then tries X and hangs as described in my first post.
The machine WILL read an OS-X Install CD (actually, several) and WILL boot up normally from a System 9 Install CD. So the CD-ROM drive appears to be OK.
I've loaded the Disk Warrior CD into another machine and it looks fine.
I'm completely stuck. Any thoughts? Thanks again in advance.

K8N Neo4 (MS-7125) northbridge fan replacement?

Hello, all. I have started to build a new system using the K8N Neo4 Ultra (MS-7125) mobo. When installing the mobo yesterday, I noticed for the first time that two of the fan blades for the northbridge had broken off. They were not in the anti-static bag and this was the first time I had the board out. I ordered this on May 25, so I can't return it.
Would it be a good idea to replace the fan?
Any suggestions on what to use for a replacement?
Will I need to take the mobo back out of the case to replace the fan?
Thanks much.

Should still be under warranty from MSI so you should be able to RMA the board by contacting them

IBook G4 suddenly won't boot past the "booting OSX" screen.

My iBook G4 suddenly died and now won't boot past the "Starting OSX" screen. The blue bar goes all the way across but never moves to the next screen. I have my original disks, containing OS 10.4.5. I am trying to boot from the disk, but just keep getting the Installer program. When I try to choose a startup disk, it still won't start. Any help or ideas? This is urgent.
BTW, I am a photographer and was workig in PhotoShop7 -- a program I use all day, every day.

Start from the install disc again and choose Disk Utility from the menu. Highlight the drive on the left and click Repair Disk. If it reports errors and repairs made, repeat the process until no errors are reported.

K8N Neo4 Platinum 7125 not posting after overclock testing okay

Hi Guys,
I'm having a real stinker of a problem with my 7125 board. I have all good components, but can't seem to get this bastard to post reliably when I'm overclocking. I was thinking that it was my power supply so I bought a new Antec Neo3 650W supply and it doesn't matter. I also got a new Opteron 165 processor and it still has problems. I even RMA'd my board and then sent me a new one. Here is my setup.
7125 ver1
Opty 165
Crucial PC3200 Ballistix
Nvidia PCIE Gforce 6200 video
Antec Neo3 650W
2x Seagate SATA 80gig (matched) 7200.9
RAID 0 via the SIL 3114
extra 160 gig HD (using the Nvidia SATA port)
Pioneer DVD 109 DVDRW - pri IDE
Sony DRU-820A DVDRW - sec IDE
Hauppauge PVR150
3.5" card reader (connected via internal usb header)
Lian Li case
When I run the system at stock speeds everything works fine, including the initial posts.
However, when I overclock, everything is erratic. Sometimes, I can overclock the entire system to 290x3, 166, stable memory settings, and prime 95 orthos the out of it for days on end (max CPU at 49C), but when I select restart in windows, it shuts down fine, but will subsequently not post. I have to hit the reset key several times, then it recovers itself and undoes the overclocks.
I have tried all sorts of memory timings from the crucial info - it recommends 2.8V and 2-2-2-8 timings.
I have heard that my memory is good for overclocking, but I'm now starting to wonder if it is the MSI Neo4 board or the Nvidia Nforce 4 ultra chipset.
Could it be the Raid 0 on the Sil 3114? I haven't messed with this as I would rather have a RAID 0 setup, then a little overclock.
Is there a good NF4 ultra board out there that is better than this?
I can't imagine anything else to do except keep spending more money to eliminate more variables.
Your thoughts? Thx Nick

relax your CPU HTT freq. by 10-20Mhz and retest.
relax your memory timings e.g. from 2-2-2-8 to 2.5-3-3-8, to findout from where its comes then find optimal settings.

MSI K8N Neo-4 Platinum (7125) 1.4 BIOS Won't Boot WinXP

1.4 is a buggy BIOS! My computer restarts while loading Windows XP with this new BIOS! CAn't believe they released this crap! I'm going to attempt to use the 1.41 beta BIOS otherwise I'm reverting back to the last BIOS
Update: Tried 1.40, 1.41, and 1.52 with no success - reverting to 1.3 (hope this works otherwise a repair install probably won't do the trick)
Update: Now my computer is only detecting 768MB's of my 1GB of RAM, before I updated to 1.4 from 1.3 everything was fine. I just downgraded to 1.2 and my computer is still only detecting 768MB. I've tested both modules alone and they are detected as 524MB's each. I also tried switching to single channel mode and it is still showing up as 768MB's out of my 1GB. This is driving me nuts!
I am now going to attempt to try 1.4 and 1.52 beta again. Please help if you can?

Perpetual Laggy System Performance (K8N NEO4 PLATINUM) 7125

I was playing COUNTER STRIKE the other day and all the sudden the comp restarted but failed to reboot completely, meaning no post, no nothing but HD light on constant. I started removing all devices from IDE/SATA/PCI slots to see if it would reboot...no dice. I gave it a few more tries and still no luck. I had to leave so when I came back, I went to troubleshooting again. I plugged in only my crappy low end GF4 card and IDE drives to see if it would and it did I looked through my BIOS to see if anything has faultered, since nothing was changed I decided to plug my SATA drives in and blam again no boot/post. I then reset the CMOS settings and wala it worked! went to change the settings and then XP wouldn't boot up from my SATA drive. I decided to just reinstall everything because I like to start off fresh from fatal crashes. XP finished installing and still it wouldn't boot from SATA drive. I installed all necessary SCSI/RAID drivers, yes I know it's SATA but it goes under the category of SCSI during initial XP install. I decided to repartition/reformat/reinstall and finally it booted off the SATA drive. after this nonsense was through I thought all was smooth sailing. little did I know I started encountering an annoying enormous speed decrease, every program I tried to load would take 20-50 secs (sometimes longer) to load. so I thought what the hell, I should prolly flash the BIOS. I then flashed to 1.6 and still no dice. I then went through flashing all the 1.7's and still had the same daym problem. all drivers that I installed are the most recent. I'm now perplexed what to do from here? has anyone else encountered this problem?
I also have another question, what are average temps for everyone's CPU with the stock AMD HSF?

ok I had to speak too soon. I'm now encountering the daym load lag again but it's not as consistent as it was before. the PSU I tested again today is a FORTRON 530W the specs are as noted... +3.3V@30/17A,+5V@44/24A,[email protected],+12V@16/28A,[email protected],+5VSB@2A. he wouldn't bring his RAM over since he's afraid it'll somehow it up and past it's RMA warranty, it's understandable though. do yall think increasing RAM voltage might possibly alleviate the issue? it's currently set at 2.65 stock. I can test PSU for figures but I don't know how to do so without load unless both the 20 pin and 4 pin connectors can be left out to test? sorry for the vulgarity but I'm starting to get frustrated as all hell.

K8N Neo4 (ms-7125 v1) PCI Express Mystery

2 gig DDR dual channel ram
ATI ALL-in-Wonder 2006 PCI-E
1 sata wd 200gig (boot drive)
1 ide wd 160gig
dvd player
dvd burner
I had posted before on this subject, but I'm thinking I was off on the wrong tangent.
To recap. In the middle of the boot process (Windows XP banner displaying) video went dark and bios "no video detected" alarm went off. After this I could occasionally get the machine to start, usually after a reset. Sometimes it would work fine, other times I would get lockups. I thought the video card was bad. Bought a new, identical card. Same problem. I had recently flashed the bios (maybe a week before), I thought that may be to blame. I rolled back to the previous version, made no difference.
If I remove the PCI-E video card and put an old PCI card in, the machine is back to its old rock solid self.
It is looking to me like there is something wrong with the PCI-E bus. The power supply is an Antec 450W "Smart Power". It has two 12 volt rails, that output 15 and 17 watts. This machine had been rock solid (1.5 years) up to this point, so I doubt it was underpowered. One thing that does trouble me a bit is the fact that when I remove the AC from the power supply it emits a strange noise ( a weird hiss) maybe 4 seconds after I remove the power cord. Maybe it always did this, I don't know. In my imagination I can see a leaking cap that is boiling off electrolyte. Speaking of caps, I closely inspected all the caps on the motherboard and none of them seem to be bloated or leaking.
I tried another power supply. A single rail (20 pin) 350w Sparkle. The video behaved the same (pci-e not detected by bios). I'm not so sure this proves anything because with the Sparkle the system may be underpowered.
Where do I go from here? Did anyone ever hear of the PCI-E circuitry craping out and everything else continues to work?? Could it be the power supply?? I would think if something was wrong with one of the 12 volt rails it would affect both. I would hate to drop $90 on another power supply and find out it doesn't make any difference.
HELP.

The bios alarm is the one long two short, my board manual says that means video card not initialized. The pci-e card was in tight and locked down. Like I said above, I tried a brand new version of the same card, same problem. Since the all-in-wonder 2006 worked for a year and a half without problems, I'm thinking it is not a compatability problem.
I'm now running with a pci card and the system is it's old solid self again. If I look in device manager all the pci-e devices report they are functioning normally. Anybody know of a pci-e bus torture test ??
I've been doing a lot of reading on power supplies. Seems like Antec does not have the quality it used to. Again, I hate to drop the cash for a new ps if that is not the problem. A good one is not cheap. If I am sure the ps is the problem I will go for it. I'm still not sure it isn't a failure on the board itself.

K8N Neo4 Platinum 7125 - Switching from Single to Dual Opti - Startup Issues

My problem is the following:
I switched from Winchester 3200 single core to Dual Opteron 170.
The BIOS indicates it reading the both cores with the ACPI lingo.
I did patch the driver according to AMD with their specified download.
Now, when I start up the computer, I have to restart several times to get it to run but it does run although later locks up either when not in use or after an hour or so of gaming (mech warrior mercs) ???
I have checked the power supply voltages and they are as indicated in my profile, but I am wondering if the power
supply is not the problem. I know opterons' require a little more umph than normal single cores and this one is 4 years
old.
What do you folks think?
I would really hate to reinstall windows if it just a power supply issue.
Thanks in advance for you advise.

Reinstalling the operating system seems like awful lot of work if its the power supply.
But I appreciate the advice.
This rig is about 3 years old. I will probably wait until I have some time to do this.
What drivers do you think I need to get the USB function again for now?
Thanks.

"Reinstalling the operating system seems like awful lot of work if its the power supply."
Get a decent PSU and re-test 1st, here can be found good PSU suggestions.

"What drivers do you think I need to get the USB function again for now?"
Just delete them from device manager, then windows should detect and install them automatically.

Suddenly won't boot, start up commands not working... am I out of luck?

Funny, this is my first mac being a hardcore and longtime PC user as my "test" mac... everything works perfectly... of course until 12 days after my warranty is up...
This morning on waking up my mac to turn on some music in iTunes, i click on the iTunes window to bring it into focus. It suddenly closes and dissapears, on returning to the shortcut bar (the tray at the bottom for programs, i don't know what mac users call it) and click on iTunes ot relaunch it after its crash/dissapearance, the task tray then decides to suddenly dissapear/crash (don't know which, it's like a crash but best described as a vanishing act as it doesn't lag or churn before dying, just vanishes).
Possibly related to this issue, not long ago my iChat stopped working, whenever i launched it, it would stay open for a couple seconds and automatically closed. I could sit there all day clicking it, it would open, 2 seconds later, close. I gave up on that. I gave up on that a week ago.
Shortly after my iTunes dissapeared/crash and then after the program tray also dissapearing. my mac mini reboots. Except it's stuck on the screen with the mac apple in the middle of the screen with the moving (yes it's moving) pinwheel on the bottom center of the screen. I let it sit there for a long while... 15 minutes pass nothing happens.
I try rebooting... same thing happens.
I'm go on my PC (Which i'm now typing from) and start searching for solutions. apple support pages suggest I try safe mode with shift.
SAFE MODE: Won't work. I tried pushing both shift buttons on my keyboard at different times (before the start up tone, immediately after the beggining of the start up tone, and after the start up tone finishes) all that happens is, I get the same pinwheel/apple screen that is "loading" (according to the pinwheel) forever.
I went to forums, read up on other different commands like holding down "X" or option command P+R.... X does the same as the not-working safe mode... option command P+R continually reboots the computer.
And in the end I'm still at square one. thouroughly frustrated. wishing my mac mini was a PC (as i've never had a PC problem I can't fix) Ironic experience... PCs, break often, easily fixed, no support needed.... Macs: rarely break, when they do, support needed, but support from apple expires 12 days ago, not easily fixed... and now I think i'm screwed out of the 700$+ i payed for this POS and I've lost my whole iTunes library, all the CDs i've loaded onto it, and all the music and TV shows i've purchased from the apple music store. Good game, apple takes a bunch of money, refuses to support my product which is now dead (had a similar situation with an iPod I had bought for my girlfriend).
My only hope is... I know mac users have a happy helpful community and always band together to help fellow mac users, something the PC world doesn't as-cohsively have. So...
Help me Obi-Wan Kenobi... you guys are my last and only hope.
Thanks in advance.

Hi, John. Welcome to the Discussions.
1. You wrote: "I get the same pinwheel/apple screen that is "loading" (according to the pinwheel) forever"The "pinwheel" is known as a "spinning gear progress indicator."
This, combined with the other issues you've reported, sounds like problems with the hard drive. I suggest you begin troubleshooting using the Procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
2. You wrote: "...the shortcut bar (the tray at the bottom for programs, i don't know what mac users call it)"It's called the Dock. See "Mac OS X: About the Dock."
3. You wrote: "...this is my first mac..."My "Learning About Mac OS X" FAQ has a number of resources that you will find helpful including books, online training, and more.
4. You wrote: "...Macs: rarely break, when they do, support needed, but support from apple expires 12 days ago, not easily fixed..."You should have bought the AppleCare Protection Plan (ACPP) before your warranty expired. The ACPP provides a two-year extension on the warranty and three years of telephone support.
PS: Word to the Wise: watch the language. I appreciate your frustration, but don't let it into your posts. These forums are "family friendly" and a good way to get banned from them is to rant, use profanity (including profane abbreviations), etc. What passes for "acceptable behavior" on most PC/Windows forums is not tolerated here.
Good luck!

HELP! CD player suddenly won't boot any startup disk.

Help! I am being swamped with problems stemming from my attempt to upgrade to OS X. Can anyone help me plug the holes in my boat? I am including as much info as I can because I notice that requests like mine often generate a lot of questions about basic things. So, here it goes ... and thanks for your thoughts, Ed T. in Newburyport, MA. OK to send ideas to me [email protected]
Goal: install OX 10.3.5 (Panther) on my Mac G4 Ethernet Gigabit machine by booting from the CD install disk. I am using a full retail version (black with silver “X” v 10.3.5).
Problem: neither internal CD-Rom not external Fire Wire CD-ROM player/recorder will boot from 9.1 or 9.2 startup disks. These disks (DiskWarrior and Apple OS X insdatll disk #1) booted OK until I made upgrade preparations to get G4 and OS 9.2.2.
About two weeks ago I installed ViaVoice v2.01 Enhanced Edition and did a practice reading. I just mention this in case it might be relevant.
After installing the second HD I moved all of the document files off the original HD to the new one. I left all the applications on the original HD. I ran DiskWarrior and rebuilt the desktop for each drive. I check for fragmentation and optimized the disks which ran smoothly.
Hardware: G4 Ethernet Gigabit CPU (purchased new 2001 with RAM upgraded to 256 Mb and with an internal CD-ROM player) which uses the original processor, Que Fire external CD recorder/player connected via Firewire, Airport card upgrade and white domed Airport Hub, older HP 55M laser printer connected with an Assante Bridge unit, a cable internet box (Motorola) connected to the Airport unit. Monitor (an older SONY Multiscan 100ES purchased at SeaMUG swap meet). USB 4 jack hub (Netgear Dual Speed DS104). New external hard drive (an OWC Mercury Ultra AL 250 Gb USB/Fire Wire) connected via Fire Wire cable.
Upgrade preparations - I added some new items:
1.) I increased the original 256 RAM by installing (adding) two 512 cards from Other World Computing (OWC at MacSales.com), and ...
2.) a new ATA internal 80 Gb Hitachi hard drive (also from OWC) fitted onto the “sled” atop the original 40 Gb HD. NOTE: both drives are format extended (HFS+).
Next, I backed up original 40 Gb hard drive to my new OWC Mercury 250 Gb external HD using Retrospect.
Software: I did the following activities according upgrade decision lists from MacFixit and Apple Support Discussion Group. I did the following:
1.) Updated OS 9.2.2 firmware to v4.2.8 which I downloaded from Apple,
NOTE: this procedure involved holding in the programmer’s button (the little recessed one below the big startup button and to the right of the little reboot button) and then pressing the startup button until I heard a long tone. I released the programmer’s button and the firmware update completed successfully.
2.) I did not check for external Hard Drive firmware updates because drive is one month old, but I did disconnect the Firewire cable during the following activities,
3.) I have no “haxies” to update,
4.) There was no Stuffit Deluxe software to de-activate,
5.) Removed extra start up items (ViaVoice).
6.) Disconnected all non-Apple USB hub hardware.
6.) Booted from OS X install disk ( in the internal player) and ...
7.) used Disk Utility to check/repair both hard drives.
Here is where the PROBLEMS STARTED.
8.) I intended to boot from the DiskWarrior CD in order to run its tests on both HD’s. The DISK WOULD NOT BOOT. Instead, the screen went gray and I had to eject the disk and use the restart button.
9.) Next I tried to boot from the OS X Install CD as I did before. The screen went gray, a large gray Apple logo appeared followed by a white print on BLACK KERNEL PANIC screen.
10.) Each of the CD’s seems to mount OK and I can access and use the utilities BUT I CANNOT USE THEM AS A START UP DISK ANYMORE. I have tried the “press the C key” method and the Start up Disk control panel designation method without success.
What is the best way to get back the use of the “C” key in order to boot from the CD. And, since I have two drives, could I use one as the assigned start up in system 9.2.2, and used the OS X Install disk to get the OS X onto the other disk.
My efforts to solve this problem have only made matters worse. My new HD won’t mount and can’t be repaired by Tech Tool Pro 2.5. I may have to use the file recovery feature to retrieve what files I can and then re-initialize it. The original HD is also reporting damage but so far it will start up. All the applications are on it, it is the startup disk so I cannot effectively use my tools to work on it.
Please help me to get back to dry land and install OS 10.3.5. Many thanks in advance.

Hello! First, you know now that you should never do multiple upgrades at the same time. That said I'd first look at the most likely which is an error in the hard drives. Often cable select won't work. Make sure the drive jumpered master is on the end of the ribbon away from the motherboard and the one jumpered slave is on the middle connector. New drives are usually jumpered either master or cable select and if you installed it as a slave without proper jumpering then that's the most likely place to start. Post back when you're sure the drives are physically connected properly. Tom

IMac turned off suddenly, won't boot from hard drive/CD drive

Hi guys.
Here is what I have:
27" iMac with:
Core i5 2.7
4GB RAM
Mountain Lion
Win7 on Bootcamp
Lion is installed, but I have the Snow Leopard install disc.
The system had just been recently reformatted so there wasn't really much on the computer itself other than an update to Mountain Lion and a Win7 install via Bootcamp. Other than that, nothing was recentlly installed.
What happenes is I was browsing and all of a sudden it completely shut down. No warning, nothing. Completely shuts down.
Okay.. weird... but when I try to load Mac back up, the Apple logo appears and then after a while of supposedly loading, the screen goes to a plain white screen until I force the computer off. Something similar happens when tryin gto boot into Windows: I get to the "Starting Windows" screen but after that everything goes black and I have to shut down manually.
Great. Now I'll just go into recovery and fix all of this right? Wrong. Can't boot into recovery either. Similar end result: white screen.
Last thing I tried is reinstall OS X Snow Leopard. After loading for about 1-2 minutes, the usual white screen appears after trying to boot from the disc.
I am at a loss. I don't think its the hard drive, because the problem occurs even when trying to boot from the disc. My suspicion is the RAM has gone bad. But, before I go the hardware route, is there any suggestions or recommendations anyone could make first?
In advance, I really appreciate anyone who replies and tries to help.
Thanks.

Xmotox,
I had the EXACT problem today. EXACT. Discs wouldn't boot, I did get the application disc to run the AHT but it said all was fine.
I called my buddy who said something about unplugging for a minute then holding power button while plugging the power supply back in. I thought it would be futile since we already did all the SMC reset procedures to no avail, PRAM reset didn't do anything, etc, etc... But what do you know, up pops the disc utility and my iMac is now restoring from time machine. It's not done yet, so I can't say it worked... BUT it's the farthest we got tonight. Could not get disc utility up via CMD-R or OPTION keys... but powering down, unplugging for a minute or so, then holding power button while plugging the power supply back in did the trick. Hope this helps!

PowerMac G4 (AGP) suddenly won't boot from its internal HDs

Hi, here's a description of a weird and sudden issue on my mac. Hope one of you out there has a cure.
The system: Powermac G4 (AGP) 450MHz, 512MB RAM, upgraded a couple of years ago with an 133 ATA controller card (Acard 6280M). The card controls my two internal HDs of 160GB, which are from two separate brands. Until 1 week ago I regularly booted from one HD with OS10.4.6 (let's call it hd_A), while used the other HD as a data backup space (hd_B).
The problem:
-1 week ago I upgraded hd_A to OS10.4.7 using the incremental package. The system restarted once without problems, but from the second time, all attempts failed. The startup screen showed the flashing question mark: a boot system could not be found.
-I thus booted from the install DVD (10.4) and installed OS10.4.0 into hd_B. The system was then able to boot from hd_B only on the first attempt. From the second, again flashing question mark. Note that on that single successful boot, I verified that hd_A was readable and apparently intact, plus ran DiskUtil which reported no problems on either HDs.
-Running DU from the Install DVD reports no problem on either HDs.
-Running Startup Disk from the Install DVD correctly reports bootable systems 10.4.7 on hd_A and 10.4.0 on hd_B, but attempting a restart from either of them leads to the flashing question mark.
-Resetting PRAM didn't help.
-Holding option during startup brings up the boot volume selection screen with the options of the Tiger install DVD or the 10.4.0 system on hd_B (note that 10.4.7 on hd_A is not shown). Selecting 10.4.0 on hd_B leads, after a delay of a few seconds with a blank screen to a sudden autonomous shutdown of the computer!
Other data:
-The battery reads 3.7V on a voltmeter, so it must be ok.
-Curiously, System Profiler run from the install dvd reports the two internal HDs as 'removable media'. Can's say how it reported them previous to the entire issue.
Thanks, Lo

You can't use the iBook installer on another model Mac. You need a retail version of Panther 10.3 or Tiger 10.4.
If you do a Google search for M9227LL/A (Panther 10.3 retail install CDs) or M9228LL/A (Family Pack), you may find a set. The CDs should be black with a white X.
After you install the base 10.3.x, update to the final Panther version 10.3.9. See Mac OS X 10.3.9 Update (Combo) http://support.apple.com/kb/HT2464
Tiger install DVDs are in short supply. Tiger is no longer available at the Apple Store but may be available for $129 by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753). For other sources, do a Google search for MA453Z/A (10.4.6), MA190Z/A (10.4.3) and M9639Z/A (10.4) . Also look on eBay. Be sure & buy a retail version (black with silver X) and not a model specific version (gray). Expect to pay (possibly a lot) more than the Apple list price of $129.
Also check this web store http://www.lacomputercompany.com/cgi-bin/rpcart/index.cgi?command=dispitem&type= sku&sku=19521
Possible Alternative if you are currently using Panther 10.3 – Do a Google search for Tiger 10.4 Upgrade DVD . It will upgrade your 10.3 to 10.4, but it doesn’t contain the full retail Tiger installer. Should be cheaper than the retail Tiger install DVD.
After you install the base 10.4.x, update to the final Tiger version 10.4.11. Here's the link for the 10.4.11 combo update http://support.apple.com/kb/TA24901?viewlocale=en_US
Look at this link Mac OS X v10.4 Tiger Installing Software Support Page
http://www.apple.com/support/tiger/install/
You can also download the Tiger Installation and Setup Guide
http://manuals.info.apple.com/en/TigerInstall_SetupGuide.pdf
When you upgrade the OS, do it via Archive & Install. See About the Archive and Install feature http://support.apple.com/kb/HT1710
Be sure to select Preserve Users & Settings. Also, repair permissions before and after the install.
 Cheers, Tom
