Please help, mega 180 won't boot, urgent

All all...
I am in deep deep trouble... My mega 180 won't boot, it won't display bios, I tried the reset jumper, unplug the pc, didn't work...
It runs ok with the hi-fi mode. I was using an add on AGP card, but now I unpluged it and trying to use the onboard card. Still nothing is displayed, I want to do a BIOS recovery, but mega 180 doesn't have floppy drive, what can I do? please help.#
Many Thx
Kevin

Was your system working and it stopped ? If so what did you last change ?
Or are you setting it up for the first time and it won't boot ?
What brand of memory and which CPU ?
As Ortrofox says... remove everything you've added. Graphics card, tv tuner, sound card. Then follow the reset to factory defaults in the manual.
Does anything happen at all when you try to boot ? Fan spins ? screen clears ? keyboard lights blink ? beeps ? Is the lan light on in the back ? If you have an optical mouse is the mouse light on ?
Answers to these questions should let us give you some suggestions of other things to try.
Good luck

Meg 180 won't boot from HDD

Repair install of Windows XP appeared to work perfectly, but after install and removal of XP install disk PC wouldn't boot. Noticed initially that IDE drive detect took approxiamtely 90 seconds. Tried a repair of boot sector and MBR, no help. Notice during MBR repair that drive was showing as HDD 2? Attempted boot device order in all possible combintations, (CD, HDD0, HDD1, HDD2, etc,) no help.Moved drive to another computer, boots normally.
Attached HDD to IDE CD-ROM channel in Mega. Drive detect occurrs instantly and computer boots normally. I'd try swapping cables, but that requires more surgery than I feel comfortable with, considering the warranty. Anyone else seen this problem?
Any or all suggestions would be greatly appreciated.

It turns out the Mega 180 primary HDD channel doesn't like Western Digital drives configured with the jumper in the Master position. As Wonkanoby pointed out, the Western Digital drives are defaulted to Master with no jumper. No other controller has appeared to care yet, but obviously the Mega primary channel does. Thanks for all of the tips and especially to Wonkanoby who provided the info that cured the problem. The Mega is up and running now and happily playing DVD's.

Please Help! Macbook won't boot up after attempted Leopard install (Wont bo

Ok so I'll go through EXACTLY what has happened to my laptop in the past day.. please note that the laptop was NEVER moved from the desk while this has all happened. Also a couple other things you should know.. I had Applecare, but 6 months ago when i sent it in to replace the harddrive -- they said they found some water damage, and it would cost $700 to replace... so i just put in the harddrive myself for $50, and it has worked fine since... So I'm pretty sure I can't turn to Applecare anymore...
Alright...
Yesterday
One of my memory sticks went bad on me... (i had 2- 1gig sticks.) I took the bad one out, and the computer seemed to run fine on the single stick of memory.
Last night
I started to install leopard as an update over 10.4, seemed to work fine, though it was slow -- and finally i got to the leopard installation complete thing (please reboot the computer)... so I did...
It starts loading up... shows the mac symbol with the loading circle thing... but wait, Oh ****, i was probally was supposed to take out the cd... So i turn off the macbook by holding down the power button... and I eject the cd, and then try to start it up...
Not loading... ****.
So after some mulling i decide, alright -- i'll reinstall again...
I boot to the cd drive, choose my options, start the install, and go to sleep..
This Morning
I wake up.. the install hasn't moved at all... It's still at the same place where i left it..
****... so again I manually shut it off, and try and restart to boot from the CD again..
NO GO....
If I hold down C to boot from DVD
The computer attempts to read the disk.. CD drive seems to power down.. then try again.. Then it ejects the cd, and goes to the Apple logo with the spinning circle, but never loads. I've tried it with My old 10.4 disk, and the new leopard disk. Same result on both. neither disk seems scratched either.
If I just boot up regular
It goes to the apple logo with spinning circle.
SOOOO...
I tried resetting the PMU, and PRAM
Is it likely that it is my superdrive gone bad, at a horrible time? If so I guess i'll just buy one on eBay and replace it myself. Is there any way to test it?
Could there by another problem wrong with it?
Please help me troubleshoot this! I'd be very appreciative -- I'm a poor college Computer science student that needs his computer to work for his classes.
Thanks All!

Could there by another problem wrong with it?
Yes. You need the two RAM modules, or at the very least the remaining one RAM module must be for sure securely seated. If not securely seated with only one module, the result is as you've seen.
i was probally was supposed to take out the cd...
No, not necessary. After that, the very delayed loading was totally normal, sounds as if you were just impatient.

Oh, and check the AppleCare agreement, as to the best of my recollection, you can should be able to get a refund, pro-rated for time left.
Check how full your hard drive is now. I'm not clear if you've yet erased your HD or how many systems you've installed - if not erased perhaps it's full up.
A PRAM reset should allow you to boot from the install disc, access the Install Discs's System Profiler, and see what things look like. Also, you should be able to boot to the Apple Hardware Test - while you do need a working optical drive to do so, you don't need any hard drive at all, and it doesn't sound like either one has been lost.

Mega 180 won't boot with USB 2.0 device

Well, like a lot of others here I've managed to put the Mega Puzzle 180 together and get it working fairly well. The documentation is dismal and the included "home theater" app is not even half baked yet. The one serious problem I haven't solved yet is that the machine will hang on boot if the USB 2.0 video capture device I bought is inserted. It brings up the green/white AGP 8X screen and just hangs there. It hangs using either the front or rear USB ports, speaking of which it would be nice if they were documented properly as the front being USB 1.1 only.
Has anyone else seen this behavior ?
And if anyone is keeping track, the Toshiba SD-R5112 DVD-R drive works perfectly(as long as your remove the front bezels).
It's an interesting product that looks cool as hell, but doesn't quite work as well as it looks...
CD

Just a thought....
You can disable the Full Screen Logo in bios, and then observe where it's hanging.
On another forum, with completely different hardware/usb devices [DV Encoders] a similar problem was reported. It was found that Norton AV was constantly scanning the USB ports, assuming they were drives. Disabling Auto Protect enabled the boot process, and then were able to configure NAV to remove checking on the suspect ports [drives], and solved the problem.
May not apply in this situation......

Please help: Mega 180 fan speeds

Recently, my default FAN speed when powering up has increased from 2200 RPM to 3000 RPM. I'm using the stock 3.30 BIOS. It stays at this level, which is creating a little more unwanted noise from the case.
Before I swap the fans out for quieter versions, I want to see how normal this is.
Can you post your speeds and BIOS versions?
And if you know a way to slow it down, please let me know too. SpeedFan doesn't recognise the fans, perhaps due to the fact that its support for the LM90 sensor doesn't pick up fan speeds from the Mobo.
Thanks all!
-lajaro

It's not actually the CPU-fan that is causing the most noise. The smaller exhaust-fan is the only one measured by PC Alert (as far as I know, correct me if I'm wrong), and it is quiet enough, even for being a Delta! The problem is the larger (60mm) intake-fan that seems to be running on a constant rpm.
I've tried the Zalman Fan Mate 1 to lower the rpm on the intake. Tuning it down does take away a lot of the noise, but the CPU temperature will increase instead, causing the CPU-fan to spin faster That isn't a big issue however, since it is rather silent...
This weekend I'll be replacing the standard 60mm fan with a Papst. It should be much quieter than the stock fan, but I'll just have to see what happens to the CPU temps. One problem with replacing the fans is the lack of space in the chassis. The original fans are 60x60x15 and 50x50x10, and not much else will fit with the standard HS in place.
One other measure I'll take is to follow johnrr6's advice on maximizing the airflow inside the Mega by removing cable clutter: https://forum-en.msi.com/index.php?threadid=46409&sid=
It seems John's Mega is the quietest thing around, and the coolest running...
Noise just isn't compatible with a Media Center PC, and although an SFF isn't exactly the best chassi for an ultrasilent HTPC, the Mega could do better than this.
Let us know if you try something successful.

Please Help :( iMac 20" refuses to boot up with anymore than 1gb ram?

Please Help iMac 20" refuses to boot up with anymore than 1gb ram? It was fine 4 days ago and had been working with a 1gb stick in one slot and a 2gb stick, which had replaced the orignal 1gb stick that I got it with, in the other and it had shown 3gb of ram and was working just fine with that since November? It went to sleep briefly 4 days ago while I was waiting on a customer and I came back to try to wake it up and it never would forcing me to hard boot it. When I did that it would only go to a black screen with a solid white light on the power indicator. Over and over again and same thing. I read and tried every suggestion I could possibly find in this and a few other mac forums to no avail.
I finally after reading about RAM issues etc. I decided to power off and take out the ram sticks and try them one at a time in each slot. So I took out the 2gb stick and did the SMC reset and it would boot up and work just fine with the 1 gb of ram. So then I went through the same process with the 2gb stick and it would not boot up only go to a black screen with white solid light again (NOT flashing). So then I tried the other original 1gb I had replaced with the 2gb and it worked just find like the other 1gb. So then I tried just 1gb stick in the other ram slot (back facing one) and with just the 1gb strip it booted up and worked fine. Tried it with the other 1gb stick and once again that one too worked just fine. So I determined it wasn't the slot itself I thought? I then tried the 2gb in the back slot and it would not boot only go to the black screen white solid light deal like before. So I thought well ok it's obviously the 2gb ram must have somehow went bad (even though I have only had it since November) and I thought well I will just use the (2) 1gb sticks in each slot and then that will at least give me 2gb because only 1gb really ***** LOL. So I proceeded to go through the same shut down process installed both sticks (I always push them to I feel them click and my fingers have a nice indention on them) reset the SMC and turned the power one and.... It would only go to the black screen with white solid light on power indicator???? I went through the same above process at least 3 times and again today a few times and I can't figure it out and I tried to search and search and I couldn't find anything like what I am experiencing.....What happened? Please help this slow Imac is killing me. It will work with 1gb ram only nothing more? Here are the specifics of my Imac.
It is a 20" Late 2006 Intel Core 2 Duo 2.16 ATI Radeon X1600 256 MB graphics card and Ram with now only 1gb (did have 3gb) and I am running OSX Lion 10.7.5

Please Help in this webcam problem,Its Urgent

Hi,
I have a final yr project by which I can see the picture(whenever I want) of a webcam of a Home PC from my mobile device.
For that I have to write a Java program which will capture the picture from webcam and changed the file format to PNG and then saved it to some directory.Whenever I will run the Java program it will automatically save a picture in the directory and it will do continuously after 5 sec and overwrite the older picture.
Can anyone help me with the code or some sorts of code.
Please help me as it is quite urgent.

Sorry, this forum is for solving specific problems, not for begging for help. If you have a specific problem you need help with, then ask...but I doubt anyone is going to put in the time to help you with a project you havn't put in the time to have specific problems with.

Hello, I want to switch form a individual account to a team/business account? Can you please help me? I need this urgent Thank you!

Please help - Powermac g5 won't fully boot - drive boots in other g5

Here is the deal. My g5 won't boot up now. It starts up gets to the blue screen for about a second and immediately goes to the desktop and beachball spins. The dock loads, but the desktop icons don't and only some of the menu bar does(for instance the clock doesn't show, so there are weird gaps in the menu bar). I've reset the pram,smu,booted in to single user and did fsck. I booted off of the install disc but disk utility says disk is fine though it will not let me verify or repair permissions. When I try to boot into safe mode the fans start screaming, literally almost as loud as a vacuum and it just ends up beachballing on the desktop with no dock or menubar. At work we have the identical model of powermac, so I brought the hard drive in there and it booted just fine. I ran disk utility and repaird the permissions. Took the drive back home and still won't boot. So I reinstalled the os (archive and install) but still won't boot.
One thing to note, I updated the firmware on my superdrive with newer pioneer drivers the day before this started happening. Could that be the problem? Any help would be greatly appreciated, I hope my computer is not bricked here.

anyone think it could be the logic board (crazy fans) or maybe the processors even? Sorry to bump this up but I am desperate to get this working again.

Pwrmac dual 1.25 FW800 Won't Boot, URGENT PLZ HELP

Hi
After playing with the ribbon cables, trying to plug and unplug a HD near the superdrives, in order to format it with disk utility, it didn't work so i gave up and went out.
When I came back the computer won't boot.
Power light comes on for a second, but goes off, no chimes, no boot.
I tried resetting that motherboard button, but it did nothing...( i forgot that that button is called I used to do it on my g3.)
ANY IDEAS?
thanks

HI-
ANY IDEAS?
Did you unplug whatever it was that you plugged in?
In the process, did you disturb any other cables/connections?
Double check all cables, especially the motherboard cable, and the power button board ribbon.
If that doesn't help, unplug the machine, remove the PRAM battery, wait 15-30 minutes, install the battery, plug in the machine, and try again.
I tried resetting that motherboard button, but it did nothing...( i forgot that that button is called I used to do it on my g3.)
That would be the PMU, or CUDA button.

Please help me... Its urgent

There was a recent posting which suggested two things
to say if you want to be ignored are put "please help
me" or "urgent" in you subject. You put both. :)
It is likely that you program is throwing an
exception as an error, but you are ignoring all
errors so you have know way of knowing what the
problem is.
Try printing out your exceptions, they may tell you
what the error is e.g.
e.printStackTrace();Hi
I am getting the following exception :

HELP! Comp Won't Boot!

HI. I have a computer that i just finished putting together a couple oif days ago and for some strange reason it wont boot. The D Bracket shows led 1,2, and 4 red, while 3 is green. This is "Initializing Keyboard Controller." I have tried removing the battery and setting the jumper to clear to clear CMOS but still it won't boot. My screen dosen't come on and the only thing that really happens is the fans spin. I haven't reset any settings on my Mobo. I have my Win XP disk in the CD drive because I don't have an OS installed yet but it won't start. Can anyone Help Me PLEASE!!!

First of all - have you tried another keyboard ( ordinarie ps/2 ).
Other things that could give strange problems;
- check for if Motherboard shorten / chassi contact ( check standoff´s between the MB and chassi - correct mounting and right number at the right place )
- reseat your cpu
- reseat memory ( other memory ) and test other slots

OMG PLEASE HELP ME! WON'T START UP AND SCREEN LOOKS FUNNY O.O

Okies, my sister was on my macbook pro all night, and i just finished updating some program (the mac version of winzip?) and the comp froze and had little rectangles all over it, like tiny TVs with bad reception on it O.o
So i hold down the Power button to reset it, then turn it on, the little rectangles are there when the grey screen with the apple on it, then it goes to a blue screen and stops
I can't do anything! I even have my install disk in it cos i thought i might need to restart it that way and now it won't come out T_T
Please help! I don't know what ive done, i've only had it...less than a week!

Couple of things I'd do here:
1. Restart your computer.
2. While the computer restarts, press the trackpad button and hold it down through the boot process. During the normal bootup process, this should tell the computer to eject the CD.
After that, follow these steps:
1. Turn off your computer again.
2. Unplug all cables including the power cable
3. Take out the laptop's battery.
4. Press the power button and hold it down for 5 seconds.
5. Put back in the battery.
6. Plug in the power cord
7. Press the power button to start the computer
8. As soon as you here the "bong" noise (the startup noise) press and hold down the following keys: Command Option P R (that's four keys all together including the letters P and R)
9. In a few seconds, the computer will go "bong" again (i.e., present the startup sound). Once that happens, let go of the keys and let the computer finish booting.
Did this work to solve your screen problems?

Help! Powerbook won't boot..

Hello Mac Users;
I'm looking for some help! I was just sitting here at my desk playing a game on my pc, when I look over at my powerbook, an update has come up. Itunes and Mac OSX update. I reach over to do the update, type in my password, close Itunes, update goes through the process. Finishes the update, and then says I need to restart. I restart the Powerbook, and says something about entourage fails, and the ball just continues to turn for about 15-20min. I panic, press and hold the power button to turn it off. I restart the Powerbook, and hear the ding like it is going to start up, but the display is blank, upon further investigation, I can see the apple in the back ground and the gear turning. The backlight isn't coming on, and the fans will turn on when I power it off, and power it on.. I think I have reset the pvram or whatever, by taking battery out, and holding down powerbutton for 5 secs, I power it back up and still doing the same thing. What happened, and is there anyway for me to get this fixed? I do have apple care, but last time they had to replace the logic board it took 2 weeks. I would try to put in the tiger cd, except I watch the movie Blow this afternoon on it, and it is still in there. I tried to eject the dvd and it won't do anything.
Please help me. What can I do?
Cliffs;
1. update
2. won't boot
3. lcd backlight not on;
4. can see apple and gear
5. tried pvram reset
6. dvd in drive
7. Help?
17" Powerbook G4 1.67ghz

Hello Brandy,
If you cant see the screen at all, or if its very dark...like theres no backlight, i would suggest this to remove the disc.
immediatley after boot chime, press and hold the mouse button on the trackpad. this will automatically eject the disc in the drive, and make life easier for you.
also, try(seperately to removing the disc), after you hear the boot chime, press and hold apple-option-P-R, all together, untill you hear a second and 3rd boot chime then let them go. this may help revive your screen. otherwise, take it on in to the apple service provider. hopefully its something simple, but you never can tell.
let me know how u went

Help! Imac won't boot anymore.

Hello. I am in DESPERATE need of your help. I have mac os x leopard and yesterday i update it, but the power went out in the middle of the update. now when i start it it just shows the apple icon and the small rotating wheel.
When i boot up in the Verbose mode, it just goes "Server: mdsync launch failed: (ipc/send) invalid destination port" and then 3 or saved crashreports with the loginwindow and a bunch of nubrs.
Its stuck in this loop and it just goes on and on.
I tried booting up with the cd it came with, but no help, disk utility AND fsck said its ok, in safe mode it dose not want to boot, it just stays in that grey apple rotating wheel screen.
I tried instaling it again, but with the UPGRADE feature, because i have lots of data on the machintosh HD main drive in some folders, and not in a user folder or such, so i can't use the archive and install, because i will lose all data.
Please help!
Thank you,
Sebastian

You can use Archive & Install. This moves the System folder to a new folder called Previous Systems and installs a new one. Other folders that exist on the drive won't be affected. Nothing is deleted in an A&I, only moved.
As a matter of tidiness, it isn't a good idea to have folders sitting loose in the root of the drive. You are much better off having them in a User folder; either your own or the Shared one.
I recommend an Archive & Install, as you have undoubtedly corrupted your OS when the power went out. You may have to reinstall some apps, but your Mac will boot.

Please help, mega 180 won't boot, urgent
