New machine won't boot

I've had this new machine up for about a week and a half, and all of a sudden it started hanging (freezing) on me tonight. Other than the drivers, utilities, etc. that came w/ the various hardware, I haven't installed much software: Office 2007, Firefox, AIM, and one game (TimeShift). Everything was working great until tonight. Except I had noticed that when I left the machine for a while and it went to sleep, when I tried to wake it up by moving the mouse, the screen would come up w/ my background and nothing else. I would have to reboot to get it going again. Tonight it all escalated. It first hung when I was using Firefox. Next time it was after I saw a brief message about an 'access error' on the raid mirror. I then went into the nVidia Control panel, and it froze again. No response from the keyboard or mouse at all. Sometimes, the mouse pointer would disappear completely, and w/ still no response from the keyboard I'd have to reboot. The last time windows was up, I tried to see if the game would start - it froze again. After I pressed the reset button that time, it has not booted again.
I'm using the software raid (Raid 1 mirror), and it says the mirror is "healthy". I can get into the Raid Setup and everything looks fine. But when I get past the post, right when you're supposed to see the Windows moving bar, I hear a faint 'click', and then nothing - black screen. I can also get to the BIOS just fine, and nothing appears to have changed. It's possible that one of the hard drives is bad, but after all the trouble I had trying to get Raid to work on this board (cold boot issue, etc.), I also think that the board may be suspect. I guess I will try disconnecting one of the drives, and see if it will boot off of one or the other. But I would sure appreciate any other suggestions too!
TIA

Well, I found I can boot off of the first drive (slot Sata 1), but not the second (slot Sata 2). So I guess it might be the hard drive which is having a problem. The odd thing is, that when both drives are plugged in, it won't boot. If I disconnect the second one it will boot. I thought that was the purpose of mirroring - if one drive went bad, it would boot off of the good one, and then you replace the bad one and rebuild your mirror. Perhaps that means there something wrong w/ the nVidia raid?? I've never used raid before on a machine, so I don't have any experience with this sort of thing. Any suggestions would be greatly appreciated!
No, the mirroring means you have a safe copy of your data, you will still need 2 disks........

Machine won't boot

XP Pro
AMD 64 3000+
MSI K8T NEO MB
I was installing some windows updates and another piece of software at the same time. The other software finished first, so I clicked ok - and it auto-rebooted my machine (gdammit I hate that). Now my machine won't boot at all. Black screen with no data being sent to it, no error messages, codes, beeps ... NOTHING. All the fans are on, the CD light blinks a few times, hard disk seems to spin, but NOTHING AT ALL happens.
What can I do to fix it if I can't get to *ANY* bootable device?
I noticed the cd light blink, so I put the XP install disk in, but that did nothing. At one point after a cold boot, the floppy turned so I popped in a boot disk ... crunch, beep, repeat. That was no help either.
Someone said I should reset the bios/cmos via the jumper on the mobo. Someone else suggested I disconnec the PS for a minute, reconnect and try again.
Ideas? Please help me.
Thanks.

...that is good advice...I would add that you unplug (either at the wall or at the back of the power supply) the PSU when you clear the CMOS...clearing the CMOS is a vital troubleshooting procedure...
...what was the other software?..just curious...

Help - My machine won't boot and I cannot get into the BIOS - 990FXA-GD65

I have been trying to install an AHCI driver for use by WinXP, so far with no success (see this link: https://forum-en.msi.com/index.php?topic=161637.0 )
However, following my last unsuccessful attempt, I had to take a break from running any more attempts and switched off the machine for several days.
I have come back to it tonight and I find that the machine won't boot at all and that pressing DEL or F11 after starting won't take me to the BIOS or the boot menu. The display shows nothing, other than 'No HDMI signal'
Are there any tests I can do to establish what might be wrong?
pbb

Thankfully the machine has come back.
I tried a couple of cmos/battery clears, with no success.
Then I took out one stick of memory, cleared the cmos and it all worked on rebooting!
I put back the memory slug, cleared cmos again and it continues to work!!
What a relief - thanks xmad.

New X2270 won't boot OpenSolaris 2009-06 from internal disk

Is anyone having any problems with recent X2270 servers? I took delivery of two of these last week. They are without the ILOM card because Sun are having quality issues with them - a firmware bug I believe. They are fun to install as my only eyes is via a serial port that seems to have some kind of bios video text to serial ascii emulation which has quite a delay on it.
Basically after installing Solaris it won't boot from the internal disk. So far I've tried net installs of SXCE b105 and also the latest OpenSolaris 2009-06 and in both cases the install completes correctly without any errors (that I've detected) but after rebooting they fail to load the kernel. Here is what's left on my serial console:
Press F2 to run Setup (CTRL+E on Remote Keyboard)
Press F12 if you want to boot from the network (CTRL+N on Remote Keyboard)At this point the hard drive activity light flashes twice and then the machine appears frozen. The Solaris banner is never shown. I've left it like this for hours just be sure.
I've chosen ZFS for the whole disk in both instances. I wonder if this has something to do with it.
Presumably OpenSolaris has the drivers for the disk interface cards otherwise it wouldn't have been able to install onto the disks.
Any advice greatly appreciated.
Kind Regards
Jesse

New HD won't boot internally; fine externally

I'm trying to swap out the hard drive on my wife's late-2008 Macbook with a new Western Digital hard drive (regular style, not a solid-state drive). Cloning the drive with Carbon Copy Cloner seems to have worked fine (including the hidden Recovery partition) as it can be booted from in an external USB case on startup. The problem starts when I switched out the old drive and placed the WD inside. All of a sudden the Macbook won't boot up and I get the flashing folder icon instead. Switching the drives back and everything's fine; I can again boot up from either drive by holding the option key on startup.
I've read that some older Macbook Pros have an issue with SATA II data transfer rates and need to be slowed down from 3.0 Gbps to SATA speeds of 1.5. Unfortunately, it according to WD's site you can't do that with WD's 2.5" drives, only their 3.5"s. I've tried it anyways with a jumper and it doesn't seem to work for me.
I've also read elsewhere that there is a limit to the size of the drive that can be placed in: 500 GB. The drive I bought is 750 GB, so if this is true, that could be what the problem is. However, I can't find any mention of this supposed limitation anywhere on Apple's site. Does anyone have a reputable source for if this is true for this model of Macbook?
Late 2008 13 inch Aluminum MacBook running Lion
Western Digital Scorpio Blue (WD7500BPVT) 750GB SATA 5400 RPM 8MB Cache 2.5" Laptop Hard Disk (OEM)

Hi Dave, I am having the same issues with a WD Blue. Thanks for your suggestions, but doesn't work for me.
When the WD is in the MBP (15" 2010 Unibody), and I boot from an external HD, firstly the MPD says it can't recognise the WD and offers me the choice to Initialise, ignore or eject. I select initialise and disk utility reports that there is only a FAT partition of 58.2 GB on the WD. Err?
When I put the original HD (an ST950032 500GB) back in the MBP and boot off it, all is fine. I then put the WD in an external exclosure, and the MBP sees it fine and Disk Utility correctly reports a MacOS Journalled GUID partition of 465.8GB.
All the data is there (from doing an earlier clone). I just can't boot off it - weird.
Surely there is a fix for this? Have tried all the SMC / PRAM reset stuff.
The box even says that the WD Blue is 'Suitable for all operating systems (except XP) out of the box". How can you be sure that a drive you but will work in a MBP before you spend your money?

New Mobo won't boot

Can someone help me out? I just built a new machine with KT4 Ultra mainboard, Athlon 2200+ XP CPU, and Kingston DDRAM 512M/333 PC-2700 memory. I have Win2000 installed on the HDD already, and I am trying to get it to start up. Power on: All fans and drives pwr up and ethernet card lights come on. Monitor stays in black screen, memory does not count up, keyboard does not test or respond, no way to shut down but hold power button for 8 seconds. After several attempts, I took out the new 512M Kingston memory and installed APACER 256M PC133. System started normally and booted through windows security screen. Windows began finding and installing drivers for the new mainboard, and needed restart. I let the machine restart, and now had the same problem again. It comes to black screen and I can't even get to the bios setup screen. I don't have any more memory to try this again, but I put the 256 stick back in my old machine and it works fine. I have built lots of machines, and never had this problem before. What's up?

I would start your system with default BIOS settings or play with chipset features in your BIOS.
Also, eliminate all expansion cards except video card.
Leave all fan connectors alone for now, except the CPU fan connector of course. For testing purposes you need the simplest possible configuration. You can add other components one by one only if you have steady system.
Hope this helps,
Take care.
Thanks for your response. I haven't been able to get the bios screen to display, so I can't do anything with it. I have not used any of the fan connectors except the cpu fan (of course) and I haven't tried to start the board without a HDD yet. I will do so tonight when I get back to it. I also have a spare video card that I will try, but so far, all of my parts work fine (including the memory) in my Shuttle AK31 mainboard.
Do you have any advice for me when I have to pull my CPU fan and processor off this board? I don't want to take any chances that I might damage it when I attempt to clean off the thermal tape and put more on. Do I even have to replace it?

How to open CD drawer when machine won't boot?

I am having the Firmware default catch error and need to boot from CD, but I cannot get the CD drawer open!
Eject button on keyboard is inop since system won't boot.
Inserting paper clip in hole under CD drawer does nothing.
Help!

If the Mac were normally left unplugged from power, and hence draining the PRAM battery, it could certainly be bad by now. But any Mac that's been on for a year or so isn't likely to be unplugged much! My 700 MHz eMac is still on the original battery (and plugged at all times into an APC BackUPS). Still, the battery could be physically bad. If you have a voltmeter handy, you can check if it's within say 0.1v of the nominal 3.6v while under load (still in the battery holder). You can find the replacement 3.6v lithium 1/2 AA battery online (e.g., cyberguys.com) for around US$11 after shipping/handling (in-stock at Radio Shack, the same battery is currently going for $20 before tax).
If there are indications that the eMac is running hot (like the monitor colors going funny), check the air intakes on the bottom of the front of the eMac and make sure they're clear of papers, cat hairs, and the like. If the rear vents look dusty, you can either disassemble the rear cover to wipe the vents and fan blades clear, or just use the quick solution of using canned air to blast the rear vents at about a 135 degree angle pointed away from the eMac, with the eMc on so that there's airflow pressure out of the chassis (to prevent dust from being blown back into the eMac's circuitry).

Changed access permissions now machine won't boot. Utilising deep breathing techniques until help appears.

Maybe a brain snap but I changed the access permissions on the hardrive to everyone-no access, what do I need to do. After 20 minutes of beachballing I pmowered down, and now it won't boot up, gets stuck on the apple boot up screen. There also exists in permissions another access setting admin-readwrite. Would appreciate some heads up on what I can do (trying not to panic).

New Air won't boot after failed Migration

New MacBook Air arrived this afternoon.
First thing I did was run Software Update to apply the lates OS patches.
Second thing I did was run Migration Assistant to transfer data from a Time Machine backup on an external USB disk. The old computer was small. Backup is only about 25GB. It is from a MacBook running Snow Leopard.
After about half an hour of running, Migration Assistant reached the "less than a minute remaining" stage and hung there for more than an hour. Finally I quit it. My computer then became unresponsive. I had to hold down the power key and restart.
Computer won't restart. Bong is heard, Apple appears, spinner appears, no progress after that. Unplugged the external disk, rebooted, same thing.
I rebooted to the recovery partition and ran Disk Utility, did the integrity check and the permission repair on the main volume, no improvement.
Finally I gave up and started the Reinstall Lion option. I'd read about this, figured it was something I might need someday, never imagined I'd be running it within hours of getting the computer. Display says I have 5 hours and 45 minutes to wait.
What went wrong here? What should I do when it is done reinstalling? I'd like to have my old stuff back, but I don't want to kill my computer again.

For what it's worth, booting stops at the "Waiting for DSMOS" step.

Brand new iMac won't boot :-(

Hi All,
I just got a brand new iMac. I did a clean install of Leopard, imported a couple of CDs into iTunes, and then thought I'd give Bootcamp a go.
I created the disk and the machine duly rebooted into Windows setup. As the installer couldn't see the Bootcamp partition (I was using XP without SP2). I told the installer to quit and reboot.
Now all I get is a hanging white screen when I power up my iMac. If i hold down the Alt key I get a mouse pointer which locks up after a couple of seconds and that's it.
I've tried:
- Holding down alt on bootup - this brings up a pointer which locks after about 2 seconds
- Holding down alt+C - with Leopard in the drive - nothing happens
- Zapping the PVRAM - AltCMD+PR" - this had no effect
- Resetting the SMU - hold down power whilst plugging in - now all the fans are running at maximum speed
- An open firmware update as per this post:

Is the machine completely toast?

The same thing happened to me this last week. After talking to Apple on the phone for hours they decided that it was dead and declared it doa (even though it was working for a few hours before boot camp). I am getting my new one this week. I can promise you that boot camp will not be put used on this one.

Has Mavericks gone all maverick on my 2010, 27" iMac? Long story, short: Replaced 'bad' HD with identical model (1TB), reloaded apps, + got external 2TB HD. Fan was running high, now machine won't boot in ANY mode.

I have a mid-2010 iMac (27") 2.66 GHz Core i5 (750) with 4GB RAM that I bought second-hand almost three years ago. It worked perfectly...until I 'upgraded' to Mavericks last Fall, & all my trouble began. At first, certain apps started getting kinda wobbly, especially Chrome which was really unstable. Eventually one day on boot-up I got the gray screen/apple logo/spinning wheel/loading bar--and then it would shut down. I got apple care on the phone and we went through a laundry list of various tests and start-up attempts. We reset PRAM, got me into safe mode and eventually hit a point where we were going to have to wipe the HD and start fresh--except I didn't have a back-up (shame on me!). He told me 1) the error code that came up after running disk utitility (?) indicated no problem with HD and that it was software related; and, 2) to take it into Genius Bar, have them backup data and then I could call him back and we'd do the deed and then reinstall with backed-up files. Tried but Geniuses said, "We don't do that" and told my hubby how to. We bought the equipment and prepared to back-up using my son's MacBook Pro. No glory. Nada.
After much back-and-forth with 'geniuses' and guy on phone, we took it to MicroCenter. Their diagnostics said HD is shot--get new one. After pricing everything out we went with iFixit's instructions, and I ordered the identical (I thought) HD for Mac online from manufacturer. We installed it, but had wee problem with LCD temp sensor and so fan ran like crazy. I also bought a 2TB external back-up and did routine back-ups, so I should be good there. I am aware of that third rail on the HD's with sensor but thought I could circumvent that and 'knew' it was really the LCD sensor that was the problem. I was traveling for months all winter/spring so didn't have time to devote to a pesky fan noise. HOWEVER, with increased use being home for several weeks, suddenly we are back to square one it seems. One day the machine shut down and has not rebooted since--about three weeks ago now. Haven't called apple care but tried to reset PRAM and tried to restart using thumb drive where I thought I had saved a copy of Mavericks--didn't work so don't know for sure if it's on there. I opened machine back up and saw that LCD sensor wire was not connected and falling apart. I ordered a new wire which installed tonight with no apparent problems, crossed my fingers and...NADA. Same-o, same-o: gray screen, apple, spinning wheel, loading bar...then it shuts down and goes to black. I have tried to restart with all kinds of codes: reset PRAM, safe mode, hold down option key, hold down Command+R...again, nothing. I even replaced the keyboard batteries. As the progress bar fills up near the end, I hear a little click and whirr, fan running softly, but then it just shuts down. I should mention that the PRAM reset did actually start out like it was working--it shut down/restarted but then the daggone apple/gray scree/spinning wheel/progress bar would kick in again...and then shut down 5-10 minutes later. Any ideas, folks? Please help?

Your internal hard drive is not good.
Your Time Machine drive with your backups on it, if these backups were created using OS X Mavericks version of Time Machine, these will not be accessible by early OS X versions of Time Machine.
Plus, Time Machine stores data and nothing of the OS X system.
Plus, you want to save/retrieve your data that is still on your iMac's internal drive.
So, we can try to get your iMac back to running OS X 10.9 Mavericks.
The most easiest and direct way to do this is to just purchase another external 2 TB hard drive (preferably a fast FireWire 800 external hard drive)
You can use your OS X Snow Leopard install DVD to format this new hard drive as an OS X Extended Format with GUID partition scheme.
Create two partitions on the new external drive one that is big enough for OS X and all applications (say 500 Gbs) and the remaining partition for storage so you can manually copy all your important data ( and maybe your Applications folder, too) from your Mac's internal drive (if it is accessible) to the large partition on this new drive.
Once the drive is formatted using the Disk Utility app that is on your OS X Snow Leopard DVD disc, you can then proceed to install OS X Snow Leopard to this new external drive and now giving you a bootable hard drive that will have a fairly fast, working OS X version your iMac can boot to, now.
Once OS X 10.6 Snow Leopard is install to this new external hard drive, you need to boot to this to get up and running.
Use OS X Software Update feature to get you back to OS X 10.6.8 Snow Leopard so you can regain use of The Mac App Store.
You have two options, now.
You still need to attempt to manually copy over all your important data and applications over to the large storage partition you created on this new external drive.
Once you have done this, you need to search for, purchase, download and install a data cloning app, like CarbonCopyCloner or SuperDuper to be able to clone your new hard drive's system back to your iMac's internal drive once you have resolved/replaced you iMac's Internal hard drive, again, if it is damaged.
If you still want to be able to access your Time Machine Backup drive, you can go ahead and try to re-download OS X 10.9 Mavericks ( you may need to use a Combo Update version from the Mac App Store, now as Mavericks is up to 10.9.5, now. You will upgrade install Mavericks over your new OS X Snow Leopard partition on the new external hard drive.
If, successful, you should be able to access your Time Machine backup at this point.
You will be running your iMac from this external drive until the internal drive is repaired/replaced.
The other idea is if you do not care about your Time Machine backups on the other drive, you can foresake the data on this drive and keep this new external drive , and your iMac, running OS X 10.6.8 Snow Leopard and forget about upgrading to Mavericks, at all, since you had so many issues with it.

NF750-G55 New Build Won't Boot to DVD

I'm doing a rebuild of a system in which the old motherboard failed. This is only the second time I have done a build, so forgive any apparent ignorance. The following describes the system: Motherboard: MSI NF750-G55, CPU: AMD Athlon II X3 450, PSU: Hiper Type R MkII 880W, Case: Antec Three Hundred, Memory: Rendition by Crucial 1 X 4GB, Hard Drive: Seagate 400 GB, DVD: Samsung 22X SpeedPlus. Only the case, PSU and DVD come from the first build I did 18 months ago and were fine until the old MOBO failed.
The problem I'm encountering with the new MSI NF750-G55 is booting to the DVD so I can load Windows Vista onto the hard drive. The POST gives me a Bad CHKSUM error and directs me to bios setup. In setup, the Boot Sequence shows my DVD and hard drives as disabled and won't let me enable either.
I've uninstalled everything, cleared the CMOS and reinstalled everything five times. Nevertheless I am still getting the same error message and can't enable either my DVD drive or hard drive. Therefore, I'm unable to successfully boot up and load windows onto the new hard drive.
I'm out of ideas and ready to return the MOBO to Newegg for another, but I would rather fix the problem. Does anyone have any ideas as to what I can try next before I ask for an RMA?
Thanks in advance for any help you can provide this newbie.

Quote from: Pixy on 16-April-11, 04:24:53
I've tried loading defaults (both optimized and fail-safe) in bios setup as well as by using F2 in the chksum error screen. All result in a screen that looks like this:
The text that is obscured in the upper part of the screen reads:
BTX loader 1.0 BTX version is 1.01
Console: internal video/keyboard
Bios drive C: is disk 0
Bios 636kB/2030208kB available memory
Once in that screen, the only way out is to unplug the PSU and reset the CMOS.
As I said before, I'm stymied and have no idea what to try next.

do not do this, just hit reset button then press F11 during BIOS post screen and boot from your optical drive.

Re: KT6V New system won't boot.

Similar problem here...
I got new (bought in one week) KT6V, installed Sempron 2500+ and 256MB DDR400 but I never boot it successfully.
No video signal seen in monitor, monitor led always stays orange. I removed all PCI card and also unconnect HDD and CDROM powers to test, but it is same...
I donot know what the problem is, and donot know what I can do next
Because of the no screen, I donot enter BIOS, I checked many times my video card...It's tested on another machine, no problem with that...
Waiting your comments urgently...
Thanks...

Your Mobo isn't the same of first post, so it's possible you could get wrong or less advises than you could get with a new post. Also, it seems that you named it wrong: Shouldn't it KT4AV ? Your'e using 2 Difs. memory. Better take the 128 out at least during troubleshoot. 300W P.S. may be too poor, that's why you have beeing asked to tell it's specs.

New MacBook won't boot from external disk

I have a new MacBook that I am trying to boot from an external disk that had the system from my first gen MacBook Pro. When I restart holding the Option key, and select my external disk, the system restarts again and won't let me boot from that disk. Is there something different with the OS (10.5.6) that is installed on a newer MacBook that won't allow it to boot from the same OS from an older MacBook Pro?
Thanks

golferx,
Will any other Intel Mac boot from the drive? If not, it's possibly because the drive uses an Apple Partition Map (bootable for PowerPC Macs) instead of a GUID Partition Table (bootable for Intel Macs).
To check: open to Disk Utility, select the hard drive on the left, select the Partition tab and look at the text at the bottom right corner of the window under Partition Map Scheme. If it says anything other than GUID Partition Table, you will need to erase and repartition it as such before it will be bootable.
Just a thought. Hope this helps. Good luck!

I can boot an prev gen MacBook and also my iMac (current gen). I took it to the Genius Bar and he could not get it to boot a new MacBook either and didn't have a solution.

Migration Assistant crashed new iMac, won't boot

I bought a new i3 iMac and skipped the migration assistant initially. Things were going fantastic, I imported and built a new iTunes library, iPhoto library etc.
It is running 10.6.6.
Then last night I decided to use Migration Assistant to move things from old Intel MacBook (running 10.5.8). As the migration was going to be something like 20-30 GiG's, I unchecked everything except Applications, and a few select folders from each user account (Documents, Desktop, Pictures, Movies). Since one account had the same name as the account on my new iMac, I asked Migration Assistant to rename the old account. I then went to sleep.
When I woke up, iMac screen was black and would not wake up from sleep. Old MacBook tells me that the connection was dropped.
I had to depress power button to force shutoff. Upon restart, at the apple boot logo, all I get is a message saying the computer has to be restarted, which appears in multiple languages. There seems to be nothing I can do to get it to boot.
Help?

Hi, and welcome to the forums.
That's likely a complication. You'll now have an extra user account with that stuff in it, and the account(s) you transfer won't have permission to it.
I had to depress power button to force shutoff. Upon restart, at the apple boot logo, all I get is a message saying the computer has to be restarted, which appears in multiple languages. There seems to be nothing I can do to get it to boot.
That's a *kernel panic.*
They are usually caused by hardware problems, but can be software.
Try running this: [Apple Hardware Test: iMac (Mid 2007) and later models|http://support.apple.com/kb/HT1883]. Run the Extended tests.
and the (free) Rember, a heavy-duty memory tester, from: http://www.kelleycomputing.net/
If that doesn't help, start with this Apple article: [If “You need to restart your computer” appears|http://docs.info.apple.com/article.html?path=Mac/10.6/en/8965.html].
Once you get it started, check the transferred user accounts; most likely, the transfer was incomplete, and you'll have to delete the partial accounts and run the Migration again.
If your Apps were only partially transferred, just select them again -- Migration Assistant will just skip any that already exist on the new Mac. The only problem you might have is if it was in the middle of transferring an app when it failed; in that case you may have a partial copy of the app.
