Need help: Bad_pool_call blue screen just before startup

by Landsburger / March 29, 2008 7:05 AM PDT

Hi all,

I could really use some help. I'm just about finished with a huge project, but I now can't start up my computer. What's happening:

Windows XP, sp2

On startup, it get's all the way to the where it says "window's is starting up" (when it's about to give you the options to select a profile), and I get the blue screen of death. Part of the info:


Stop 0x000000C2 (0x00000043, NOTE:the following nummber is always different: 0xDC2B000, 0x00000000, 0x00000000)

I've tried to boot in safe mode(s), but it still crashes at the same spot. Any ideas? I'm really in bad shape.

Thanks for the time. I appreciate it.

Take care,

Bad driver?
by MarkFlax Forum moderator / March 29, 2008 7:25 AM PDT

From this site; it looks like a bad driver is responsible. At that site click the C2 link in the right hand column. Check the XP links for Microsoft Knowledge Based articles.

No details of your computer but did you make any hardware changes recently, or upgrade any drivers?

If you can get into Safe Mode you may be able to disable the driver in Device Manager or see if it is a graphics driver changing the screen resolution to the lowest possible allows you to reboot into normal mode and retrieve your work.

Safe mode guidance here;

Thanks for the info.

I did install a few new programs (MP3 converter and CD cover designer) but I'm fairly certain I've rebooted since then (although not positive).

The problem now is that I can't even get in using safe mode. What are my other options?

If you cannot get into Safe Mode

In reply to: can't get in

then it is not looking promising.

I missed where you said in your first post that you had already tried Safe Mode, sorry. Does that mean you cannot even get to the Safe Mode list of options? Or can you get there but when you choose the first option then loading fails?

If you can see the list of options, have you tried "Last known good configuration"?

If that fails then your options are limited. You could try a Repair Installation of Windows, or I believe others here would suggest to remove the hard disk, and install it as a slave in another computer. That way you could possibly extract your documents and files. You may have to "Take Ownership" if you do that;;en-us;308421

How to perform a repair install

Searching google for bad_pool_call doesn't look promising. It could be a hardware issue or a corrupted registry, for example.
A repair install won't help in either case. A clean install surely helps against a corrupted registry (because it makes a totally new one), but hardware issues could still cause it to fail.

Things to try: about recovering from a corrupted registry

Hope this helps.

Thanks for the info and the links.

I did try last known configuration", and most if not all the other safe mode options. Is there anything I can "turn off" in the setup that might be causing the hardware problem?

Does how far I can get into the boot-up give a clue to what could be the problem (it's right before it shows you your profiles and it's saying "Windows is starting up...")

It looks like, if I can somehow find my XP disk, I can maybe replace the registry.

Is getting the info off my 2 discs in that computer as simple as pulling them out and placing them in a working computer? If the drive was previously a C/bootable drive, do I need to do anything special?

If it is a hardware problem, how in the heck do I diagnose what it is?

Thanks again to all for the time.

In reply to: update

Getting things of the hard disks is as easy as mounting them as slave in another PC or putting them as external disk in an USB enclosure. Those are $20 a piece or so.

If with a new hard disk it boots from the Windows CD, makes and formats a partition, installes Windows XP and runs it without problems, it most likely isn't a hardware issue, or an issue with one of your current hard disks. If that clean install scenario fails, it's a hardware issue. Then remove hardware until the bare minimum (motherboard, hard disk, CD-drive, keyboard, mouse, video) and try again.

"Is getting the info off my 2 discs in that computer as simple as pulling them out and placing them in a working computer? If the drive was previously a C/bootable drive, do I need to do anything special?"

Some will put in a new hard disk, reinstall the OS then add a drive to get their files out. That's the usual and CHEEP compared to repair counters.

Repair of this OS is not always possible or rather the extreme methods I use are not easy enough for me to share here. They involve Linux boot cds and more.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
