BSOD: 0x7F on XP

Posted on


The machine in question is a Dell PP22L laptop. After logging on, the system will act normally, but slowly, for about 5 minutes before going to a BSOD with the following details: (shown by using BlueScreenView)



The only way to know for sure is to get a kernel dump and use WinDbg.exe to get the stack trace and find out what kernel mode code was involved in the crash. Most likely it is a driver.

To properly diagnose this error you need to configure your machine to create a proper Kernel Memory Dump (not a mini dump) and make sure your page file is large enough to hold it (physical ram + 1mb).

Once you have a proper dump, you can use the downloadable Debugging Tools for Windows to install WinDbg (pronounced wind-bag by the cool people). Debugging kernel dumps is not for the faint hearted. Here is a guide to get you started.



One of the many processes or threads
crucial to system operation has
unexpectedly exited or been
terminated. As a result, the system
can no longer function. Specific
causes are many, and often best
resolved by a careful history of the
problem and the circumstances of the
error message. One user, who
experienced this on return from
Standby mode on Win XP SP2, found the
cause was that Windows was installed
on a slave drive; compare KB

If this doesn’t help, please supply additional information:

  • Are there any error messages in the Error Log?
  • Have you added/replaced any hardware just before this started?
  • Have you installed any software or drivers just before this started?
  • You might run Memtest86+ to check the computer memory

I have had 2 pc’s go through my shop in the last 2 weeks with the same bsod. One had a faulty hp printer driver causing the issue, a quick removal and re-installation of the software and driver resolved it. The other had some minor partition problems that were resolved by running a 5 stage check disk, the guide is for vista but the steps are the same in xp anyway.

Past that some further internet research had another 2 computers, one fixed his issue by replacing the bios battery (unfortunately not easy on a laptop). The other resolved the problem by running memtest86+ and discovering a faulty memory module.

Please run some tests and tell us if you find anything.

Good Luck!
