Old IBM laptop running XP Professional, version 2002, sp2, went into Blue Screen death during a reboot attempt in order to run a boot time scan by Avast AV (full purchased copy) that was updated just before rebooting. That same morning MS did an auto update and successfully rebooted. Thought there might be some sort of conflict between updated versions of MS and Avast, but have not yet tried to remove current version of Avast to test that assumption, hoping to get some input here as to what else the problem might be.
Blue Screen displays:
Stop 0x000000D1 (0x0..5c, 0x0..02, 0x0..00, 0xF83BE987)
NDIS.SYS Address F83BE987 base at F83A900, Datestamp 48025d03
I managed to boot the computer using an old version of UBCD4WIN (2008) and ran straight forward diagnostic and correction apps like chkdsk, and partition checking, ... and came up without any problems. There are other apps on the CD that I am not sure what they do, so I did not run them, but will gladly try if they are suggested. I do have another computer, obviously, that I can download any utilities to (including an updated UBCD4win) and put on CD or flash to use on problem computer.
I suffered a similar problem on a desk top a couple of years back, which has since been gathering dust. It is a Dell XPS 400, also running XP with SP2 I believe. I no longer have all of the specifics, but do remember the Blue Screen message was like: Driver IRQL LESS THEN OR NOT EQUAL TO ZERO. I did manage to get it to reboot on it's own, and before it re-crashed I tried to restore it to a version before the problem occurred. After that it died and wouldn't come up at all past the blue screen. I did not have or run UBCD4W apps on the desktop.
First I would like to try to fix the laptop, and if that works then the desktop.
