System restarts

[Mark]

My PC has started to re-boot sporadically. It can be fine
for hours but then just re-boots. Initially it came up with
an LSA Shell (Export Version) error message but that
doesn't happen anymore. I sent the report to Microsoft and
it implied it was a driver problem. I have not added new
harware or software recently. Other searches suggest a
sasser worm. I have used the symantec stinger tool and my
system is clean. I run, adaware, spysweeper, F secure anti
virus, and the XP firewall. I installed XP2 a month or so
ago and had no problems. Any help or guidance? I have
scheduled a chkdsk at next boot up and disabled automatic
boot-up to get an error report. I am lost.....and don't
wish to re-install XP
thanks
Mark

Mark, I don't have an answer - I'm looking for one myself. My computer is
doing the same thing - shutting down and restarting itself. Get error
report, connect to internet, send report. Says it's a device driver, but no
further information available when I track. Also getting explorer.exe errors
- can't even track those, only got to send report once - my entire computer
locks up. Have done the same as you - scanned with McAfee, Panda, Spybot,
ad-aware, CWshredder, Stinger and the Microsoft sasser detection tool -
NOTHING found. Only hardware - scanner; uninstalled, used hardware wiz to
reinstall, says it's working fine. So I don't know what to think is going on
either. here's hoping we get an answer!

I did a chkdsk - no problems. Turned off auto reboot and so
got an error report : Page Fault in Nonpaged Area with a
Stop report 0x00000050 (and four more in brackets). Here is
a suggestion I found - which doesn't help resolve the
problem: The Non-Paged area is that area of RAM which
contains the system core code. Since this code is unlikely
to contain errors a'Page Fault in Non-Paged area' likely
indicates a serious problem with RAM. It might also be
faulty code put there by a damaged hard disk.
So - where from here?
Thanks

I had also desperate times with rebooting XP (SP2 espceially).
Error information was mostly coming from display driver.

but then I created boot diskette for MemTest86 tool and boot from it and
*zadam*, my 3rd memory stick (sdram) reported errors.
That memory stick address started from memory > 430MB so it
in normal use (low load) it was not used. (my own theory).
I took bad memory way and everything started to work much better.

Yes. Defective RAM is one of the possible causes of errors.

The important things to do are to:

1. Turn off the "automatically restart" in Control Panel - System -
Advanced - Startup and Recovery Settings.
2. Research the actual cause of the STOP, starting with MVP Jim

Good luck
