Hi, I am currently having problems with Windows XP stability! the system
seems to crash at random frequently, usually during bootup, and occasionally
after the system has booted up…
I am having problems trying to pinpoint the source of the problem, upon
analysis of the crash dump file, WinDBG reports that there was a
SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION, probably caused by ntoskrnl.exe.
Which doesnt really make sense, I am wondering whether it could be possible
that my file system driver could be causing the problem, and the problem
isnt being detected until later on?
Is there anyone out there that could advise me how to root the source of the
this problem? I have tried the PoolTag utility, but i cant seem to locate
any tags created by my filesystem driver… is there something i must to
display my tags?
Regards
James Dunning
