Over the past week, I have experience 6 system crashes. Analysis of the minidump files all state that the crash was "probably caused by: aswTdi.sys ( aswTdi.sys+a59 ) ... Is anyone else having this problem? ...
Yes, I had it today. (Edit; sorry, should have said it bhappened when browsing, but using Firefox 3.5.3, not IEanything).The minidump mentioned aswsp.sys, rather than aswtdi.sys, by name (which made me suspect that Avast was implicated), but did not say it was probably the cause. What it said was:
Unable to load image aswSP.SYS, Win32 error 0n2
*** WARNING: Unable to verify timestamp for aswSP.SYS
*** ERROR: Module load completed but symbols could not be loaded for aswSP.SYS
Probably caused by : Pool_Corruption ( nt!ExDeferredFreePool+1f4 )
I switched on verbose output, which advised the use of driver verifier (which I had never used before). I set this up to verify all drivers on the PC and rebooted. This reproducibly gives a driver verifier BSOD without ever completing the boot process, and reports WDM driver error 224 in aswtdi.sys.
I'm using Win XP SP3 Home, Avast 4.8.1351, with VPS file version 091016-0.
I see we can submit minidumps by email for analysis but I haven't managed to find the email address on the support pages so far
