DRIVER_CORRUPTED_EXPOOL (c5)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is
caused by drivers that have corrupted the system pool. Run the driver
verifier against any new (or suspect) drivers, and if that doesn’t turn up
the culprit, then use gflags to enable special pool.
Arguments:
Arg1: 00000000, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: 8054ba39, address which referenced memory

SnowSurfer: send us your minidump to vlk@asw.cz… thanks

7

Thanks
Vlk

8

ok i sent all of them pertaining to aswmon2.sys

9

imagine that, now i cant get it to crash.

10

Helo! I am new in the forum. I had also bsod and in the bsod it was referred that the stop was in the aswmon2.sys. I have the same version of AVAST (4.5.549). I would appreciate your help about what happened. When the crash happened i wass listening to music in winamp. How can i send to you the dump files?
Thanks in advance!

11

Send couple of the latest *.dmp files to vlk@asw.cz. Thanks.

12

Ok i sent the latest dump files! Thanks again.

i fixed my crashes…believe it or not this is what i did (im not sure which step fixed it though)

I installed new ram in my machine…no crashes
I installed a new power supply…no crashes
I switched to Sygate Pro instead of Outpost Pro, no crashes

so I dunno what was the problem but it was one of those things (apparently :))

14

I recently installed a new powersupply at 420 watts. I use the ZoneAlarm as firewall and i have tested the memory for errors (with the memetest utility) and didn’t find anythig wrong as long as i tested. So i am waititng the results from the review of the dumpfiles. I beleive that the solution is there
:slight_smile:

15

im sure there is a solution there, the memory I had scored no errors on memtest also, i just dont think it was compatible with my motherboard
