Random BSOD's, mainly ntoskrnl.exe but also other errors.

Code:

BugCheck 19, {21, fffffa800a615000, 1050, 50}

GetPointerFromAddress: unable to read from fffff80002eb1100
GetUlongFromAddress: unable to read from fffff80002eb11c0
GetUlongFromAddress: unable to read from fffff80002e1fa38
Probably caused by : memory_corruption ( nt!MmWaitForCacheManagerPrefetch+30 )

It seems that a driver has over run the data following the pool block being freed.

Code:

2: kd> !pool fffffa800a615000
Pool page fffffa800a615000 region is Nonpaged pool
GetUlongFromAddress: unable to read from fffff80002e1fa38
fffffa800a615000 is not a valid small pool allocation, checking large pool...
unable to get pool big page table - either wrong symbols or pool tagging is disabled
fffffa800a615000 is freed (or corrupt) pool
Bad allocation size @fffffa800a615000, zero is invalid

Run Driver Verifier to scan for any corrupted drivers which may be causing problems, this program works by running various stress tests on drivers, in order to produce a BSOD which will locate the driver; run for least 24 hours:

• Driver Verifier - Enable and Disable

Enable the Special Pool option too.

It could be the nVidia chipset drivers, which are well known to cause problems.

A Stop 0xA points to the graphics card driver:

Ok, I've enabled driver verifier now. Was a bit skeptic because the other times I've been asked to use driver verifier, I've had to make a system restore because I couldn't even get into safe mode. But now it seems it's working just as fine as without the verifier enabled. Will post the results after at least 24 hours of verifier enabled.

Approximately half-way into my 24 hours test I've got some things to report. The temps seem stable. The graphics card peaked at 53°C while playing wow. About 30-33 while idle and around 48-49 while gaming. I attached some screens of the temps. I also attached a few pics I took with my phone. It's what happens when it crashes. It doesn't go to a bsod very often at all, it's usually that screen that show. Just a blur of whatever color the last program i ran was. The few bsod's I've gotten hasen't created any .dmp files for some reason. However i wrote the cause down: one was because of Acpi.sys. Another did just show a stop-message: 0x01A (Memory Management)

EDIT: Can't for some reason upload my zip with the screens. Just get this error:
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

Have you tried again today? It may be something to do at this end.

Yup, I've tried a few times. Both to put them in a zip, and individually as .jpg. Still the same error.

Is your Internet working fine in general? I would suggest reporting the problem to one of the Admins - Windows 7 Help Forums - View Profile: Brink or Windows 7 Help Forums - View Profile: z3r010

Because I'm stupid and can't read the size limitations on .zip and .jpg for upload to the forum.. I tried to upload a file of 8.4mb when the maximum is 8mb. Anyways, it works now.

Anyways, the driver verifier has been enabled for more than 24 hours now. I've got nothing more to report than what I've already told you.

New sf again.
