BSOD Help please


I keep getting bsods a few times a day now and end up with this error code after i did the verified drivers stress test, when i was running the test my computer would blue screen just b4 the login everytime so im guessing its a driver issue of some sort.

STOP 0x000000C9 (0x000000000000023E, 0xFFFFF880011A5360, 0xFFFFFA800F14CEE0, 0x00000000000000000

The pool is already corrupt at the time of the current request.
This may or may not be due to the caller.
The internal pool links must be walked to figure out a possible cause of
the problem, and then special pool applied to the suspect tags or the driver
verifier to a suspect driver.
Arg1: 0000000000000003, the pool freelist is corrupt.
Arg2: fffff8a0188b1bc0, the pool entry being checked.
Arg3: fffff8a0188b1bc0, the read back flink freelist value (should be the same as 2).
Arg4: c6fff8a0188b1bc0, the read back blink freelist value (should be the same as 2).

Use !analyze -v to get detailed debugging information.

thanks for posting the info. You have dump files ranging from Bugcheck 3B, Bugcheck 1A, Pool corruption and Bugcheck 24 NTFS. The dump files for memory errors far outweigh anything else and it could be that you have some faulty RAM.

BiosVersion = F5
BiosReleaseDate = 05/16/2013
SystemManufacturer = Gigabyte Technology Co., Ltd.
SystemProductName = Z87X-UD3H
You have Bios updates pending. Please update ensuring you have the correct download for your motherboard:

You'll notice the above dump file is blaming this file:
aswSP.sys Mon May 05 09:11:11 2014: This is Avast AV and is known on occasion to cause issues. Please uninstall and use MSE as it's far more stable:

dtsoftbus01.sys Thu Jun 20 08:22:51 2013: Daemon Tools driver. Possible BSOD issues in Win7 uninstall to test.

You do really need to update some drivers namely:
SiRemFil.sys Wed Jun 20 20:42:10 2007: Silicon systems?
DC3410.sys Mon May 02 10:37:16 2011: DC-3410 RAID Controller?
I couldn't really find any further info on the above
mv91xx.sys Thu Jun 16 10:50:48 2011: Marvell MV91xx AHCI/RAID driver. The driver for this is one the motherboard page. Please install the latest updates:

If after updating the above your still getting bsod's then download the latest version of memtest86 here:
This guide although a tad old will show you how best to run it:


Ok i have Done all the above and i ran a verify on my drivers no blue screen anymore (so hopefully we hit it on the head) i cleared my dmp logs and will be trialing over the next few days if i get more blue screens ill post back here with the logs :D! thanks
