Random BSOD, help appreciated.

Hi, welcome to SF :) .
Thanks for activating Driver Verifier as it is pointing out an old driver.

Code:

Arguments:
Arg1: fffff9802d596f30, address trying to free
Arg2: fffff9802d596063, address where bits are corrupted
Arg3: 00000000008d40d8, (reserved)
Arg4: 0000000000000023, caller is freeing an address where nearby bytes within the same page have been corrupted

Let us now the results :) .

It's my pleasure :) .

The last two dumps are typical of Anti-Virus software drivers causing issues especially with DV enabled.

Code:

BugCheck C1, {fffff9801d3b8e80, fffff9801d3b8063, 6d4188, 23}

*** WARNING: Unable to verify timestamp for aswSP.SYS
*** ERROR: Module load completed but symbols could not be loaded for aswSP.SYS
Probably caused by : aswSP.SYS ( aswSP+c4a4 )

This driver is part of Avast, uninstall avast using Avast Uninstall Utility.
Install Microsoft Security Essentials as an alternative.


Keep this thread open for a couple of days to validate the stability of your system.
Then if all is well Disable Driver Verifier and mark it as solved .

Hi, that last dump didn't contain much except telling us that a driver caused a reference
count to drop below zero.

What settings did you use to enable Driver Verifier?
Driver Verifier will have false positives when set incorrectly.
If you want to be on the safe side you can test the RAM.

Test and Diagnose RAM Issues with Memtest86+:

• RAM - Test with Memtest86+

   Tip

• Pay close attention to part 3 of the tutorial "If you have errors"
• Test the RAM with Memtest86+ for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.

I asked you to install MSSE, but you installed AVG instead.

If you don't want to follow my advice then I have nothing I can do to help you anymore.
