BSOD when system is under heavy workload

Hi krfuge.

Checked 4 of your latest BSODs. One is stop 0xA; two are stop 0x3B and one is stop 0x124.
So it gives a mixed impression overall.

Anyway, avast is contributing to the BSODs.

Code:

fffff880`06e4c498  fffff880`045b4940Unable to load image \SystemRoot\System32\Drivers\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
 aswSP+0x2f940

Description here: Driver Reference Table - aswSP.SYS

Uninstall Avast using Avast Uninstall Utility. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

And the display driver, too.

Code:

fffff880`06e4c318  fffff880`058ef7eaUnable to load image \SystemRoot\system32\DRIVERS\nvlddmkm.sys, Win32 error 0n2
