Hi sammyandsam.
You described a PAGE_NOT_ZERO BSOD, which is stop 0x127. It is .....
Code:
PAGE_NOT_ZERO (127) This bugcheck indicates that a page that should have been filled with zero was not. Typically this is due to a hardware error or some privileged component modified a page after freeing it.
Whereas, the attached minidump says something different, a KERNEL_SECURITY_CHECK_FAILURE (0x139); which is ....
Code:
KERNEL_SECURITY_CHECK_FAILURE (139) A kernel component has corrupted a critical data structure. The corruption could potentially allow a malicious user to gain control of this machine.
So there is a versatility of the bugcheck codes.
I would suggest you to do the following:
Scan the system for possible virus infection with the following programs.
- Anti-rootkit utility TDSSKiller
- Windows Defender Offline
Test your RAM modules for possible errors.How to Test and Diagnose RAM Issues with Memtest86+
Run memtest86+ for at least 8 consecutive passes.
If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.
Stress test the Graphics Card using Furmark.Video Card - Stress Test with Furmark
