Hi - I have a Win7x64 PC that is starting to show random STOP 0x9F BSODs.
The failures can occur at any time, sometimes during shutdown. The PC will hang (no mouse movement, or screen updates), but there will still be periodic hard drive accesses. The system may hang for a half-hour or so until I see the BSOD appear.
Could this be RAM related? I have new RAM (about a month old). While Prime95 tests OK without failures, I do see some odd stuff from OCCT where my CPU temperature sensors go to 0 after a few minutes then suddenly go to 127. (However, this may not be related at all - I think this is a bug in OCCT that is not compatible with my Asus Sabertooth Z77 motherboard - but, I thought I should mention it).
I can post my DMP file if someone can help me with this.
