Random BSODs during random tasks. Latest error: 0x1000007e

I am not overclocked. Running tests as prescribed. Will report back.

Alright, let us know if you need any help as you proceed with tests. Also, let us know if you find the cause. Best of luck!

Windows has finished checking your disk.
Please wait while your computer restarts.

Continuing on with tests as prescribed.

SeaTools Short Generic: passed. Would you still suggest that I complete the Long Generic?

Ran FurMark for 5-7 minutes. Leveled out between 65°C and 68°C. RealTemp reported slightly higher temps.

I would suggest you do the long generic test with SeaTools. The short can pass, and the long can fail, and vice versa.

The long generic test passed. Have had a few BSODs since then. Report attached.

Are you seeing any patterns in my reports? Certain things standing out? Initial diagnosis?

Nearly all crashes point to either your graphics card related drivers and installations / the graphics card itself or to your hard disk controllers / the hard disk itself.


Temperatures with Furmark looked good. Any artifacts on the screen?

Have you run the video memory tests, Prime95 test, the IntelBurn Test, or the Memtest86+ diagnostics?

Gotcha. No artifacts on the screen.

Running the Video Mem test now. Will run others overnight.

Do you see anything related to the additional 4GB of RAM that I added? Would you suggest a full system restore as a possible troubleshooting method (to rule out hardware)?
