Sometimes it's twice a day. Every time I come back to my computer and find that it's on the login screen, I know that it crashed and rebooted. I think there could be some connection to the USB subsystem. Often times, my keyboard won't work after a crash, and I'll have to plug it into different USB port to get it to work.

Below are links to the most recent minidump files. While the parameters may differ each time, it's always the same driver (ntoskrnl.exe) and the same crash address (ntoskrnl.exe+150ca0).

The driver verifier didn't detect anything, and neither did Memtest+.

Do the minidump files not indicate which specific driver was the cause of the crashes?

CB

What did sfc say at the end?

Did you run DISM?

Did memtest find ANY errors?

The DMPS pointed to memory corruption as I said.

Old drivers
