As for chkdsk /r, I can try it, but I have already run Dell's desk error checking program as part or several extensive diagnostics that I have already run.
Too bad it froze again
About overheating... I have both W7 and W8 on the computer. It works on W7, but freezes on W8. It must be something else (I've also tried apps that place heavy load on the CPU and the GPU and I've gotten very high temperatures, without problems).
By the way: I just saw that there was a new GPU driver on Windows Update (released just a couple of days ago).
Did you check for a minidump folder in C:\Windows
Maybe it made one and did not reboot because you set it not to, like zigzag's post said.
I'm running chkdsk but it's taking its time. It has been on 27% for the last half hour or so. It hasn't frozen yet because the animation is still playing...
OK, I walked away from the laptop for a while and when I came back, I was at my lock screen. No indication that anything went wrong so I guess we can rule out a disk problem.
I wonder if it would freeze (while being actively used) in safe mode... and if it will ever freeze if just left alone, without use.
I'll try it in safe mode. If it freezes then, I've got problems...
Secretly, I'm hoping that it is a hardware issue, because if I can convince Best Buy that it is a deep hardware issue (something with the motherboard, CPU, etc) then I will get my device replaced with a newer model with similar specs....
