I've recently been having a number of issues after upgrading to Windows 8.1. I've formatted my drive and reinstalled 8.1 twice now and still have similar issues. Most of the time I'll wake up and my computer will have restarted overnight, but every now and then it will restart while I'm using it.
At first I thought it might be an issue with my memory modules, so I swapped the 3*2gb modules I used for ones I knew were good. The issues still persist. At this point I think it's a driver issue. This computer is 6-7 years old but other than these blue screens runs fine. I have no issues running Linux distributions, which reinforces my feeling that it's not a hardware issue.
I'm really not sure. I uploaded the 5 minidumps generated from the 5 crashes since I last reinstalled 8.1 If any of you can take a look at these and make sense of the issue, I'd greatly appreciate it.
