Just another update on the issue. The crashes still happen at random. I set my stock clocks back to normal. Temperatures never fall out of range as I'm looking at HWmonitor. My friend suggested that it could be the chipsets or the VRM (cylinder type capacitors) are over heating on the mother board.
I have an Asrock M3A770DE motherboard, haven't had issues since I've had the system for a couple of years.
Sometimes after the crash while playing D3, I try to reopen D3 and it will reject. I try to open Chrome as my browser and it will reject the opening, stating my settings were corrupt.
Is there some issue or corruption anyone has dealt with? I heard it's very hard to track and I might need to reformat =\.
