Hi,
The problem started a few days ago. I was playing Diablo 3 w/ Skype, nothing out of the ordinary, when my computer suddenly restarts. No BSOD, no warning or errors, just restarted. I thought it was weird but just re opened the game + Skype and tried again, same thing happened. I find this really strange because this has never happened before, not even while playing WoW with ultra settings. I opened SC2 and built a massive amount of units, nothing happened at first but as soon as I started another match the same thing happened. Let me tell you what I have tried so far: I put the PC under stress, I don't know if I did it right but the PC never restarted, just kept running. Tested the RAM, CPU and Video Card. I got frustrated and replaced the RAM (as a friend suggested), same thing happened again. I got even more frustrated and just formatted, downloaded the drivers, downloaded Diablo and tried again. About 20 mins ago the same problem happened.
I have no idea what to do. I can't test the PSU because I don't have another one. Please please for the love of god, help me with this, it's driving me insane.

might be your PSU Causing the issue, i had a similar issue with a Corsair PSU. My Pc would just reboot without no warning just like you, once replaced the issue never showed up again. Can't be certain though, check your temps and try another PSU. Good luck!
