My PC has been rebooting itself for a few weeks and I've been putting it down to overheating CPU, so I've got a new CPU cooler to solve the problem. However the PC continues to randomly shutdown and reboot itself when all the temps are normal (CPU, Mobo, GPU). One difference between now and before I changed the CPU cooler is that the reboots used to get stuck in a rebootloop and never able to restart itself. BUT post-cooler it is able to restart itself perfectly fine. However, it also reboots less frequently without the sidepanel on...

So my Q is, is this a voltage issue or what could it be? overheating other parts?

GPU- ASUS GTX770
Mobo- ASUS Maximus VII Hero
CPU- i5 4690
PSU- Corsair RM850

I thought that to begin with myself! So I got a replacement from Amazon but the problem persist.

I'll try the memtest right now, also I forgot to mention, this occurs only when I'm ingame. Don't think it has happened when Im just web browsing

I have finished with the memtest, did 26 passes without problem so I assume it's ok? For Furmark which test shall I do? Burn-in test/Burn-in benchmark test?

Ok it's been 2 weeks since this was "solved" or so I thought, I sent my 770 off for a replacement and they confirm that it is indeed overheating so I'm still waiting on a replacement. For the past week or so I've been using my friends old 560 as a temp measure, it worked perfectly fine for a week but 2 days ago it started to restart itself sometimes when in game just like before. Anyone know whats up?
