While playing games with said HD7870, my system has begun to restart itself, no error message just cuts out then reboots. At first I thought it was the processor overheating however the temperatures never
exceed 70C on load.
I ran 'MdSched.exe', but no faults were found with the RAM.
So I decided to switch out, back to my old HD5770 and after somewhat extensive
replaying on my old GPU the problem did not present itself. I then changed back
to the 7870 and the problem returned, I tried adjusting the fans to 100% to rule
out overheating as a cause but still the problem presented itself.
By process of elimination I'm assuming it's the power supply/GPU relationship, however from what I can tell it's got the 7870 covered in regards to both wattage requirements and amperage, so I'm not sure why.
Could it be motherboard related in any way, or am I just being stupid?
Any help is appreciated as I'm stumped. Thank you for your time.
P.S. Sorry if this is posted in the wrong subforum
