Hi all, Anyone come across something like this before? My thoughts are PSU but I don't have one powerful enough handy to test with so would like to be sure before buying another.. (Plus its a corsair so I expected it to last!!!) Symptoms: PC restarts itself. This happens even in the BIOS screen so nothing to do with software. First I thought it was GPU or CPU OC so these are back to default clocks. It happens at random times, sometimes after 30mins - 1 hour, sometimes it will happen 10 times in a row before the machine can even boot into Windows (or just sat in BIOS). Temperatures are normal. Specs 2500k Corsair TX650 MSI Z68 board 8gb corsair vengeance crucial m4 ssd. Thanks!
