Hey all, I'm a first time poster but have been reading this forum for years.
I'm having trouble isolating a likely hardware problem causing random reboots of my PC.
A couple of weeks ago my PC started rebooting randomly, this could happen once every few minutes or it could be hours between reboots. It started happening in Windows 8 but a reformat didn't help and the problem also happens in Windows 7 and Ubuntu. There is no hang or freeze, it just reboots even while the computer is idle.
I thought it might be a hard drive issue so I loaded BIOS and left it there and it still rebooted.
I replaced the graphics cards with another one I had lying around and that didn't seem to fix the issue either.
The CPU temperature looks fine, it's running at 25-30 degrees on a dedicated 3 radiator water cooling loop. It was overclocked but I also tried restoring factory clocks and turning off turbo.
Memtest didn't find a problems with the memory.
I think the PSU is to blame as that is the oldest component in my build. But replacing it would be quite a laborious task and before I do that I want to be sure that it isn't my memory, CPU or motherboard.
Has anyone experienced this issue before? How would I go about isolating the faulty part?
Hardware:
CPU: i7 2600k @ 5Ghz
RAM: 2 x Corsair Vengeance 4GB
Graphics: 2 x HD6970
Hard Drives: 2 x OCZ Agility 3 SSD and 2x WD Caviar Black
PSU: Silverstone 750W (Five years old but 100,000 hours MTBF)
Thanks in advance.
Andy
