PC restarting during boot (Cold Boot only)

November 30, 2012 1:57:17 PM

Hi all.

PC is acting really weird, during a cold boot it will 99% of the time restart itself once or twice.
Today I got past the login screen to the desktop for 5 seconds then it restarted.

All is fine after that.

My hardware has been the same for 3 years now but I've only just upgraded the RAM, added an SSD & a replacement video card.
Tested the ram with memtest and its fine, thought it was the OCZ ssd but it died a few weeks ago anyway & the problem still persists.

My AMD Phenom II is overclocked with a corsair H50, but its been OCd for over a year now with no problem.

I've had a few times where the system has rebooted during the day hours after i started it.

Has to be either the PSU or mobo. My PSU was clicking randomly when using the PC but It has stopped, could be something wrong with the capacitors inside?

Any way to be sure?
