Hi, I think i have a problem with my psu maybe? I reported on here a couple of weeks ago about my computer just randomly switching off a few times. Well since then it never happened again. Today however, when i first switched on my pc, it came on for about half a second then went dead, i tried turning it back on but it wouldnt. I had a spare psu, so i tried that one on my computer. This one did turn the computer on, however it seemed to be caught up in a 2-3 second loop and nothing came up on the screen. I swapped back to the original psu, and my computer worked first time again. I was wondering if anyone else has had a similar problem and did it turn out to be psu related? Thanks again, Phil.
