I have a really strange problem. A friend of mine started having problems turning the pc on. The pc was turning on for one split second and then off. Had to take power cable out and put it back to be able to get any electricity to the motherboard (led). Same problem again if I was trying to turn it on. So I thought it was a short somewhere so I took the motherboard out and let only minimum components and try to turn it on. Same problem. I took my PSU(2) and tested his rig without and with all his components and worked fine. Took his PSU(1) and put it on a different rig(4), worked fine. Now, maybe something had a similar problem and explains me where is the problem and why. I tend to believe is PSU is to blame, probably it's preparing to "die".
1. His PSU - OCZ 680W
2. Mine PSU - Hiper 880W
3. His rig : Abit IP35, Intel Q6600, 2 x 1 DDR2 800, 8800 GTS, one hdd and one dvd-rw
4. The rig where I've tested his PSU - Abit AB9, Intel E8200, 1 x 1 DDR2 667
Swap power cords only. If that doesn't work, new PSU.

Unless you are running some kind of awesome GPU setup, that should be more than enough to handle that rig.
@totalknowledge: Not really. It can be also a short somewhere. Not in my case of course. Have tested the rig outside the case on a wood table.
I (in my myopic 20 years dealing with my, my work , and my family and friends computers) have never seen that specific behavior caused by a non-psu related short. It has always been caused by a faulty psu. Not to say its not possible, but I don't think that that would be a common cause or the computer not starting, and then starting after unplugging the power supply, then plugging it back in.

I have seen it several times. Not that I have 20years to my belt.
Thanks Novuake but I didn't have time to enjoy it. I received the psu yesterday. Installed it on my system, worked for few seconds, windows booted and BANG. A loud noise came from my pc and the house fuse went off. Luckily it was only the psu and nothing else. Checked the pc with a different psu and the motherboard's led is working so seems to be fine. Now I have to send the psu back.
