[z-tune-2]

Hey, I'm new here and I'm in dire need of some help!

I have a dual core 2.8ghz processor (not sure about anything else on it, I got it from a pre built comp), 2 gigs of corsair PC2- 5400 675 mhz ram and a 500 watt PSU.

I have everything plugged in and I get the whole continuous reboot jazz...

I played with the ram, one stick rather than two, tried using different slots all combinations and no luck.

I then unplugged the 12v CPU cable and it stopped rebooting, but it also didnt post.

I'm not hot on computers at all, I just managed to build one but the mobo died (dodgy line of Asus P5K boards) so I swapped to this one and accidently opened a new can of worms...

Does anyone have a clue what it could be?

The computer doesnt even post, never, not once. I've left it cycling through the reboot process for 5 minutes straight. It fires up, 3 seconds later it reboots. Its doing my head in!
