Computer Boots up then shuts down

by HolidayTech - 7/19/10 4:31 PM

I have just made my self a new computer and everything went fine until l started it up what happens is that it starts up and all the fans start spinning and nothing come up on the screen and then after 5 seconds it will switch off and start up again. So I started unplugging cables inside the computer in an attempt to fix it and I unplugged the graphics card and the time between the computer booting then shutting down increased to about 15 seconds so I though it was the PSU the was not powerful enough to power my system but when I got a spare PSU which is 450W it still did not start with only two 120mm fans, the motherboard and a CPU plugged into to the PSU. So I now have no idea what is wrong any help would be great. I just wanted to say unlike similar questions I can not even get to the POST screen the screen is completely blank.

PC Specs.

Intel i3-530 with stock cooler
Gigabyte GA-H55M-UD2H
Radeon HD 5770
4gb corsair
400w corsair PSU
Seagate barracuda 7200.12
Two 120mm fans

If you need any more details please ask.
