Installed new power supply, booting problems

[Deganveran]

I've been checking my connections but, since I change PSUs so rarely I am not sure if I am missing something. I have an OCZ fatal1ty 550 watt. I have a XFX Radeon 6970, an intel 3.20 ghz dual core, a 120 mm and 80 mm fan, a DVD writer/drive and an hard drive.

The computer starts up, I head the fans spin up and lights light up but nothing shows on the monitor. The computer stays on for a few seconds before it shuts itself down, pauses for a few more seconds and tries to start up again.

Can anyone tell me what this can be and how I can fix this?

Just checking, do you have the 6-pin PCIE plugged into the video card?

CPU connection

The psu is connected to:
4 prongs to the CPU, the bar-like power to the motherboard, and 8 and 6 pin into the mother board, sata into the hard drive and DVD drive, another 4 pin into the hard drive. Those are the connections I have.

I also switched back to my 4850 video card to make sure it wasn't a non-enough wattage problem.

When it tries to start up again, does it work the second time or does it do the same thing? If it doesn't, it sounds like you might have a short somewhere...

It just keeps trying to start itself up. I am going to try re-installing my old psu to see if that makes it work.

Sounds like a short. I would check the wiring...

I had to fix a friend's computer recently that was exhibiting similar symptoms. PSU and mobo were fine. Turned out it was a faulty RAM module. Try booting with just one stick of memory, then the other.

I think it was a ram seating problem. I have one module in right now and the computer is working, I hear the fans going and I see the lights inside the case. The problem now is nothing is showing up on the monitor. I have it plugged in but the monitor is completely blank.

Edit: It started working again. Thanks for your help everyone!
