System shut down.

[trigger_andy]

Hey, OK I have a major problem with my PC just now. When I hit the power up button on the front of the case the system will start to power up, the fan's kick in but after a second or two the whole lot shuts down. The MoBo (ASUS) still has its green power light but when I go to hit the power up button again nothing happens. I have to wait a while, maybe turn the power off and drain the residual power before it will kick-in and the repeat the above proccess. I'm running Vista 64, ASUS MoBo, XFX 7900gt. 4800AM2 Dual Core and 2 gig of generic RAM. Any help would be much appreciated.

Hi Andy,

Welcome to the forum.

This can be caused by a number of things.

It sounds like it could be a overheating issue with your CPU. Double check to make sure that the CPU fan is running and properly mounted.

If this checks out, then you could have a bad PSU (Power Supply).

I would strip the computer motherboard down to the very basics and add until you find the problem.

Hope you find the problem,
Shawn

yep do whtever Shawn has said. I suspect its a Power issue.
Have you connected the PCI-E Power cord to 7900GT ?

Cheers guy's! I appreciate it. I have taken your advice and looked into the power supply. Turns out my 450 Watt is not up to the job and nor is it a ATX v2.01 so I have gone out and bought a nice 650watt.

Cheers,
Guy's
