Okay... a few weeks ago i decided to build my own system. My problem is when i boot it up the computer turns itself off after about 30 seconds. I get no beeps or anything on the boot up either. I have tried re-seating the processor and no luck.

Here is the general spec:

400W Power Supply
Socket 775 p4 2.8ghz 800mhz fsb
Abit AG8 Third Eye motherboard
512 DDR Ram
40Gb Ide Harddrive
X800Xt Radeon Pci-Express

I was also wondering if the computer turning off has anything to do with the Power connector to the motherboard. My PSU connector is 20pin and the motherboard has a 24pin slot although it does say it is compatible with a 20pin could it be causing the problem?

Thanks

From my experience heat and power supply failure causes a computer to shut off randomly. Also it could be the video card problem. How many case fans do you have, what kind of heat sink fan do you have and did u use a pad or thermal paste. Also it would be a good idea to check all the power/IDE etc connections to see if they are good to do.

Easiest thing is get someone in the know to look at it you cant solve alot of problems with so little info on a internet forum.

Yea they cpu shuts itself off when it gets too hot. Usually due to poor heatsink mounting
