Well i thought my computer was fine but now i have another problem !! When ever i try to start my computer up it truns on for about 2 seconds and then shuts off. I tried leaving it on for a bit and nothing happened it just stayed off and then i kept turning it off and leaving it for a bit and then turning it back on and STILL nothing is happening(except for the 2 seconds of fans going around) it has been left off for the night but that shouldnt have aynthing to do with anyhitng should it?? MY power supply is 500watt so power isnt the problem.

Hello,
Well there are a few things that could cause your issue. The first one could be a bad powersupply. I realize you say it is 500W, but that doesn't mean it hasn't gone bad. I have had top notch powersupplies go bad in a month. Also, since I am unsure of the age of your motherboard, I'll mention that a couple years ago motherboards were susceptable to capacitors leaking which shows that symptom. If you look at the capactors around or near the CPU and where the powersupply connects to the motherboard it is easy to spot. They will either be buldging or leaking, therefore a bad motherboard. Another thing to look at is, did you forget to plug in your CPU fan or accidentally knock the wire off the connector? If you have an AMD CPU it doesn't take much for it to shut down since they get very hot. The last thing is a video card, however, your symptoms probably point to the other 3 issues moreso then a video problem.
Hope this helps,
Jason

Whenever I a wondering if a P/S is bad, I take a couple of old CDROM's or hard drives and plug them into it. I then completly disconnect it from everything else including the wall. On the main connector that was running to the motherboard, take a piece of wire and short pins 14 and 15 (green and the black next to it) and then plug the P/S in and turn on the switch if it has one on it. If it runs fine, chances are it is o.k., if not you have probably found your culprit. If you have a multimeter then you can also easily check voltages.
