Power Problems :( Help?

post #1 of 6
Thread Starter 
So I turned on my computer today and I was using it for about 5 minutes. After 5 minutes... it turned off and started back up automatically.

So I decided to check things to see if my heatsink was seated properly... so I put new thermal paste on.. reseated.... and then it turned on for a bit and it displayed a screen saying a new CPU has been found... press so and so to load default or go to setup..... then the power died again... and now then it automatically turned back on again..

So I decided to leave it bee... Now I can't turn it on. When I try to turn it on.. the power flickers on and automatically turns off within half a second.

I tried to take everything out and put it back together and made sure all the wires go to where they are suppose to go.. but after I did everything agian.. same thing..

what is wrong with my computer?

thanks

Do you have a 750W Corsair, or an Antec? Your sig rig says that you have the 750W TruePower New.

Regardless, how long have you had the PSU?
It's a computer!

Like others have suggested, I'd see if you can get a hold of another Power Supply to swap and test with. If the problem still persists, I'd test the components out of the case to make sure nothing behind the motherboard is causing a short. It's easy to do. I just use my coffee table covered with card board. Put your motherboard on it and just connect up the bare minimum of parts needed to get it running, - one stick of RAM, HDD, and graphics card.

This may sound stupid, but is your power supply fan running when you turn the computer on? I had that same exact problem only to discover my psu was overheating. It's either a component getting too hot, or the psu going bad.
