I tried building a new computer but...

[subjugate]

Ok basically i bought all new parts and made sure they were compatable. I started putting the computer together and when it was done i turned it on and after about a minute-2 minutes it shut off. I kept trying and it kept shutting off. I finally disconnected each part and kept trying to turn it on with one less part connected and the same thing happened. Finally i had just the power supply and motherboard plugged in and it still shuts off. There are no loose screws on the motherboard so thats not shorting anything out. I have no idea whats wrong besides a faulty motherboard. I dont wanna buy another new one though. What do you guys think?

well, need full parts with make and exact model of everything to include:
RAM
PSU
GPU
CPU
HDD
etc..

Could be an overheating issue. Are you sure you have the CPU heatsink properly seated?

 

[subjugate]

yes as far as i know. I will double check that though.

You didn't tell us the power rating of your PSU. If it's faulty, or your new build requires more than it can supply, it would behave as you describe.

Yes, it still could be a short circuit. Try removing the screws holding the motherboard and temporarily insulating it from the chassis with a piece of plastic or cardboard, just to see if it starts up that way. If so, the board may have been just enough off center for some conductive area near a screw hole to short to the chassis.

Also, did you try reseating the vid card? Did you try a different vid card?

Good luck.

my PSU is more than efficient, its like 550 watts or something. I even tried another PSU. As for the video card, im using the on board video right now. That is fine, I ended up getting to windows start up at one point, but again it shut off. I dont quite understand what you mean about insulating it from the chassis with plastic/cardboard. Can you explain yourself more?

Sure. Sometimes, there are trace areas around the metal standoff's where the screws go. If you remove the screws, you can slightly elevate the board, and slip some kind of insulator under it. Paper, plastic or cardboard would do.

The idea is just to be sure there is no short between the board and the case.
