A while back I would start my pc and it would work for around 2 mins until it would randomly die. It kept getting quicker and quicker, so I replaced the PSU from 700w to 780w. Didnt fix it. So i bought a new mobo from an Asus p5k deluxe to a new gigabyte ep45-ud3p. Still shutting down. I have vista 64 and I've only got to actual desktop once before it died. I have an Intel Quad Core CPU that might be the case. Any ideas? I've reset the cmos, checked cords, damn near everyhting ,but swaped CPU.

LOL triple post.
Try removeing the memory and power it up if it gives a long beep that means the motherboard is working try useing one stick at a time. And in the future try not to post more then once
