Last week I purchased a new Video Card (EVGA GeForce GTX 460) and thus needed a new PSU (Corsair TX750). Everything has been going fine, PC is/was running great.
So today while I am working, all of a sudden the PC power shuts down. Not the Windows shut down, but like a instant cold power off. This actually happened a few days ago, and I thought I may have hit the power surge switch with the edge of my foot so I thought nothing of it. Today, when it happened again, I knew something was up.
My first thought was that the 750 was dead, even though it was only a week old. So, I unplugged everything except the 24pin to see if the PC would stay on. Light on the board is green. Turn on power, nothing. One second of my fans and PSU fans spinning, then it tries to start again. This happened over and over until I decided to unplug and power off everything.
I took my older 550W PSU and put it in the rig. Plugged the 24 pin in, and same thing. Cycles for a few seconds and then nothing. I unplugged all the fans, SATAs, video card, etc to where it was just the PSU and the board. Still nothing. Only green light on the board and 1 sec of spinning fans
So...I can safely say its not the PSU (even changed the power cord, unplugged from power surge, and plugged into different electirical socket). So I "THINK" the only other two solutoins would be the Mobo or the CPU. Either way I have no clue how to determine which one it could be and kinda upset that something from the new PSU or GPU could have done it. My third random thought is that the power switch is shorting out???
Computer Hardware and O/S
Motherboard: ASUS P5K-e
CPU: Intel Core 2 Quad Q9300 2.5GHz
PSU: CORSAIR CMPSU-750TX

If we think the Mobo is dead (My new #1 thought) any suggesions to work on the specs above.
Thanks in advance,
