Case fans spin for 1 second then stop, no boot HELP!!!
Hi I just built a new gaming computer on thanksgiving and it worked fine until now. So about 1 month. On occasion it would shut down by itself, like it lost power, but the monitor would continue to have power and its on the same power strip.
I was thinking that something isn't grounded properly as it's setting off the psu protection where I have to flip the power supply switch before I can again hit start and have it spin for 1 second. Video Card, Case, and PSU fans all spin for 1 second.
I took the power supply out of the case, reseated the heatsink, moved the ram to different slots. Nothing has worked. Could this be a bad piece of RAM, cpu, or psu?
Components
q6600 G0 stock
Gigabyte GA-EP45-UD3P
TRUE heatsink
4 gig corsair generic ram
wd 640gb black
evga 260gtx 216 vanilla
corsair 520hx
The only thing I can think to try now is take components from my internet computer and replace cpu, psu, motherboard, or ram to see if one is faulty?
Would one of these components being bad cause this kind of problem?
I would appreciate any suggestions you could give because I really hate to have to take this working computer apart in hopes of finding what is going on with the other one.

I recently had exactly the same problem with a low power file server. I swapped out everything except the board and CPU. So i presumed it was the board that was faulty.
You can test any PSU without plugging it into a board using a paper clip, does the PSU stay on then?
Eventually i worked out what my problem was and a cheap solution.
I made a paper washer ring for each screw holding the board to the case, then slid a piece of paper behind to completely seperate the motherboard from the case. Obviously it was being short circuited somewhere. Now it works fine.

Update:
I taped a piece of paper behind the motherboard and reinstalled everything and it works! So I guess it was shorting out.
Unfortunately now it has developed a new problem. Every 2-3 seconds the mouse stutters. This is consistent, it is happening exactly every 2-3 seconds. The sound seemed to stutter some too. Any ideas?

I think you have some issues there. You may want to investigate RMA'ing that board. If you've properly secured your motherboard to the case using stand-offs and the ATX connector is securely connected, you should not have any shorts. Also, check you case (particularly the USB connectors) to make sure they are grounded. I've seen some people short out their mobo with a bad USB connector.
Update:
After putting the paper behind the motherboard it seems to be fine. The motherboard has a metal bar on the back to hold on the north bridge, and I also had a back plate for my TRUE. I wrapped the back plate of the TRUE with electric tape but I don't think that was the problem.
Also noteworthy the TRUE was loose so I put a rubber washer between the retention mechanism and heat sink to tighten it up. (It dropped temps about 6 degrees!) But it also makes the motherboard curve ever so slightly. I think that because the board was slightly warped the north bridge bar was shorting on the case.
The mouse stopped skipping after a reboot. I had booted with "Last good settings" and I think I had an IRQ conflict or something because I changed the SATA plug for my hard drive.
As of now its fine. No crashing. Unless noted otherwise it's cured.
Hopefully the paper behind the motherboard won't catch fire or anything.
