Hi All

My system is as follows:

Asus A8N-SLI Motherboard
AMD 4200+ X2
2Gib Corsair Value Select
7800GTX
160Gib Hard Drive
Linksys Wireless Card
Corsair 400CX PSU

The problem is my PC randomly turns off will not turn back on. The power supply is a recent replacement for one that failed, so I checked I had plugged everything in ok, but my PC wouldn't turn back on. But after some experimentation and trial and error, I have found that after the power button is pressed, if i move the wires that go into the PSU to a certain angle the PC turns on and starts up until it randomly turns off again. Sometimes it turns off regularly a few times in succession others it can be more than a day.

My question is should I RMA the PSU knowing that the problem might not be reproducible, or is there something I could do that might fix the issue.

Many Thanks

Andy
