I'm a bit puzzled. I had a PSU problem couple of months back -- it won't power on and when it did, it went into power on/off bootloop (turned on for 2 seconds and turned off, repeat). So, I contacted XFX and went through the RMA process. 8 weeks later, got a replacement new PSU (XTR 650W 80plus Gold) and it worked straight away after the installation. But then, after about half an hour, it started acting up and went in the power on/off bootloop again!

So, I completed took the whole system apart, dusted and put it all back together, and now it won't power on. The PSU is a brand new one so highly unlikely to have gone wrong -- could it be the motherboard? Or the case -- I mean the thin cables connecting the power button to the motherboard, they could also break, right?

Any ideas?
