So basically, playing my PC last night and it cut out. To describe it, it was like a power cut. But there was no power cut in my flat.
It kept attempting to turn back on, so I unplugged the power cable and re-plugged it back in.
Since then there's been no issues whatsoever (I even re-jigged all the wires inside and out to make sure and tidied it up a bit). Was it perhaps a loose cable?
More info:
1. My PSU has never over-heated (I touched the inside of the machine and read speedfan - my whole machine was cold when it went off and given I was playing an mmo if it had over-heated...)
2. Everything on the motherboard is fine, I can't see any overheating/popping etc on it.
Everything in the machine except the hdd and motherboard are basically brand new. Most of the common issues would mean the machine wouldn't have come back on..
Worrying over nothing perhaps?
