Well, i don't think they would have sold him a pre-built computer without an adequite power supply, so i don't think it could have been overloaded.

Just search the motherboard for burnt areas or blown capacitors, if not then it was your PSU.

ah ok, mind doing me a favour? take the side of your computer off and look at your power supply unit, mind reading the label on the side of it stating the vottage and make / model?

as this will help us tell if its definately your PSU thats blew up.

The label is on the underside of the psu and my psu is at the bottom of my case.

yeah but i changed cases to a one with more fans in - they thought that might have been the problem when my gpu was messed up.
