I'm convinced it's a problem with the computer and not the house, like I said my housemate's computer doesn't suffer from the same problem, and I'm becoming more sure that it's graphics card related as I can have the computer on for hours with no problem, but as soon as I load up a game like championship manager or rollercoaster tycoon it blows after 5 mins.
Having said that I don't know half as much about computers as I'm sure you guys do, so if I'm talking piffle do feel free to tell me to shut up
thanks for all the input so far though guys, it is appreciated.
