Dan's about to tell you about all the tiny bits n bobs you may well have lost by hoovering out your PC
Like these for example;
Little jumper blocks that will be all over your mobo, which dictate settings
Plus little rsistors etc that easily come off with a good bit of suction
Dan don't like hoovers in PC's. When I found this on ebay and posted it up (cos I thought it was a bit daft) he told me off
