well luckily me and jcs live close to overclockers so we can go straight to the shop. we tried everything to sort her pc. power supply, audio drivers (which seem to keep showing a BSOD from time to time.) graphics drivers, memory test, and updating the bios. nothing seems to have worked. any one got any suggestions on what else we can try. we cant put another gfx card in to test as we dont have a spare lying around atm, unless i take the one out of my pc to try out.
