Can anyone tell me what would make my computer kick me out of games that it shouldn't (I.E. Half Life, BF1942, Star Wars Galaxies, etc) and sometimes restart my computer? I just did a complete format the other night, two in fact. I have all the updated drivers for all my software / hardware. I don't know if this would have anything to do with it, but after I installed a new power supply, all this started to happen. I've run countless tests on my RAM, and my video card, so I doubt it can be either one.
