I went over to my neighbors to work on his moms comptuer because Norton was messing up something or other. So i also looked at his old one that he claims Staples blew his motherboard up. he says it powers on then instantly powers off i guess. Im thinking its more towards a PSU issue. Since its a LGA775 system with a micro atx board i think it would be easier to just replace the PSU if at all possible, since LGA775 boards are hard to find now for a decent price. Does this sound like a PSU issue. it has a generic Cooler Master PSU.
