I could really use some help with this.... Friend of mine got a Antech 650w with two pci-e connectors. k the weird part, put it in worked fine. about 6 days later, stopped working. He exchanged it for new one, he brought it over i put it in, started right up. get all the plugs hooked up turn it on again, nothin. tried it in my computer, worked fine. Tried my Power supply in his computer, worked fine. now he has a dual core processor with a somewhat generic motherboard. The Only thing i could think of is the motherboard just being generic and not being good enough? but doesn't make sense is that it worked fine for 6 days already. Any help or suggestions welcome PLease
