(starts out with a gpu problem eventually gets to the mobo just hold on) Recently my radeon 7950 became corrupted and kept crashing so i sent it in for an rma where they replaced it with a 7970 with the same problem. I replaced the psu nothing fixed that, so i recently ordered a gtx 770 oc. When installing this card my computer would not boot so i switched back to my powerless gt 630 i had been using. That would not boot either. Upon closer inspection of the card i relized that my psu didn't have the right amp rails or whatever. BUT what worries me is that the gt 630 that requires NO power didn't work. Now everything is working fine but it worries me that it didn't work with the powerless card. Is it dying? What should i replace if anything?
