I recently installed a Radeon x800 in an old socket A motherboard and it ran fine with the 400W power supply I was using. Wanting some more fps in Team Fortress 2 I moved it to a socket AM2 using the same power supply and randomly the screen would go black, sometimes causing a reboot, other times my desktop would come back but I would have no acceleration. I figured it wasn't getting enough juice thanks to the new cpu? So I've got a better psu coming in the mail.
However, I just decided to try it again since it was mostly fine with just desktop use, and as soon as I power on there's a red message flashing telling me connect the power supply to the graphics card(It is connected and I've tried 2 psu's). And when I remove the card to go back to onboard graphics I get a message along these lines at post, "Warning!!! The previous performance of overclocking is failed", and it restores the default settings, so is the card dead or is there anything I can do?
