I have a M4A88TD-V EVO/USB3 motherboard. I have an ATI video card in the first slot when I power the PC the monitor does not detect a source and will not come out of sleep mode. The fans seem to go up to 100% power, and become very loud very quickly. However, when I put the video card in the 2nd PCI-E slot, I get video and windows boots up and everything works as it should, normal operations, no BSODs, no random shut downs, performance is good and as expected. Is it possible for a single PCI-E slot to go bad? What could be the possible cause and if it repairable?
