Got a new case so I pulled everything out and reinstalled into the new one but my gtx 770 is not working. If I put it into pcie slot 2 I get message saying needs to be in one but in 1 the screen doesn't turn on. Tried an old card in one and it goes on so at a loss as to why it's not wokring since it worked fine right before the move. Any ideas or suggestions on what else to try? I already disconnected everything and tried booting raw but no matter what I do it doesn't see the card. Tried removing tha battery also so out of ideas at this point .
