All three of my small PCI E slots do not work.... I thought it was my sound card originally, but I RMA'd my card and they sent me a new one. I tested the new one in every single slot and it still won't be detected. My video card works perfectly fine, and my computer boots up with no issues at all.... Should I just RMA the board? It is a Sabertooth z77. I got it about a year and a half ago.
