Hi guys I recently tried to upgrade my PC with a New GPU, PSU, and an SAD. Now when I start my computer it shows the GO screen with press each to access start menu. After that it goes to a black screen with my computer specs and the Same press each for start menu message. If I press each it says start menu In the bottom right corner of the black screen without actually opening the start menu, and I can't access any other menus (such.as boot or bios) either. Can Anyone tell me how to fox this problem? Thanks.
