I previously had an NVIDIA 550TI installed, so before I physically installed the 280X I uninstalled the 550 TI's video drivers. I seated the new 280x and the computer will not boot up. I then put the 550TI back on and the PC boots up just fine (of course at a lower resolution). I reset my BIOS by re-seating the BIOS battery and it did not make a difference. I also went to update my BIOS, but it says that I have the current version. I currently have 600 WATT power supply (Thermaltake TR2-600W). From what I've read, a 600 WATT PSU should run the single card. The 280x's fans turn on when I power the PC, but my monitor remains black. I tried different cables, different monitors etc. and nothing seems to work. I'm lost. Any help would be appreciated.
