Everything else works fine!
What does that mean? Do you hear a single short beep (if you have a case speaker installed) as your system completes the POST?
No beep, everything is not working fine.
Do you get a "TaaDaa" sound when Windows finishes booting (assuming you had it before)?
If no "TaaDaa", everything is not working fine. If "TaaDaa", test the video card in another system.
