Thanks, the video card is NVIDIA GeForce FX 5200 But What I just did was that I installed new PSU. It's ATX 12v v2.0 and it gives 400W. So that should be enough right? But still it doesnt work and what I noticed was that when I had the AGP card installed and the monitor cable plugged to the VGA of the mobo (instead to the card) it worked as before. This seems strange because from my other experiences the mobo's VGA should not work if the is an AGP card installed, correct?
