Boot up probs, not horizontal lines

[bklyn1028]

Foxconn WinFast mobo....amd athlon 64 3500+...Nvidia 6800GT card...2GB ram...Computer comes on, but monitor stays black. AFter hitting reset button about 20x, it posts....and works fine...This was days ago. NOW, same thing, but have horizontal lines on monitor. I'm thinkin the video card is shot, any other thoughts?

Make sure that the capacitors on the motherboard aren't swollen or leaking.
