Desktop pc video card wont function, neither does a new card function, any suggestions?

My video card does not seem to send a signal to my monitor. Everything except for video card work o.k. I went ahead and install a new nvdia card and still no signal. Everything seems to work fine except for the trasmision of the video signal between desktop and monitor, can anyone help?



Current windows: Vista

Brand: Emachines



tested and working: usb, monitor, ethernet, etc.|||Well aren't e-Machines supposed to be infamous for bad motherboards?

Anyway check everything is really tight and keep restarting it, i had that problem once and that was the resolution.



Sorry i cant help any more!
