I get a post beep,all the lights come on,I have complete power to everything,only I dont get a image on the monitor.I have swapped out 2 different video cards(Radeon 9600 Se AGP,and a Radeon 7500 PCI) i still have no video.I also have tried different monitors,and different cards to different monitors.I still have no video.I installed xp home on my harddrive and it was working,then I shut down and when i turned it back on my video was gone.Ive tried reseating the motherboard,and playing with the cmos,but i havent had any luck.What shall I do?
