Do you have integrated graphics on the motherboard taht you can try to plug into and see if you can get a signal that way? Can try clearing CMOS as well.
Clearing CMOS means unplugging the computer from the wall, press the power button a few times to drain extra power, and then remove the small silver coin battery on your motherboard. You may have to short a jumper as well...refer to your motherboard manual for this. Take the battery out for about 5-10 minutes and then put it back in.
yes, i think.....the m/b has a monitor connection. tried to hook up to that after i removed the graphix card, but still nothing.......how do i clear the cmos?
Also, make sure your RAM, and all your cards are seated properly. I know that if you don't have RAM seated tightly, you won't get a display on the screen (found this out the hard way before lol).
