I have an old Asus A8N SLI motherboard and was running an 8800GT graphics card. Yesterday, I tried booting my computer and it wouldn't boot. I swapped out my 8800GT for my 7800GT and it boot just fine. So I considered my 8800GT has bit the dust. I went and bought a GTS 250 and am experiencing a similar but different problem. The computer boots into Windows (I can hear the chime) but I get no display. Its not a Windows problem because I get no display period, just a black screen. I've tried flashing the BIOS, tweaking BIOS settings, resetting CMOS, etc and nothing seems to work. The only thing that my computer will boot with is my 7800GT. Any ideas?
