i have a serious pblm with my card . i am using XFX GeForce 8800 GT Alpha Dog Edition 512MB.
Processor : i3 530 (2.93)
Mother board : Intel DH55TC.
RAM : Corsair 2gb DDR3
Harddisk : 1.5 TB
i have a serious issue with my nvidia graphics card. when ever i boot my system, i am getting normal beep sound but my monitor is not getting input. When i reboot the system for 3 or 4 times, then it start working fine, ie i can see something in my screen.
It happens everytime whenever i boot my system with graphics card.
I tried removing my graphics card and it is working fine with my onboard graphics.
Have you tried to set the BIOS , under the VGA/Display option to PCIE?
If not change it from whatever it is to PCIE.
Save reboot a few times and give us an update.
Also check it you have the power to the card plugged in correctly plus the card not heating up at startup.
You'll need to go to the advanced tab and then to the Primary VGA adapter, change from Auto to PCIE
