Hello, I have tried to get my monitor to detect my PC. I have used many different monitors and VGA cables. I think their may be something wrong with the onboard graphics card. It seems to be KIND of loose from the motherboard. I went and bought a Nvidia Galaxy GeForce 8400GS 512MB card. I plugged it in and it would still not WORK. I plugged the VGA cables into the old onboard graphics card and for some reason it worked. I installed the drivers and restarted the computer. It told me I could not use the new graphics card because it did not have enough resources. I disabled the old onboard graphics card from the DEVICE manager. I turned off the computer and put the VGA cable into the new Graphics card. After that it did show the display  and started to work. I restarted the computer to see if it would still work to just make sure and it would not display on the monitor again. I plugged the VGA cables back into the Old onboard graphics to see if i could get it to work again and it would not. Is there anything I can do?

My computer is an HP Pavilion a6000
It has windows vista. It has 7gb of ram
It has a AMD phenom x4 processor Have you checked that the BIOS of the motherboard is everything ?Did you disable the onboard graphics from your BIOS?
