Motherboard vs. video card

Specs: Win XP, 1 gb

I have a Compaq Presario S6500NX computer with 1 GB of ram, 3000+ processor. Since I placed a new ATI 9600XT video card, I have had trouble starting my computer. When the new AGP card is plugged in and the computer is turned on, the computer will start with the fan turning on but the computer will not continue its startup. The windows screen does not load and nothing shows up the on the monitor. Sometimes it will start and continue past this point on the first press of the power button but may not start until the 150th (literally) time i press the power button. When the video card is removed the computer it starts up fine. I have looked on other forums for answers, and i have found others on ATI's website, ASUS' website and Compaq's webiste with the same problem, but i have not found any answers. I have an ASUS a7vbx-la motherboard. The problem seems to be with the integrated grahpics on the motherboard. I have looked for a jumper/dip switch on the motherboard to turn off the integrated graphics but cannot find any. Does anyone know how to keep the computer from trying to find the integrated graphics on the computer when an AGP video card is placed into the computer or any other suggestions to fix this problem??? Thanks!!!

The setting for onboard graphics is in the BIOS. Disable it there.

If its not in the bios its a jumper on the motherboard you need to move to disable onboard VGA

I have tried to turn it off in the BIOS and i doesn't work. There are no jumper/dip switches on the motherboard that control the integrated video. Any other suggestions? I have read that others have had the same problem with not being able to turn it off in the BIOS and not being able to find jumpers.

Unfortunately With your Presario S6500NX, there is no manual overide either in the BIOS or on the motherboard, and this is not uncommon OEM's.

Installing an AGP card automatically disables the onboard video. You just make sure you've removed the prior drivers and check device manager, then install the 9600XT AGP card.

Another possibility is the minimal power supply unit not being able to run that much equipment. Just another reason not to get a Compaq in either case.

Ok take the card out. Boot into windows and disable onboard video adapter through device manger. Shut down the pc. Put the add in card back in and reboot.

Note in the bios you may find an option to tell the PC you are using a addin card rather than the onboard graphics.

It is the powersupply. I have the same system only went to a Nvidia 6800ultra and had the same problem until I upgraded to a bigger powersupply. The case requires one small piece of metal cut out of it, less than half a square inch, and the power supply fits perfectly in the compaq case. The 250watt compaq gives you is no where near powerful enough, just read the system requirements on your cards box.

I purchased a 400 watt power supply to replace the 250 watt power supply that came with the computer. No luck.

Same problem. Although when i remove the video card, the computer works flawlessly. So it is the video card. I don't know if it's because the computer won't turn off the onboard graphics or what, any other suggestions??
