Need help with my 9800GT graphics card

After you install the card and try to run it are you connecting the monitor to the card or the onboard video? The only thing I can think of is to disable the onboard video and connect only with the new card.

I have tried disabling the on board video, uninstalling all the old drivers, then installing the video card and connecting the card to the monitor. I always just end up with a black screen on my monitor. Computer will run normally, graphics card is powered. No signal is picked up on my monitor, though. I wonder why the card does not appear on my device manager at all. Shouldn't it be under the display adapters as a vga controller or something of that nature? I'm starting to think that it is a faulty card.

I'm having the exact same problem with the exact same card.

Card not found in Device Manager

One problem is that the latest set of Nvidia drivers does not contain the 9800GT in the inf file, but I fixed that and mine still isn't working.

Which driver version are you using? The 196.21 is the one that does not look for the 9800 GT...gotta either use a modified NVAM.inf file or use the 186 driver set.

Yeah, I've been looking at your thread as well, hoping your fix could be mine as well. This is just frustrating the hell out of me. I know nothing about modifying any type of code. I don't want to risk messing things up further.

This is easy - if the card doesn't work, replace it. If that doesn't work, your PCI x16 slot is dead. If it does the card is dead. One last option - if you have a Plug N Play option in your BIOS disable it. Is your slot v1.1 or 2.0?

My PCIe is 2.0. The only plug and play on my bios is for usb and it's currently set to enabled. Is that what you're suggesting that I disable? I'll try that and see if it works. The only thing is that I use a usb mouse, so that might not let me get into my computer.

I'm probably going to file an RMA with PNY. Couldn't hurt, right?

Could be IRQ related, try this, download and save your driver to your computer. Disable your onboard graphics from device manager. Power off your computer. Remove the 9800GT from your PC. Remove your memory chips. Remove the power cables from your cd drive. Put your 9800 GT back in. Put your memory back in. Leave your CD player unhooked. Hook your monitor to your 9800 GT, and power on your pc. Your pc should now recognize your 9800GT. Install the drivers for the 9800GT and unintall the onboard graphics. Restart, make sure everythings recognized then power off and rehook your cd player.

USB is most likely for navigating the BIOS - I would try a different card. As for IRQ's disable the serial and COM ports in your BIOS to free up resources assuming you don't use them.

taking off all peripheral hardware, speakers, cd/dvd, and using minimum ram should free up enough adress space to get the card recognized
