Need help with my 9800GT graphics card

I was given this card as a Christmas gift and I recently installed it (or tried to, at least)as well as a new PSU on my Windows 7 PC. The card is a 9800GT 1GB GDDR3 PCI-e graphics card. The problem is that it was never detected as new hardware, nor does it show up in the device manager.

I have an onboard video card that is a 6150 LE. I can see video when I hook it up to the onboard video card, but when I connect my monitor to the graphics card, there is only a black screen.

I was wondering if anyone could provide some helpful tips for this. I'm getting desperate; I tried getting the card to work all day today with no luck. I know there are some other threads with this same video card, but the majority of them do have the video card in the device manager. This situation may be more unique. I'll provide my comp specs if needed.

Thanks in advance for your help.

Windows should detect the new gfx card on a reboot typically.

You may have to go into the bios of your computer and disable the on-board video before it will detect. I would try that first. Look for anything in the bios related to your on-board video.

Also in device manger try disabling and uninstalling the on-board gfx adapter and rebooting the machine with the new 9800gt. I think though, with a little looking around in the bios, you will find once you disable on-board gfx, windows will detect.

Good Luck

So I disabled and uninstalled the on board video and tried to start up using the graphics card. The problem is that my monitor shows no signal when I start up the comp. The computer automatically installed the drivers for the on board video card.

Everything seems to be running fine. The card has power going to it. There's no beeps or anything that might cause alarm. I tried removing and reinstalling the graphics card, but that does not let windows pick it up. Is there anything else that might cause this problem?

Give us the make and model of your computer or your motherboard if you know it so that we can tell you how to enter the BIOS and turn off the onboard video.
Deleting/disabling the onboard video in Windows won't do anything to solve the problem with the 9800GT.

My motherboard is an Asus A8M2N-LA. I have updated the bios as well as the southbridge chipset. Would the graphics card appear in the bios if it isn't detected in windows?

Okay so here's a little update:

I removed the card and checked all the connections. Everything seems to be in working order. Card is connected correctly. I have three different cables: a VGA, DVI and a HDMI. My monitor has connections for all t hree. I tried using a different monitor and I get the same thing: it will boot up through the on board, but no the card.

I just flashed the Bios on my motherboard by removing the battery for a couple of minutes, hoping that would help my situation. Now my computer is frozen on the blue HP startup screen. Did I do something wrong? Is there any way to fix this?

Removing the battery just resets the bios to original preadjusted setting. Your bios will need some further adjustments to work correctly. Removing the battery is like clearing the cmos but also resets the bios clock.

Flashing the bios means to update the bios, usually to a newer version of the bios.

You will need to go into bios and enable your SATA drives and also it's very important to reset the bios time/date to current time/date.. There may be other required adjustments like setting the memory to manufacture specs but it's very difficult to see those settings from here so I can only guess.

I'm not sure why your GPU isn't being picked up by Windows but usually just cleaning the contacts on the card and reinstall making sure it's seated correctly in the Top pci-e slot will fix those types of problems.
