Another 9800 GT card!

I have Windows 7, Build 7100, and my 9800 GT isn't showing up in the device list. It powers on perfectly, then fans run, and it works in a computer that runs Vista... so my guess is, after seeing all the problems people have been having with the 9800 GT and Win7, it must be the combination of the two. I just haven't been able to figure out why my computer refuses to recognize the card.

Build:
AMD Athlon 7850 Dual Core
2 Gigs Ram
Asus M4A78-E Motherboard
32-Bit Operating System

I have the same build with an EVGA 9800 GT and it's recognized and working fine. However, after upgrading the motherboard, memory and processor HDCP is no longer working. Not sure it's the video card but I've not spent a great deal working on it. HDCP was working fine prior to the hardware upgrade.

Sigh...

In any event your issue may very boil down to several things such as BIOS configuration (make sure the BIOS is set to use PCI alternate video first), power supply (make sure the 12V leg has enough amperage) or something else goofy with the motherboard.

I can't install latest Nvida drivers for 9800GT. I'm currently running the standard VGA? drivers. Still can't find a solution for this.

I'm on Win 7 64 bit OS, migrated from Win Xp 32 bit OS.

I have noticed something in common among people having trouble with 8800 and 9800 cards, Most of them seem to have "ASUS" motherboards. Don't know that this is your issue but I have run 8600's, 8800's and 9800's all in SLI and there have been no issues what so ever with my XFX nforce motherboard.

By the way....how is your bios....I had to get an updated beta bios for my motherboard for Win7 x64 compatibility (It was fine with Vista x64). Current Nvidia driver as of 10-08-09 was 191.07 which solved some issues for me as well as other people posting here on SevenForums.

Are you downloading the drivers from Nvidia or from Windows update? The ones from Windows update messed my system up and I had to back them out. Now I download them myself from Nvidia and haven't had any problems since.

yeah i've noticed that too with the ASUS motherboards. i also had the same problem with my card not working right with the windows driver update and having to back out. i've helped several people with mobile cards on asus motherboards, mine is a 9600M GT. it always came down to the subsystem ID not being defined properly in the INF files that nvidia provides. i'm not sure what the deal is with the 8800 and 9800 cards, but it may be something similar.

the key is looking for the PCI device ID in dxdiag.txt, which looks like this: "Enum\PCI\VEN_10DE&DEV_040C&SUBSYS_20D917AA&REV_A1"

See his board has the intel chipset GIGABYTE - Product - Motherboard - Specification - GA-P35-DS3L (rev. 2.0) In this thread one poster has an Asus and the other has the same Gigabyte board. 9800GT Black screen only with Win7/Vista x65 drivers

For people not experiencing this issue with Vista but only when they loaded Win 7 their is a way to import the drivers from Vista to seven that may fix this. Here is the thread on it Windows 7 driver solution Hope this can help.
