Windows 7 64bit doesn't recognize my Geforce 9800GT

[fredypcm]

Hello guys!
Here is my situation: I used to run XP 32bit on my computer for over 1 year and never had a problem with my graphic card. But yesterday I decided to install Windows 7 64bit, as it permits me to run more than only 3GB of RAM (I have 6GB). And there is where the problem is, as ever since I installed the new OS, my computer wont't read my nVidia Geforce 9800GT properly. It displays my graphic card as Standard VGA Adapter.

I already updated the driver of my motherboard to the latest one, and tried to update the driver of my graphic card from NVdia's website, with no success.
So is there anybody who had faced this problem before and came out with a solution? Or the only solution I got is to go back to XP?
I would be very grateful if somebody could help me out on fixing this problem.
Thanks in advance!

Fredy

Additional notes:
I also tried to install Vista 64bits on my computer, facing the same problem.

The change to 64 bit shouldn't really be affecting this. Especially on a card that is actually supported by windows 7 out of the box. It should have actually auto installed drivers from windows update.


...speaking of which have you let windows update at all?

Finally for future reference you can attach images here directly, just use the paperclip icon in the posting box.

Yes, I downloaded and installed every single update from windows update list, except for some of the optional and language pack ones. There is something really intriguing about the 1st SS I took, which was taken from the AIDA64 application. It shows my Video Adapter as Standard VGA Graphics Adapter (14MB) and my 3D Accelerator as NVidia Geforce 9800GT. Is that supposed to mean something? When I try to install NVidia driver, it says it couldn't find any compatible hardware in my computer.. any thoughts?

1 - download this specific driver to your desktop where it's easy to get at. Graphics Driver - GeForce 285.62 Driver - GeForce

2 - scrub the nvidia - display driver off your system with driver sweeper in http://www.sevenforums.com/tutorials/69585-safe-mode.html

3 - Reboot normally then run the driver install you got in step 1

Hopefully detection will occur now.

I opened Driver Sweeper, selected NVidia Display, clicked at analyze and then clean, all of this in Safe Mode. No luck with that, it's still the same. NVidia installer shows it couldn't find a compatible hardware.
