Need help with wierd graphics card problem

[sandy777]

I have a bizarre video card problem. I recently tried to upgrade the video card from an old (socket 939 system of mine). The old card is a Geforce 6200 PCI-Express card, and I was moving over to a Geforce 7600GS. My system works fine with the 6200, but as soon as I replace it with the 7600GS -- the following happens. The system posts and I can get into BIOS...but if I let it go to Windows, the screen blanks out right when Windows starts to load (I never see the Windows logo). I know Windows starts up correctly because I eventually hear the Windows startup music....but the display is totally blank. If I put the 6200 back in everything is fine. I tried the 7600GS on a different system so I know it's not the card. I even pulled a 7600GT from a different system and tried it with this one and I get the same Windows blank screen problem. I tried it with 2 different power supplies (one 400 Watt and one 500 Watt) -- same result. There is only one hard drive and 1 CD-ROM drive so I doubt if I'm taking the power supplies much.

My system:

Motherboard: ECS NFORCE4-A939 (Socket 939)
CPU: Athlon 64 3200+
Memory: 1GB PC2700 DDR
Power Supply: Fortron 400 Watt / Xclio 500 Watt (Goodpower)
Hard Drive: Seagate 60GB IDE


Anyone have any ideas? I really hate to be stuck with the 6200....

You must uninstall the NVidia Graphics drivers first, with the 6200 still installed.

Before you do that, download the the driver for the 7600 from the NVidia website, and place it in a directory where you can quickly find it (My Documents...?).

After the computer reboots (still with the 6200) run Driver Cleaner, or clean the registry, and remove the C:\NVidia\(Driver Number) directory ("Driver Number" is ex. 84.21).

Shut down the computer. Replace the 6200 Video Card with the 7600. Start the computer.

Install the new driver - make sure you have downloaded the one that supports your card!

Good luck!
