Graphics Card Problem - NVIDIA GeForce 8800GTS

Hello…
This is my first time on the forum, thanks in advance for your help.
I have a GeForce 8800 GTS graphics card in a machine that I built and I can’t get the graphic card to work properly. I’ve installed and enabled the drivers – when I reboot the machine, I get the Windows 7 startup screen and then it goes blank. I reboot in Safe Mode – disable drivers – reboot, and it works fine with the integrated onboard drivers. My 6yr old HP monitor is connected to the graphics card using a DVI to VGA adapter (would this cause a problem? I was told no). The motherboard doesn’t have a dedicated video output, so the video I’m getting from integrated drivers is passing through this card. Everything in the machine is working fine except for this problem. I’m not a gamer, but I would eventually like to do video work on this machine and would like to get this card to work properly. In a couple of weeks I will have the opportunity to put this card in another machine but until then is there anything I can do to diagnose the problem?

OS – Windows 7 Ultimate Service Pack 1

System Memory - 3328 MB (DDR2-800 DDR2 SDRAM)
Video Adapter & 3D Accelerator – nVIDIA GeForce 8800GTS – Windows 7 compatible
Corsair TX650W power supply

"Integrated drivers" - I suppose that you mean the generic Windows VGA drivers.

Has your hardware ever worked in Windows 7?

Windows 7 is pretty good at including drivers, but it may not include drivers for your nVidia nForce 570 SLI chipset. (I had that with my nVidia/AMD laptop.)

They're available at www.nvidia.com. Make sure that you get the correct bit depth (32 bit, from what you've posted), and the AMD version (not Intel).

NVIDIA DRIVERS 15.58 WHQL

Windows 7 is pretty good at including drivers, but it may not include drivers for your nVidia nForce 570 SLI chipset. (I had that with my nVidia/AMD laptop.) The NVIDIA Smart Scan tool says I have the latest motherboard driver.

If the graphics card was shot would it still pass through video from the generic drivers??

No.

There is no video to "pass through".

Have you tried hooking something (tv) to the other video out on the card? You may need a vga cable for the initial setup.

Hooked up LCD TV with VGA input - same results. I believe TV was getting some type of signal because resolution parameters appeared on screen (1024 X 768).

A couple of questions, has this card worked correctly previously? If so, did it stop working after you updated the BIOS or after you updated the GPU driver?

Here's the thing, the card is working. Since you are seeing the post screen and Win7 splash screen, you probably have a bad driver. Try booting into safe mode with networking and uninstall the GPU(go into device manager and right click the GPU and select uninstall). Then go to Drivers - Download NVIDIA Drivers and click on "update drivers" this will automatically find the appropriate drivers for your system.

It worked with Vista, hasn't worked w/ Win7. I rebuilt computer with new 1TB HDD and new 4 GB memory, upgraded from Vista to Win 7. BIOS and GPU have been updated.

I'll give this a shot.

Didn't work. When the machine rebooted after I uninstalled drivers it would reinstall the original drivers before I had a chance to install the latest version. I scanned the computer to see where these were being launched from but I couldn't find it.

You could try Driver Sweeper:

Guru3D - Driver Sweeper

in Safe mode. That won't just uninstall the drivers - it'll delete them.

When you restart, the generic Microsoft VGA drivers should install.

(Note: I think that this tool is OK for nVidia drivers, but I'm leery of using it with AMD/ATI. I worry that it gets rid of some files that it should not.)
