Windows 7: GeForce 6200 TurboCache not working properly

Hello; I've done some searching and experimenting, and at the moment I'm at a loss.

I've recently (a few hours ago) installed Windows 7 on my computer, at the same time as installing a new master HD. Most of the system came back up fine, with the exception of my second monitor/nVidia GeForce 6200 TurboCache card. In Device Manager, it displays with a yellow exclamation point; I've tried updating the driver through Device Manager both by using the default "update driver" option and allowing Windows to select it, and by manually installing three separate drivers (190.38, 191.07, and 96.85, which was suggested in another thread here). None of these have worked. Similarly, when attempting to run Windows Update, the optional update "nVidia - Display - NVIDIA GeForce6200 TurboCache(TM)" shows up as available, but fails to install each time I attempt it.



Given that I did have the case open for some time while installing the new HD and clearing out the dust, I'm entertaining both hardware and software/driver suggestions. I've run out of ideas for today and would be very glad to hear anyone else's suggestions. Thank you very much.

Hi. You left out the most important part, even more important that video card itself, when dealing with problems like this.

Please tell us which motherboard you're using.

Also, is that an AGP, PCI or PCI-e card? If it's AGP, your chipset may not be supported. If it's an nForce3 or lower motherboard using AGP card, forget it. Will not work.

Does that yellow exclamation point have an error code 43, perhaps?

Motherboard information:
Board: Gigabyte Technology Co., Ltd. C51-MCP51
Bus Clock: 200 megahertz
BIOS: Award Software International, Inc. F2 10/06/2005

Card is PCI-e, and of course it is compatible. Perhaps I was unclear on this in my first message, but that card has been installed and working for quite a while (four years or so)--the ONLY changes to the system were the hard drive and the OS; no other hardware was altered, and all hardware was functioning properly less than an hour before these problems manifested.

You say "only" OS, as if that's a minor change or something.

Best bet here is to look into updating the chipset drivers for the motherboard before installing the video driver. Bios update, if available, is always good as well. You won't have to use the device manager install method. Just run the video driver .exe and let it complete.

Which error code is the video driver giving in the device manager, currently?

Which one of these,

GIGABYTE - Product - Motherboard - Products

might that be?

I'm aware it's not a minor change, but your prior response implied an understanding that I'd changed other hardware at the same time; I'm trying to specify exactly what was and was not changed, and what was changed was only the HD and OS. It's an exclusion, not a qualifier of import.

I neglected to add the error message in the last post, it's:
I have two display adapters, both very similar; I've run the video driver .exe as well as using the device manager, as I'm not sure whether the video driver is installing for the card or for the on-board device. As of this morning, I've also swapped the monitor plugs at the back, simply to eliminate the potential of a problem in the cables and/or monitors themselves having developed; everything is running as it was last night, but on the opposite screen.

I will look at updating the chipset drivers, and will certainly welcome further feedback as I proceed. Thanks.

The two ways to fix that are to update the bios and then disable all unused ports like serial, parallel, floppy...everything that is not used.

Good luck and let us know if this helped for you.

Also, disable the onboard vga video in the bios and attach the monitor(s) only to the 6200 card.

As far as I know, the 6200 card only supports one monitor, and the configuration of having both enabled has worked perfectly for years. I don't know if installing 7 has affected that, but I would prefer to reassemble everything as it previously was, rather than having to drop a monitor.

Nah...if it has two ports for video on the back of the card, it will support both monitors easily. That's how you want to run if at all possible.

If the 6200 starts working and I can find an appropriate cable to connect the second monitor to it, I will try that. Currently, I'm researching updating the BIOS and will go from there. Thanks.
