Hi. I just bought a nVIDIA GeForce 6800 GT so I could upgrade my system and keep up for a bit longer with the newer games.
I have upgraded video cards a few times over the past few years and never had any problems until now. After installing the new card and making sure everything was connected ok I downloaded the new drivers from Nvidea but after installing them and restarting the system I get a "found new hardware" box come up and hardware wizard launches ...says its installing my new hardware but then I get an error saying it failed beause the data is invalid????

I have repeatedly tried redownloading and installing the drivers from nVidea but keep getting the same error. Can anyone help?? I have been busting to get this working as I have had a brand new copy of Crysis waiting to play but need the video card upgrade to make it work.:cry

 

I noticed you have an SiS chipset. SiS has a seperate driver for the AGP slot, and when it's not installed properly (or outdated in comparison to the AGP card in the slot), it can cause strange things to happen. These things can also happen with the AGP driver in SiS chipsets for no reason whatsoever. Anyhow, shut down the PC, remove the power cord, and remove your 6800GT video card. Plug into the on board video or use your old video card. Boot up and remove the NVidia software. Run a temp file cleaner while your at it to be sure. Here's a link that may help with removal: http://nvidia.custhelp.com/cgi-bin/...GV4dD11bmluc3RhbGwgZHJpdmVy&p_li=&p_topview=1
After the NVidia drivers have been removed, reboot the PC and locate the newest available drivers for your chipset. I found these at GigaByte's web site: http://www.giga-byte.com.tw/Support/Motherboard/Driver_Model.aspx?ProductID=1699
You'll notice that the chipset driver is actually an AGP driver. Download it. DO NOT install it yet. Go to Add/Remove programs and remove the SiS AGP driver if it's listed. When it's done, or if it isn't listed, shut down the PC and unplug the power cord and put the 6800GT in the AGP slot, be sure everything is hooked up correctly, and power up. Now, install the new SiS AGP software, If it asks for a reboot, reboot. If not, install the newest NVidia driver for the 6800GT. Reboot. All should be OK. If it's still giving you weirdness, it could be because something is not uninstalling completely from the registry, or from the system files and a 3rd party software/driver uninstaller may be needed.
Good luck!

 

Ok...well that sounded really easy until I got to the part where I'm meant to uninstall the nVidea drivers...when I am in "add/ remove programs " nVidea Drivers is on the list but when I click on "change/remove" nothing happens. Not a thing. Any ideas??

 

Oh....and now sisnce I tried to uninstall the nVidea drivers and took out the 6800GT I no longer have a internet connection. Beats me why this would be as I never changed anything there!!

 

Ok. I finally got my internet connection back. Must have bumped the lan card as it was loose. I still cant seem to uninstall the nvidea drivers.

 

Ok..thanks for your help but its sorted. I did a clean install of windows after a few other things started stuffing up and its all good!
