Problem Upgrading Ati Radeon 9800 Pro to Nvidia Geforce 6600GT

Hello,

I've been running an Ati Radeon for about 8 months now in my PC. The fan has recently deteriorated and it regularly overheats so I bought a PNY Verto GeForce 6600 GT.

Old gfx card: Sapphire Atlantis Radeon 9800 PRO 128 MB DDR 8x AGP
New gfx card: PNY Verto GeForce 6 6600GT AGP8x 128MB GDDR3

These are the steps I followed:

1. Took out old card and put in the new one.
2. Booted up the computer.. and whilst using a very scrambled screen managed to uninstall all the Ati drivers and programs.
3. Rebooted, installed the Nvidia drivers that came with the card.
4. Screen was still scrambled so put Ati back in and used Driver Cleaner to remove all traces of Ati drivers and software.
5. Put Nvidia back in, installed drivers again and same scrambled screen problem.
6. Current situation - put the Radeon back in and it still seems to be working fine without any Ati drivers. Display is not scrambled but is "sluggish" when I scroll up and down on webpages etc and not smooth.

Screenshot of what I mean by scrambled screen - http://img382.imageshack.us/my.php?image=screeny3eh.jpg

My PC specs are...
Shuttle SN95G5 Socket 939 Barebone NVIDIA nForce 3 Ultra chipset Black
AMD (Winchester) Athlon 64bit 3200+
Corsair TWINX1024-3200C2 DDR-DIMM 1024MB
Seagate Barracuda 7200 200GB Ultra ATA/100 7200rpm 8mb Cache
Windows XP Professional

Where do I go from here? Should I re-install Ati drivers and then uninstall again and then change the card? And the last thing I want to hear is format and re-install windows!

Many thanks in advance,

Taricco

Hmm, my ATi to nVidia switch was much smoother. Windows XP has basic drivers for both video cards, but they are sluggish as you mentioned.

Try uninstalling the ATi drivers (just the reference ones, not the Windows ones) and remove the card. Install the 6600 and install the latest set of drivers from nVidia's site.

Thanks for the reply. I started again - removed all drivers for everything, ati and nvidia. From the add/remove programs AND using Driver Cleaner. (I did all this in safemode btw because with the nvidia drivers installed, the monitor kept switching off if i booted windows normally).

When I put the Ati in, the windows VGA drivers kick in and the display is fine - just sluggish which is how I think it's supposed to be. When I put the GeForce in, my screen is messed up right from the off - the bios is all scrambled, there's funny coloured lines going down my screen as windows is loading etc.

Incidentally, when I turned my PC on this morning, the 6600GT was running fine - the screen was normal when windows was booting - it was ok for about 15 seconds into windows and then it all went scrambled again. (This was with the latest nvidia drivers from the website). The monitor also kept going into sleep mode by itself and "drifting in and out of conciousness" if you will.

SO i've decided the card is faulty and will go back to the vendor! Thanks for the help.
