Dell :: ATITools Forced ... Underclocking

I've been trying to overclock my Geforce 7900 GS Go for about two days now. I've been using these boards as a resource, but now I've hit a very strange wall and I hope someone can help.

I flashed the bios using Julanu's Method and I made sure to determine what revision I had. Everything there worked fine, but when I tried to use ATITools to find my max frequencies, the program eventually forced them down and KEPT THEM THERE.

"I Clocks level 2 set to: 0.03 / 100.00" and it never switched to try another frequency after 12 hours of running. To make matters worse, I couldn't change them back to normal after aborting the test! nTune reported the same results; the slider bar was unmovable. Essentially my attempt to overclock seriously undercocked my card!

So I uninstalled the drivers, reflashed, reinstalled and tried rivatuner. Everytime I attempted a change, the settings jumped back to stock. Then when I restarted my laptop it uninstalled the graphics drivers! Now as I try to reinstall the Dell drivers (the old ones that allow for nTune), it won't install because the it claims that the setup can't continue because it "can't locate drivers that are compatable with my current hardware." Pretty sweet since its a driver made for this by dell and nvidia...

Even when everything was working, I was never able to use nTune because I don't have at least an nForce2 Mobo.
