portrait of computer idiot

Im writing this at internet cafe because my computer is not working anymore and I waiting for the computer shop to open so I can have my computer formated and OSs reinstalled. Last night I just got fed up, went to control panel>uninstall programs and uninstalled ATI drivers and ATI control panel. Then I went to program files at drive C and deleted everyfile with ATI or Radeon on it. So ofcourse when I tried to install my drivers fresh of my disk, Ill I got were a bunch of error messages staring at me in 16 color.

nikumba- When I get my computer back, do I really have to uninstall ATI drivers and ATI control panel to install directX9 ?(I dont want to go through this again). And is the catylst driver from ATI just an update, or do I have to uninstall the driver that came on my disc to install the catalyst driver?

I have a couple of other questions since were on the subject. I read that XP runs games at 60fps because it doesnt recognize the framerate you set on the OS, and when I tried to run CFS3 on my XP patition, thats what happened. How do I fix that? Also Ive had a problem with this new graphics card and my last two graphics cards (geforce 4mx440, geforce 2mx440) where when I run the flight sim “Battle of Britain” when I exit the game in 1024×768, my monitor goes into 800×600 and 60fps. My new graphics card only goes into 60fps. What can I do to fix that?

thanks everyone for your help
