My computer wasnt running right so i stupidly thought uninstalling my latest service pack (windows xp 3) and vista inspirat 2 would fix it......when I did that my display screwed up....i went to display settings and the only option was for 2 bit!!!! I have reinstalled boththings n it is still like this what do i do???

 
Try reinstalling your display drivers. They should be available through Windows Update and through Device Manager.

I did that i even went in through display setting..... advanced......drivers.....update driver......aggghhhh I think it happened b/c i unistalled Vista inspirat 2

 
Boot into safemode (press F8 during boot and select safemode), then uninstall your display drivers, boot into normal mode, and download the display drivers from your vendors site (e.g. Asus, Dell, HP, etc.) and install them.
 
If you computer is running weird, it might have a virus infection. Make sure you've a decent anti-virus and a good firewall installed. Make sure to run a full system scan for malware. If that doesn't help (or if you do find malware), completely reinstalling Windows could be a smart choice..
