window file protection error

[Guest]

When I start up I am getting following error:

Windows File Protectio
Files that are required for Windows to run properly have been replace
by unrecognised versions. To maintain system stability, Windows mus
restore the original versions of these files
Insert your Windows XP Home Edition CD ROM no
'Retry' 'More information' 'Cancel

I read an earlier post about uninstalling realplayer and as I recently installed radio@netscape with realaudio and realplayer, I uninstalled all of those. but am still getting error message.

Also, I now can't play CD or Games in CD/Rom without skipping

I'm definitely a beginner and have really messed something up I'm afraid

Any suggestions
