Sure, all you have to do is press start and go to help and support and type in system restore. One of the answers is to run the system restore wizard which allows you to bring up earlier times that XP has backed up your system. Hopefully, you still have a point that you can go back to before you removed you sound card driver information. In addition, if you go to the control panel and under system then the system restore tab you can choose to allocate how much hard drive space that you want for backing up your system. Finally, you can use the help and support to create a save point for your system if you are going to do something potentially dangerous in the future and want to have a safe point before doing the action. Feel free to reply if you still have problems.
