Computer won't boot, "Stop: c0000135" Blue Screen

I recently tried to install Windows SP2, but the installation failed and after restarting the computer I received a "Stop: c0000135 {Unable To Locate Component}" error message and blue screen. The text underneath says, "This application has failed to start because winsrv was not found. Re-installing the application may fix this problem". The only CD I have is the Dell Re-installation CD that came with the computer. How can I fix this problem without losing any data/settings?

Thank you

Can you get into safe mode? Right after BIOS POST, press F8 repeatedly until you get the boot options. Choose Safe Mode with Command Prompt. When the command prompt opens up, type:


This will start the system restore utility. Follow the prompts to restore to the point just before SP2 install.
