sp2 boot problems - hard disk error?

[Guest]

Any help would be appreciated.

I am running Windows XP Pro on a Compaq Presario notebook. I just installed
SP2 and the computer does many things:

1) begins boot very very slowly
2) does not load anything but my desktop background
3) says that my hard drive is going to crash and that I should back
everything up, but I can't because I can't boot completely
4) at times pops the "blue screen of death"

I have tried Safe Mode, Safe Mode with Command Prompt, and Last Known
Working Settings (or similiar title) startups.

Is there any way to uninstall SP2 through Safe Mode?

Or can this be fixed? I really need this computer for school.
