Windows booting problem

[THOMASGUSH]

I shut my computer down while a few programs where still running due to it freezing. I now try to start my computer and it goes right the screen with the options to either;

Start computer on Safe mode
Start computer Safe Mdode Command Prompt only
Start using last succesful configuration
Start Windows normally

No matter which I choose my computer goes to starting up Windows...Then fails and trys again...Right before the computer turns off to restart I see a blue screen for a very breif moment. It is an endless cycle....Is anyone familar with the problem? I can't get past this blue screen.

I am not that computer literate, but I think it might be a virus. If anyone can help me I would appreciate it.

Thanks

Try last good config again. No joy?

What percisely does the error message say?

Try, at the command prompt, typing

scanreg /restore

and choosing a time when your computer worked.

 I didn't note your Operating system? That information would be helpful. maybe I missed it?

It's very possible that you DID get a virus... However, I need to know.... Did you have virus protection?
