Trouble starting up-BIOS problem?

[Guest]

I have Windows XP Professional, and two days ago my mom deleted a folder in
the C drive for a printer (BIG mistake, I know!).
Now when the computer starts up it gets to the desktop, but then a blue
screen comes up and the computer restarts itself again, then goes back to the
blue screen. I used safe mode to see what might be wrong, and in Device
Manager I noticed that there's a problem with the Microsoft System Management
BIOS Driver, code 39: Windows cannot load the device driver for this
hardware. The driver may be corrupted or missing.

Does anyone have any idea what is wrong?

Did you try to do a system restore to a date/time before Mom did her thing?

I went to system restore, but when I tried to click on one of the dates it
wouldn't work.

The other option now is to boot from the XP CD and try doing a repair
install.
