The Volume Is Dirty~

Here's what happened:

A power failure causes my PC in the office to, well, suddenly shut off. When the power goes back in, I boot it up, and after the Windows loading screen finishes, I get a ChkDsk, saying that the Volume is Dirty. So I leave it be to finish its cleaning, but the thing is, it's taking up a lot of time and I reeeeaaaalllly need to use the PC for my duties. It took up a couple of hours and I didn't finish it because I had to turn it off for the day.

The last thing it was doing was being asleep. The programs that were running before the power failure were Notepad, and a Remote Desktop connected to the company's server.

The specs, as far as I can remember, are:
~>512 RAM
~>Pentium 4 (M) @1.15GHz I think
~>It's a Dell Opti-something
~>Windows XP

How can I fix this problem? If you think I left some details, just tell me ^_^

Oh and BTW, I can't get the log file because I always left the PC running for it to finish it's cleaning. Maybe I can get it tomorrow, if they allow me. Haha.

Thankees in advance~
