Well...
I have a computer that i use for dj'ing in my pub. I turned it on today to update the songs on it etc and it wouldnt boot 

. sometimes it gets to the screen that tells you the specs etc and but most of the time it goes to "Copywrite 

 1999 - 2000 Intel Corparation. All Rights Reserved." then the cursor just blinks below it.
It was working fine the other day. 
 
Its a dell L500cx.
900Mhz celeron. 
256MB ram.
80GB hdd.
Running XP Pro build 2600 or something.
Any help would be appreciated as i need it to work on Firiday.
