Windows Xp and Just a blinking cursor

I start my Dell latitude 620 this morning and all I get is
A) windows splash
B) black background
C) left pointing Mouse

What I have tried to do
* inserted my Windows XP disk and
* then set up windows Xp, Now push enter
* F8 to agree
* then R to repair

When all is done and restarts I still just get the Windows splash screen and the left pointing mouse

Any suggestion would be MUCH appreciated

Thx
