vga64k infinite loop error?

Hey guys i just bought a cheap dell optiplex gx150 from pratt and whitney (refurbished) just as a backup comp, i went to install xp on it and once it was done copying files it did the restart and it just keeps going to the blue screen of death with a vga64k infinite loop error
for the life of me i cant figure out how to fix it! Has anyone else had this happen to them before and could you give me some advice?
Heres 2 shots of the screen


Thanks for the help
