Dell ispiron 530 video question

[Linda]

I have a Dell ispiron 530 desktop that came with 8.04 LTS. I 
have upgraded it to 10.04 LTS and the person using it says 
it keeps giving her a graphics error requiring her to 
reboot. I told her to write down the error message for me 
the next time. Anyway I started looking through the 
paperwork that came with it but could not find out anything 
about its graphics card. Has anyone had to do anything 
special with their ispirion 530 since they upgraded to 
10.04? Any thoughts on what I should be looking for?
                    Thanks
                     Linda
