Please try and find your Graphics card and motherboard info. Type msconfig into the run box and hit the startup tab. Look for Nvidia or ati somewhere. You should be able to cross refrence the driver with the internet and find out which card it is.
EDIT: open your comp and see what the card is
Dude seriously WTF? Now you have him cracking the case just to find the GPU? Go to start, go to run, type dxdiag, copy and paste what is on the system tab and the display tab. WTH!?!?! crack the case... damn... msconfig will just get him startup programs and messing around with services.
Do I think you are lucky never having a driver problem? Which incidentally is a piece of software. No I don't, I am fairly positive given your troubleshooting technique so far, that you wouldn't even know that you are having a driver problem if you saw one.
