Drivers Problem

My cousin's computer conked. Kept auto restarting, then prompting to start up in which mode (safe mode, last known good configuration, start normally).

He just got back from breakfast. His father drove.
As soon as he entered the house & saw me...
The Cousin: Hey, something's wrong with the computer. Can check??
Me: Ya, I know. Saw it already.

(I had tried to on it that very morning. When I startup in safe mode, it ran all the way til Drivers/agp440.sys , then it stopped & auto reboot after awhile.)
Me: It's drivers problem
The Cousin: Drivers problem?? How to fix it?? Can you fix it??
Me: (being sacarstic) Ya, I can fix it without any tools
The Cousin & Me went on blablabla...

His Father: Hey, don't simply blame it on the driver ok?? It's not the driver's fault..
(If you don't get it, His Father was referring to driver as in the one who drive the car)

Later that night...
The Cousin: It's the drivers problem then how to fix it?
His Father: Hey, stop blaming the driver k?
The Cousin: Face it, it's not the passengers fault...

FYI, His Father do understand we're referring to the computer & was making a joke...

Ok, jokes aside... If you face that problem..
Of course you can actually Google it & find your answers.
But I'll make it super short & sweet..
Just get your XP cd (considering you're using XP) & insert to the computer.
Run repair: R
Then when the command comes up, key in chksdk /r

That should work. What if that don't work? Google it or get an expert la then...
Not my problem also.. Hahhahaha *evil*
