when I start up my computer, it boots fine, it gets to the windows loading screen, then my screen turns black and says: off mode in 5 seconds, I wait a while when it in off mode and it comes back on an displays a blue screen that says this:

the problem seems to be caused by the following file: ati2dvag

the device driver got stuck in an infinite loop. this usually indicates problem with the device itself or with the device driver programming the hardware incorrectly

I have the latest drivers
it's an ati radeon 9550
what do I do :S
