Whenever Windows Vista starts I keep getting a error on my screen. The error is related to some display driver failure. It shows Display Driver R300 failed to work and recovered. I am not able to work on it properly. The system freezes for a while and it went back to normal when I logout and login. I checked the gpu that I have. It is some ATI X700. The driver looks to be working perfectly. To ensure minimum loss, I had disabled the gpu and enable the onboard video card. It is working stable without causing any error.
