Help me with my driver problems

[noobody]

Trying to get a better performance for my jpcsp I decided to update the graphic card driver. Then I went to download the CCC 11.6 for my Radeon HD 4850.

Everything went well until the update stared. A few seconds after the beggining a blue screen error appears. After reseting I tryied to uninstall the old driver and then another blue screen appears.

Ironically the bluescreen tells me to update the drivers (that's exactally what I'm doing)

What should I do?

delete the driver and try to install again fresh

I can't. When I try it the blue screen appears

[serio]

it might be the time to reinstall your system then.
