My radeon 4850 will not take updates. Let me clarify. I'm not sure why my radeon 4850 will not take updates. After updates to the driver have been loaded the system just crashes and the computer goes through a whirring noise period sometimes starting and restarting again. Once the drivers have been rolled back, the system works fine. Any ideas or next steps? Thanks in advance
Download and install Driver Sweeper from phyxion.net, uninstall your current drivers, reboot and go into safe mode, analyze and clean all ati related drivers, reboot back to normal and install the latest 11.12 catalyst.
