had nvidia 9800GT for two years no problen until recently graphics all over the place screen locks up ,weird noise from machine.windows error says driver problem tried driver roll back it works for awhile then back to problem. any suggestion please.
did you install the new driver over the previous one? btw you can try using driver sweeper. uninstall the driver and run the driver sweeper in safe mode to clean the left over from nvidia driver. then install the latest driver
