1. open your control panel, programs, uninstall program, and UNINSTALL NVIDIA display drivers.
2. reboot your computer, upon start windows will install an older driver for you video card, just let it be.
3. Start CCcleaner and let it run. It will clean a lot of registry entries that are absolete.
4. Uninstall the video drivers again windows just installed (trough device manager or programs/uninstall)
5. reboot your computer in SAFE MODE (else windows will upon start reinstall some drivers by itself)
(safe mode by pressing F8 on start)
6. now in SAFE mode , install the drivers from your brand/model.
7 reboot normal
I've successfully tested this for over a week now, ran a lot of applications and games together to stress it to the max , and the problem has not occured.
Meanwhile I would still URGE TOSHIBA to release a newly updated proofed display driver. It has been long enough, won't you think ?
Re: Qosmio X500: "Display driver stopped responding" - SOLUTION
in response to: EdBelgium
I installed latest drivers from the support site, altough they are over a year old.
It has also come to my attention that some badly programmed applications reinstall registry entries for the shared dll files from the nvidia/ati video drivers. So you might want to run CCcleaner on your registry once in a while to see if they aren't back in there, else it will regenerate an error.
