MegaCool wroteMy guess is its either overheating for some reason ( I recently overclocked my card, but for obvious heat reasons, I received this message numerous times whenever I access 3D applications or games) or it might be a defect card. I doubt that it's a driver issue.
Anyway my suggestion is to completely uninstall the nvidia driver then reboot and re-install the latest one. If it didn't work then there must be something wrong with your card.
Yes but if the issue appeared with the installation of the latest drivers, then he should rollback to the recent most stable ones...Such drivers are known and mentioned in forums...such as 258.96 for example.
Now his problems was from the start and increased. So it's most probably not a driver issue, as you said.
@Kassem: Take out the card, dust it off with a dust blower, clean the cooler from all sides with the blower, pop the card back in, and you should be good to go. Raise fan speed if necessary:
RivaTuner
MSI Afterburner
EVGA Precision
These are all good software for raising fan speeds.
Please don't forget to report back what fixes work and what don't. We might benefit too.
