If you have an nVidia based graphics card and have recently installed the 196.75 version of the drivers, make sure you roll back to an earlier version as soon as you can.
Engadget is reporting that nVidia have pulled this version of the driver from their site due to reports that it is causing a fan malfunction causing performance issues and in some cases graphics card heat death.
If you have recently installed this version of the driver, it’s a good idea to rollback to an earlier version. Despite the inconvenience, remember that graphics cards ain’t cheap. At the very least it’s probably worth your time (if you own a card based on the nVidia chipset) to check the driver version, especially if you’ve installed any new games lately. Or if you’ve updated your drivers recently.
If you’re like me and last updated when dinosaurs still roamed the Earth, you’re probably okay.
