How old is the graphics card?
How hard have you been pushing it in the past?
There are two things you can try, (both might be good ideas):
- Revert the NVIDIA driver to the older version.
- Refresh the heat-sink compound on the graphics chip. Graphics chips, like CPUs, need a periodic refresh of the heat-sink compound because, as it gets older, it begins to dry out and loose its heat conductive properties. I try to remember to do that at least once a year - more often if I’ve been driving the system hotter than normal.
Another thing you can try is modifying the fan profiles. In my case I have modified the fan profiles so that all fans, (GPU, CPU, and case fans), always run at 50% below about 50° and ramp steeply to 100% at 60°. This helps keep the CPU and GPU cooler and - as a consequence - running better with no glitchy problems.
My GPU and CPU fans were originally set to zero% up to about 40-or-so degrees, which they rapidly rose to - and exceeded - bringing the fans up sharply. When I set the base speed at 50%, they’ve never had to go beyond that. Also note that I am using standard fan cooling and no overclocking.
