I've my GTX 970M working for a good while, but I decided to re-apply the thermal paste today because my card seemed to get a bit hot and my gaming would suffer from fps drops. I figured re-applying the thermal paste would work, but it didn't. I then uninstalled the drivers and tried reinstalling different drivers to see if they'd perform better, but for some reason my FPS is constantly below 60 FPS no matter what game it is. I've tried checking my settings in nVidia control panel, I tried flashing the vBios, I've changed countless settings to try and make it work but nothing is working. I also noticed that when I use Speed Fan, the GPU section doesn't consistently show my GPU temps. It stays at 0 Celsius for the most part, but then randomly reads 47 Celsius.
Any ideas of what could be wrong or how to possibly fix this?
