Since all of your drivers appear well to me, I'd suggest to make sure there is no overclocking on any components, whether it be CPU, GPU or RAM.
I noticed you have Afterburner or similar overclocking tool installed. I would uninstall that (also because driver is 2011) for now until this is all figured out, to get rid of the driver and also to ensure it doesn't have a setting applied at boot to overclock.
For good measure, use CPU-Z to compare SPD tab to Memory tab. See if your memory is set well as it should be with regard to timings and frequency.
This driver might be a little suspicious as a possible culprit, based on the fact that I've never seen it before and there is little information:
Perhaps look into removing the software that owns it.
