So i restarted my computer the other day and noticed that my framerates were very sluttery and inconsistant. i ran furmark and it reports that my gpu clock is throttling at around 300 to 180 instead of the intended 750. i tried things like restarting and changing graphics drivers but it didn't help in the slightest. i even tried overclocking but that just made it a constant throttle instead of once every .5 seconds.
