so i bought a RTX 2080 used about 8 months ago. All of a sudden it started acting up, so i open gpu-z to see what's happening. its Perfcap pwr at idle, and power consumption is way too high. I've DDU and reinstalled the latest drivers. updated to the latest bios, and nothing has changed. Every time i boot up, it's at perfcap pwr. Any ideas as to why?
