Went to use my computer this morning and everything was as usual. After a few hours had a BSOD with a whea_uncorrectable_error message. After I forced a shutdown and booted back up the computer ran extremely slowly. Programs will take several minutes to load, cursor is jumpy and slow, difficult to access things due to the slow response. Windows event logs showed a kernel power shutdown error with no other relevant information. Idling at the desktop I have 3% cpu usage, 12% memory usage, and variable but nearly 100% disk usage on the ssd. I ran HD Tune benchmark and smart info, screenshots below, but nothing seems off to me. System is a 4770k at stock, 32gb ram, samsung 500gb ssd, evga gtx 1070.
