I have this weird issue that has been getting progressively worse the last month or so. My PC has been freezing (either ERRR noise or simply froze in time) or shutting off like someone is pulling the plug out of the wall. Most stressful thing this does is watch HULU / surf the web. It will freeze about once or twice binge watching a show. If your lucky you'll get through a show or two.
Circa 2014 build in a Corsair 200r case
AMD a-10 5800k (not over clocked) with Hyper 212 cooler
8gb Ram (Should be good)
Gigabyte mATx Board (Latest Bios - Reset to defaults)
HD 7870 2gb card (same issue using onboard video or card)
Seasonic 750w PSU (brand new replaced original PSU same issue)
CMOS battery (Brand new)
Lots of HD's/SSD's (HD's pass windows/ SMART / diagnostic tools I can throw at them)
Video (replaced with latest)
onboard Network card (replaced with OEM drivers)
PC to TV connected via 25ft HDMI cable.
Windows logs show "improper shutdown occurred" but I guess that's all I see. My only guess is the system is overheating, but I don't know why or how. Fan's (4 - 120mm) all work and its been cleaned properly configured airflow direction. The computer sits in a cabinet with the full back removed so there should be plenty enough airflow.
Software recommendations to track temps?
Any other thoughts on what to try?
