Hey, i was playing some games, so i alt+tab'd to check my gpu temps with GPU-Z and my computer freezed, after i restarted it, i opened gpu-z once again and pc freezed again.
After that i used afterburner to check on temps and i got this really weird gpu usage/temp:

Why could the GPU usage bounce that much while i was only using chrome? Also, i'm kinda worried 55°c while only using the browser, normally it's around 45°-50°, did gpu z f*** up my gpu or something?
