Title basically explains it, had a power outage or surge a couple months ago (happened in the middle of the night so I'm not sure which), but since then it will randomly freeze and the CATERR light will turn on. For whatever reason it's only happened when I'm not stressing the system (mainly web browsing when it occurs). I go and play games or whatever like normal and its like nothing happened. It will also go like 2-3 weeks without it occurring then randomly it'll freeze.
Specs: All has been running fine up until the surge/outage, no overheating...etc
