I went ahead and backed off on my GPU OC. It's too hot right now anyways.
It's completely random. Some days I can go all day without a freeze, others I'll get a freeze in an hour or two. I've even had it freeze within minutes of joining a server.
Oddest thing happened today when I started it up. It had frozen last night and I just shut it off and went to bed. Started up this morning and opened 2142. Everything was fine until I joined a server, then I had no controls. Mouse, keyboard, nothing. When I had started 2142, my login info wasn't inputed like it normally was and my clan tag was missing, didn't think anything of it until this happened. I finally checked the controls settings and everything was wiped, had to reset back to defaults
