full pc freeze did happen during dota 2 match and this is first time.
Last 6 months I did not have any problem like this in dota 2.
Only change is new cpu and sam enabled and I played around 20 games without problem. Dota 2 is very smooth now with new cpu.
Yesterday I did unlimit fps.
Company of heroes 3 have similar problem with full pc freez and it will happen once after around 20 games and I did contact game developers and they did confirm existence of problem and they work on fix.
My report about same problem but in company of heroes 3
