Earlier today i was playing a mmorpg then my screen frooze, keyboard responded but i couldnt tab out from fullscreen. checked temps after they are fine with cpufan, all 4 cores stays at 47-50 in load the rest between 25-45, note the pc more than one year old, the coolers are still clean i checked them right after game locked up and i had to do a hard reboot. this is what i call a software freeze, if the computer freeze i havent had any the past year, the whole thing locks up, keyboard aswell. i just formatted for the same reason had to do hard restarts forgot to run the checkdisk it recommended and i got the read error upon startup. Anyways now windows and drivers are installed it seems to work fine, it never freezes in windows ofcourse, i only had one freeze so far since yesterday format, but freezes never seem come alone, when i get one i always get more sooner or later.
