So this started happening randomly to me like 2 or 3 days ago. It happened first while playing csgo mm, then i played some dirty bomb and it happened as well, and it's happening on tf2 as well, so I know for sure its not a game specific problem.
I checked temps on my pc and processor and everything seems to be normal temp. This is really annoying, never happened to me and I have a decent pc so it definitely shouldn't happen. It just freezes/crashes completely for 5-10 seconds and then unfreezes and usually some keys are not working when it unfreezes so I have to alt tab out and in of the game again for the keys to work.
