My computer experiences random freezes. Windows 10.

Hello everyone.

My self-built PC experiences random freezes.

It is an Athlon FX6300 + Asus M5A97 motherboard and a MSI Radeon 270 GPU. RAMs are Corsairs.

What i mean by freeze?
If i am playing a game the picture suddenly freezes and i hear a continuous sound where the music or sound stopped. I got no BSOD and there are no strange sounds or alike. I never tried waiting longer then 1 minute to see if something happens. The numberlock is unresponsive as is mouse and keyboard. A reset restarts the PC without Issues.

I ran Memtest 86 for 26 hours and it turned out with 0 errors or warnings. I made a crystal disk scan of my harddrive and it says its "Good". I tried different RAM and the issues persist. I have no option to try different Motherboard or CPU.

My PSU is a 650W Corsair.

I run a USB mouse and keyboard. Both plugged in from rear into the case.

I checked out all connections and it seems fine. Reseated all power connections, tried different RAM slots.

I ran a sfc / scannow and it turned out good.

I ran the DM Log collector and have attached the generated file.

I have a feeling that a fresh installation either doesnt fail or fails quite seldom. The PC crashes mostly while playing my favourite Game Farming simulator 2015, i tried running it with a system monitor up and there were no signs of overheating or similar.

Any help would be nice. I hope i posted all according to the Posting instructions., If not i am stupid and will correct it.

Additionally, i am experiencing many warnings in the Event viewer. Some of them are "Critical" "The system was not shut down properly" etc. Most other are warnings about processes i dont know what are they doing. But i dont know how to post the results here.
