So whenever i play games and this can range between 5 minutes of playing or 5 hours my pc will randomly freeze, i can hear my friend on discord for 5 seconds then it stays frozen i cant do anything i cant tab out nothing so i have to reset it or shut it down fully using power button. I have tried everything with reducing ram speed, watching panjnos tutorial on how to fix crashes i did the memory scan, no errors and i scanned my pc in cmd, again no errors. I updated my motherboard which did fix some frame drops but the crashing... i just dont know what to do. feels like i tried almost everything. Also when it comes to games it can be someting like cs2 that isnt very demanding or some heavier games like space marines 2!
