Specs:

MSI Geforce GTX 1060 6gb - Up to date driver ver. 445.75

AIDA64 FPU test for 2hr shows stable at ~44-48 deg C


PC has a fresh install of Win 10 onto m.2 850 EVO 250gb w. the necessary pc launchers (Steam, Battle.net, Origin), Discord, Firefox, page file at 12GB, no extensive bloatware. The cooler was cleaned today of all dust disrupting air flow. Normal PC operation shows no error or problem, AIDA64 FPU test stressed CPU @ 100% for 2hrs w. an average temp of 45-50 deg C. No definitive overheating problem. Crashes appear when playing any game, League of Legends, Rust, Modern Warfare (Warzone & Multiplayer). These crashes just stop the game, no blue screen, freezes screen, loops audio. Seems to be very consistent after about ~10-15m of play time. Have not been able to play a whole game of Warzone or 2 full games of multiplayer on COD MW, crashes 15min into LoL games. I have adjusted all settings in these games to lowest settings to no change.

Please advise what I can test and provide results or what further info may be needed. Thank you so much for your time to read my post.
