Chosen Solution

Hi guys and girls..:) so, about a month ago, i decided to build my self a New pc. I’ve put it together myself as I’ve done that multiple times, so it’s no issue - and the PC’s running fine most of the time.. However, when i play games (AC3, MW, CS GO and the likes of that) my PC freezes to the point where i have to force reboot it.. The error manifests after everything from 2 minutes to 3 hours.. I’ve taken it apart and put it back together again and checked for bent pins on cpu, badly seated ram/gpu, did memtest86 turning back no errors, stresstest the cpu for hours - no issues, done benchmark and stresstest on gpu with no errors - and still it craps out Every time.. It’s quarantine season i’m sure my girlfriend would appreciate any help you guys can give as I’m losing my mind here..:D posted picture of hardware list as well..:) Fractal Design: Node 304 Intel: i5-9400F (6k - 4.1GHz) Noctua NH-L9i Asus STRIX Z390-I Gaming AMD RX 5700 Grafikkort MSI MECH 8GB 16GB 3200MHz Kingston HyperX Fury 512GB Intel 660p SSD 3 fans in cabinet Ram’s set to run xmp SSD is nvme Thanks in advance - stay safe!!
