just want some quick help. not looking for anything in depth, surface level "it could be this or that". my PC hard crashes, powers down completely, monitors stay on, rgbs are the only thing on the system that stays on. i've had no BSODs or dumpfiles created. all components of my pc i have tested in dependently on a test rig but combined together the system crashes ONLY during video games. quite literally only video games as it's not crashed for stress tests like cinebench or heaven benchmark or anything else that's cpu/gpu heavy. the crashes are super sporadic and hard to nail down and replicate, it could be after 5 minutes, 10+ hours or not at all. everything has been reseated & cleaned. psu volt rails have been checked, different outlets, ups too. i've done all the "update drivers/bios" garbage, sfc/dism/memtest/etc. ram isn't mismatched. anyone experienced this, if you did how did you fix it or is there any advice that could be given? been troubleshooting for a week and i'm just at a loss.
