yusufoozturkSo you're saying your problem was cooling? It's just that for me, it seems, it is not connected with cooling, since the bug also manifests itself at low temperatures in the absence of any load. + My pc is still completely new (1 month), it stands on a cooling pad, there can be no talk of any dust or dirt. + I would not say that it gets very hot for me, only once I saw a temperature of 94 degrees, and basically in any games it heats up to 85-87 degrees.
As i can see in your videos, your problem is a little bit different than mine. I've sent my pc to asus service and they cleaned it up and repaste the cpu,gpu. Tuf models suffer from insufficient backplate cooling desing, there is not enough room for air to get inside. So it's thermal throttling mostly. I clean the fans by myself now, trying to keep the dust away and in some heavy games it's stuttering for a second, rarely.
at your 3rd video, the SSD seems suspicious to me, better check it first. And clean the fans, if your warranty continues, send it to the Asus service for detailed cleaning. Also use the drivers from Asus's website. I only use the newest drivers from amd and nvidia's website for gpus and chipset. The rest from the Asus.
