The CPU is mounted correctly - It keeps the CPU about 30-40 degrees when not playing. I watched videos to mount it correctly

I can start the PC and run it for some time, but when i start an application like call of duty or something, the pc just freezes till i hold the shutdown button. The whole monitor just freezes and my discord also stops at the same time.

Hey forum! I recently bought a brand new PC and build it. The new parts are very new compared to the old ones from my recent pc build. In my new PC, the only thing that i still need to replace is the GPU. I am waiting for the new Geforce 3080 to arrive and meanwhile i just plugged in the old GPU from my previous PC. This GPU is a Nvidia Geforce 1660 OC New PC specs: 1: ASUS ROG Strix 1000w PSU 2: Kingston A2000 1TB NVMe M.2 SSD 3: HyperX Fury DDR4 3200MHz 32GB 4: NZXT Kraken X73 CPU Cooler 5: Intel Core I9-9900K processor 6: AORUS Z390 PRO Gaming Motherboard and 7: Nvidia Geforce 1660 OC Could this be the reason why my PC keeps freezing? To plug in my old GPU (Nvidia Geforce 1660 OC) with the other much newer parts?
