So I couldn’t turn my pc on. I went in to unplug the GPU and when the on board graphics card wouldn’t work, meaning I plugged in the screen to the motherboards GPU since I took mine out, I decided to put the GPU back. Well when I hit the power button the cpu fan sounded like a helicopter about to take off. So I decided to just take it apart and make sure the CPU has enough thermal paste and that the cpu fan was sitting properly. Well took out the Fan first and then I couldn’t find my CPU. I know right wtf was it running on lol. Well it’s like cement stuck the damn CPU fan. Help!
