So i have problem with my PC.After some time gaming my PC freezzes and starts buzzing.Frist i tought that my CPU is overheating so i swapped my thermalpaste.but that did nothing then i changed GPU thermalpaste but that did nothing as well.So i decided to buy a new GPU because everything worked well with integrated GPU.But changing GPU did nothing again.Then i suspected PSU problems so i bought new PSU but again nothing.
