So i've been using my integrated graphic card from my intel g4560(hd610) and now i bought a second hand car which is amd hd 7770.After a start with the hd 7770 i thought about playing some games ex.fortnite,gta V and yeah,but suddently my pc freezes and i heard some weird sound from my headphones.So my question is-is it that my psu is not handling the gpu.My PSU is Powerbox 500w(it's made in china)
