PC freezes with strange noise

No matter what i'm doing (playing games or movies or music).....it's the same sound......always...the sound doesn't change

and if my pc is left unattended (like if i leave my pc on and go out) for a long time it just freezes up but when this happens that sound won't be heard.....

THIS IS WHAT THE LOGS SAID....I DON'T UNDERSTAND THESE STUFF
