CPU

Hi, i got some problem that i cannot understand what is the error / broken hardware.

It’s on 3 days ago, when i was playing game ( PUBG ) my pc started freezing a second and then blue screen appear ( with a white scratch / it’s like bunch of brick ) and then it’s restarted itself. I have no idea why and so i turn my pc on, nothing happen, even it’s not get in to the windows.

The next day i tried one more time to turn my pc back. It’s started well ( i could get in to the windows ) and i started to do things, such as playing game again, nothing error appear.

And this day, i was turned my pc again, It’s started as well as 2 days ago. But, when i was playing game, it’s started to freezing again and then the bluescreen appear again with same scratch / brick lol, i have no idea why, then i just turned my pc on again, nothing happen, just black screen, its even doesnt get in to the windows.

Please help me, i have no idea how to fix it, even i don’t know where the error is.

Sorry for bad english.
Thanks in advance
