Very strange bug with video card

[koko7833]

Hello community,

I'm getting a very strange and uncommon bug when i play video games. When i'm playing something suddenly the only thing i can see is vertical lines in two colors (every time is different) alternately. After that my i can hear a buzzing sound and my pc restarts. If the game i play requires more performance from my GPU the faster it happens. My PC is not so bad : CPU - Amd A10-6800k, GPU - Sapphire AMD r9 270x, 8gb 1600 mhz of ram, Samsung SSD 850. I'm with Windows 7, but i had the bug on Windows 8 before too. I never saw a bug like this and i will be very thankful if somebody can help me fix this.
P.S : This is an image i made in paint to help you understand what i see, because my English is not that good.

Sounds like artifacts, and sounds like your GPU is dying an d will be dead very soon xD Are you overclocking? go back to stock. Clean your card.

But yer defitnly sounds and looks like artifacts 😉

I don't understand what do you mean with "artifacts". I have never overclocked my GPU and won't do it. So the problem is somewhere else 🙁 . But i'm not good enough to fix it myself.

Run your integrated graphics (APU) through your motherboard video outputs, if the issue is gone it's your graphics card.

I bought my GPU 6 months before everything else and I didn't have this bug..... So yeah its definitely its the video card, but idk if its serous or not... :/

that's serious, but I would try my earlier suggestion to verify it's the cause.
