Hello guys
I was watching Youtube and checked Speedfan and I saw that my GPU temp was 55 C so i turned on MSI Gaming App because i wanted to turn off Zero Frozr off to cool it down. And when I clicked on the app, the monitor got weird flickering lines with pink and green colors and monitor screen showed no signal then again the lines, no signal, lines then the pc got BSOD and restarted. Then the screen got normal but i turned the PC off because i was scared of it. Also i heard some noise coming from my PC. Few days ago i bought new PSU and couple weeks ago i bought the RX 470. For any help thanks.
My specs

Windows 10

AMD RX 470 MSI GAMING X

AMD FX 8350

Corsair RM 750x

12GB ram

ASROCK 970M PRO3

Solution
Your GPU or monitor might not be connected properly, try taking the GPU out and instert it correctly in again, and make sure are the cables are connected well, also do the same with GPU to monitor cables.
