Computer keeps freezing when gaming

[villehockey]

So I've had this problem for a while now. My computer freezes ONLY when I am playing a game. What happens is I see small horizontal stripes (normally black and green or black and gray) and I hear a buzzing sound in my headphones. I have to restart my computer when this happens (sometimes I get lucky and it does that for 10 seconds and only my game crashes). Since this bug, I also notices that it take a long time for my computer to start after putting my password (it takes a while before I can launch anything).

Here are my specs:

Processor: Core i3-4170
RAM: 8 GB
AMD Radeon R7 370 Series
Windows 10 but i didn't activate it(my friend got it for free 😉)
Monitor: BenQ XL2411


Thanks for answering

First off you are stealing that copy of Windows and can get in trouble for that.

Your crashes are caused by the video card or the video card drivers.

I suggest you get a legal copy of windows.
Backup your personal information.
format and re-install your copy of windows
Install the latest WHQL drivers from AMD

Also check that the video card is seated correctly and the power connector to it is also firmly attached. Could try a different power cable from your powersupply to the video card if it as a spare lead with the right pin count.

Thanks for the help! I'll look into that!
P.S: I was planning on buying a legit version of Windows.😀
