BSOD while playing CS:GO and other games before

After getting my uncle to reinstall Windows 7 for me,, I'v had about 4 BSOD's recently. All of the BSODS happen when I'm playing a game, and I thought first it might of been because windows 7 was out of date, so I fully updated it and got a more stable version of my driver, but not too long after that I started playing CS:GO and it got a BSOD. No idea whats going on. My computer worked perfectly fine with no BSOD's before reinstalling Windows 7 which is odd. Most of the time it got a BSOD it was because I alt tabbed out of the game.

Thanks.
