Problems with constant crashing and Blue screen of death

[Razokin G]

I am having a lot of trouble with my computer crashing games or going into the blue screen of death while playing games such a GW2, War Thunder, and even older games like Republic Commando.The games will either just randomly crash, completely freeze up until i restart the computer, or go into the blue screen of death and reboot. I have tried updating all of my drivers that i am aware of and I cant tell a difference and i honestly don't know what to do anymore. Any suggestions or solutions would be greatly appreciated!

Any over locks applied? Under volting can cause you to case blue screens

I have no idea, where do i need to look to ensure that all of my components are receiving enough voltage?
