I have recently upgraded my computer to an AMD fx-8350 3.52 ghz processor and a XFX r9 270x, and it originally had 8 gigs of ram. what I did was move the old hdd over so i didn't have to deal with transferring all of the data over, and everything seemed fine at first. But when I tried to play Crysis 3, Skyrim, and Dishonored, after a few seconds of gameplay, my entire computer crashes. But the interesting thing is that when i play AC4 and Minecraft, they work perfectly fine. I have the latest drivers for my gpu, and i asked my friend how helped me upgrade it and he has no idea, so i need some help.
