hello i just made a custom pc build. my problem is that it works fine the first couple of minets and then it just starts to lag every few seconds. this lag includes mouse lag, when it lag what every sounds are on it will just keep repeating it a bunch of times. when the computer is working perfectly i can play games like Darksiders 2, but after a couple of minuets it just goes all laggy. and before this problem there was another problem that i had. the problem was that the computer kept freezing on boot up. but then i fixed this with disabling the onboard video card and enabling the one that i bought.
