Hello, i just built a new PC last night and I'm having a number of random issues. For some reason after maybe a few hrs, my system starts to lag lukr crazy the mouse is choppy when moving arround if im watching a video the sound starts lagging and getting robotic and cuts in and out, programs start to lag and say waiting for response. Then the screen goes black and I have to restart the computer. Im using windows 8.1 on a 240GB SSD.
