Why your keys stop working on your computer all of a sudden example(q,s,a,and g) then the problem is is that your computer is maxing out the power supply and you need to get another one to fix this issue. Power supply’s needed for the gt 1030, 1050, and 1050ti is 400w. Gtx 1060 is 500w. Gtx 1070 and 1070ti is 650w. And 1080, 1080ti, titan x, and titan xp is 800w. The reason for this is when your power supply gets maxed out then the computer will start limiting services to save power including thing the gpu can do. If you want to fix this problem for free then go to power option and select the power save mode this will slow everything down without letting the gpu being the one slows down but this free way will take a 1060 to a 1050 level of performance so just spend the extra 50 bucks to buy a 500w powersypply so you can game at full level.
