CPU: Intel Core i3-6100You should post more info. What specs, game and settings. Does this only happen in one game or more? Did you have this problem before?
nope i ctrl alt del and i see evrything i want from thereWhat are you using to monitor the CPU usage? Wild guess: Do you alt-tab to see the taskmanager and the usage spikes?
Update your drivers and stuff and see if that helps. Can you list any of the games you play. You say that the CPU stands at 13% when not moving your mouse, that's wierd, I'd expect more usage than that, but I don't know what game it is, so who knows.
Did you buy the PC pre-built from a retailer? Recently bought I imagine since you report the problem now.
