im using alienware alpha r2 with alienware graphics amplifier(gtx 1060 inside),  my games run smoothly before but now my fps started to drop and my cpu usage is 100% and my gpu usage is just about 3%, i tried some games just using my alienware alpha r2(not using the graphics amp) and the game runs smoothly, pls help!!

i tried updating bios, updating alienware graphic amp software, set power management mode to prefer maxium performance in nvidia control panal, reset pc but nothing helps
