RE: DELL precision m4800 freezes/hangs randomly for 5secs or so and recovers.

I have the same issue here with my M4800 UHD 4k screen version. The freeze does not happen when docked on a external monitor(4k external monitor). But constantly happen randomly on my laptop screen. Dell replaced logic board 2 times. and replaced video card 1time. System upgraded to Win10 and reintalled again and again. All drivers are new.................................................... Machine still freezes few seconds every now and then. Really annoying. seriously affecting my working with this laptop.
