Dell Inspiron 5548 blinking screen when using wireless card

Hi,

I'm bought Dell Inspiron 5548(i7 CPU, Dual Video card and 1TB HDD) few months ago and faced with one problem, when I'm using wireless connecting(e.g. watch online videos, downloading files), screen starts blinking. When using Ethernet or wireless USB adapter everything ok. It happens to me with different linux distributions, I've tried Ubuntu 14.04, Ubuntu 15.10 and Debian.

Please help,

Arthur
