Reference to the above Title , when I am typing for 10 -15 min suddenly the mouse & keyboard hanged-up , everything is freezed . the only way to dislodge
the freez is by pressing the keys ( Alt ) , ( Ctrl ) , ( Del ) simultaneously , But doing so
will erase everything I typed , note that this happend while the internet is on .
What is the problem with these devices ?

Best Regards
