I have a problem with the alienware I thought it was the videocard i tested 2 other cards and still the same problem its like a snowy screen !!!! other things i tried : Switched memory,bios update,tried an other screen , on hdmi also the problem .On the ecxternal monitor it works FINE!!! Also the test with F12 so`s no videocard problems...Does someone know what is the issue? Is it the cable that is corrupted then im thinking why hdmi is not working.
