I've got a strange problem with receiving freeview. We live out in the sticks a bit and shouldn't really get freeview but we do fine. However it seem's whenever I turn on this computer which I belive is near the aerial in the roof we loose ITV1, channel 4 and things like ITV2 and E4. The signal complety goes and seem's to be ok when the computer is on. However we can still get BBC1, UK TV history e.t.c. Anyone know how I can solve this? I can't move this PC anywhere and moving the aerial in the roof will be a problem. We do use a signal booster but not sure if it's any good or if its working as well. Anyone suggest what I could try???
