I have a dell 8200 inspiron wirless card started acting up ..shutting down eventually wouildn't even read it so went to hard line and now when it starts up or I "plug in" it says "new hardware found" but as it goes through the install it says there is a ethernet control problem as in a driver needed. but when I look in systems I have a big yellow ? mark by the ehternet control any suggestions? Is it the motherboard or something else? I've tried to restore it to a date it was working but no go!

Help Please!
