I can't seem to get the CPU off the motherboard to replace the motherboard. I've unscrewed the 4 screws on the outside but it just is stuck there. I've pulled and pulled but still nothing. I don't want to yank too hard and risk damaging the CPU. Any help please.
I am not sure what you mean by "4 screws on the outside" to get the CPU off the motherboard. Maybe upload a picture. That Vostro model uses a latching system. Are you talking about the fan on the heat sink?
