If the new mobo is the exact same make and model as the old mobo then it's just a matter of moving a few parts from old to new.
Before you do this look at the bios level of the old mobo.
After the swap look at the bios level of the new mobo.
the wifi and ethernet chip on my current motherboard is broken, so my computer gets no connection to the internet through both wifi and an ethernet cable.
I'm thinking of taking old the broken motherboard and replacing it with the same one as before but a fully working one, will I need to replace any parts I have already?
