I have a Dell Inspiron 5100 laptop (running xp with sp2) and I need to replace the motherboard. Because I have no clue when it comes to computers, how exactly should I go at this? My friend said he could fix it for me if I ordered a new one however I have no clue what to order. I checked out newegg and had no idea what motherboards were compatable. Can someone recommend a site or specific motherboard that would be compatable? Or is it even worth fixing? Dell said they could fix it but it would be about $500... should I go with that? Thanks in advance
