Do not replace a motherboard or anything else on a 9 year old laptop. It has served you well but it would be a waste of money to do any repairs on it. Put the money towards a new computer.
Hi Mary G
Thanks for your reply. I am also considering the same option to abandon my laptop but then I get the second thought that getting a new motherboard will make my laptop as good as new because I have no other issues in this laptop. Replacing only motherboard more economical solution then replacing the laptop. Please tell me why do you think I should not invest in replacing motherboard only? Any technical reasons?
