Answer 1

Maybe its the fan?

it's a cheaper option to try before you replace your whole computer.

Answer 2

The only moving parts in the computer are the hard drive and the fan,if you already have replaced the hard drive then the only thing left is the fan is begining to go

Answer 3

change your whole computer.
