Clean installation means, formatting the hard drive and re-installing the operating system as if it is a new system, that means losing all data on the hard drive, hence it is recommended to perform a back up of the data before doing the clean installation of the operating system.
Perhaps you can test the processor on a friend’s computer or by taking it to a local computer store to be tested.
