Hope someone can help.

I have a late 2009 imac with Yosemite installed. Used it for years without any issues and finally upgraded so was looking at selling it.

I did a factory reset and installed Yosemite with a bootable USB which I've done so many times in the past excpet this time I'm getting the mac error noise every 30 seconds or so. The mouse also has a life of its own and scrolls down on a Web page on its own and flickers constantly.

Weirdly the main enter key stopped working and i know for a fact it was working before, the small enter key on the bottom right works fine.

Tried to reset a few more times but no luck.

I've tried the original apple mouse i have and also a Logitech mouse but i get the same result.

Hoping someone can help?
