My computer is barely functioning. It is freezing up all the time and just really slow. I recently got Windows 10 but it was running slow and freezing before that and it hasn't changed or improved after installing Windows 10. My son cleared a lot out off the computer and I do not think he reinstalled or did everything necessary to bring the computer back after he cleaned the hard drive. He did this without my knowledge after he forgot his password. I know the computer is missing many drivers now and who knows what else.
