I installed the OEM Win 7 as a clean install after upgrading memory, installing CPU had lying around, can not activate OS because the product key is not recognized as legal. I reformatted the HDD and reinstalled the OS, but to no avail. Have attempted to contact MIcrosoft, but the wait is so long, that I never get anyone to connect with me to solve the problem. This is an old Gateway machine that still works well for my wife, I don't really want to spend any money on further upgrades unless I absolutely have to. The system originally had XP on it. Do I need to replace the HDD or just build a cheap system from scratch, replacing the MOBO, HDD and GPU
