So i have an old laptop way back from 2011 every hardware on it was not change even the HDD is what was originally install so the HDD got two partition one windows the other one was with just files so i formated the windows partition and reinstalled windows everything was working tile programs become corrupted by a few kilobyte around 10kb causing error 0xc0000005 and thing like windows defender is stop for some reason and in the folder option the “show system protected files” instead of the checkbox it has a pernament circle and only way to turn it off is using the registry.

So I’m asking could this be HDD releated problem cause the drive is 10+ years old and i havent deleted the data partion E: not C: so it probably have a malware or something or is it something else.
