I am running windows 10 on an i7 4790 3.6 which i have overclocked to 3.9. Would it being overclocked cause my HD to spike to 100% usage and cause my computer to lock up? I have disabled and got rid of Search and Fetch for nothing to happen, I have also disabled antimalware auto startups as another suggestion to not being fixed. I recently reinstalled windows 10 to my hard drive that fixed the problem for 3 days only to have it start doing it again. What could cause it to revert constantly to this problem?
