So I've had this issue for a while now and I have tried everything apart from replacing the HDD because it's expensive business and I want to eliminate all possibilities before I purchase a new one. I have disabled all the known services to potentially cause 100% disk usage, I have ran checks on the storage drive as well as making sure ALL my drivers are up to date, I have made the necessary changes in settings to Chrome/Skype and I have also reset my PC and reinstalled Windows. So at this point I'm kind of at a loss. I figure if I can't find a fix then it may be the HDD and I should look to swap it out for another HDD/SSD. Any help or ideas would be very much appreciated, thank you.
