Recently my computer has become really laggy and unresponsive(applications, folders, and tasks can take several minutes to open or register). This usually happens right after startup. Ive reset/wiped my computer a few times and it fixes the problem but it comes back after about a week of use. i noticed on my task manager that the disk tab is red and at 99-100% when this problem starts.
