Many times, people ask us if they should turn off their computer when not using it, or if it is safe to leave it on overnight. Everybody seems to have heard something different about this one. The truth is, it is absolutely safe, and in some cases even recommended to leave the system on all the time.
All versions of Windows have the ability to schedule tasks such as clean the hard drive, defragment, and other chores. Our suggestion is to leave your system on 24/7, and schedule these tasks to occur overnight while you are sleeping.
