This is also the situation with the HD. Heat is the enemy of electronics. Check fans, air flow, and dirt/dust. Clean the unit and relocate it so that air flow is unrestricted. Replace any fans that may be getting sluggish -- fan bearings do wear out. If properly maintained, electronics can last indefinitely. Heat can easily cause CPUs and disk drives to malfunction. If caught early, there may not be any permanent damage, but if left unattended to, you may wind up having to replace parts. All of the above is especially important for 'small box' systems like yours.
