Skybird,
Google "Computer Power Conditioner."
IMHO, you don't need to spend a lot of money for one.
Go to this site and read:

An excerpt form this site: Power line disturbances can destroy, degrade, and disrupt electronic systems. Plug-in
surge strips are only capable of reducing surge energy — not eliminating it. Plug-in
power conditioners that include a surge diverter, isolation transformer, and power line noise filter in their design
can eliminate system destruction, component degradation, and operation disruption by exhibiting much better control over surge voltages.
