Computer Solutions, Skokie

For 20 years, the experts at Computer Solutions have been servicing and speeding up the motherboards of devices from Dell, Gateway, Sony, and Toshiba. Well-versed in the minutiae of Windows operating systems, technicians provide proactive 24/7 monitoring, data backup, system tune-ups, and data-recovery solutions. The all-purpose tech company offers free pickup and drop-off within 10 miles of its Chicago and Skokie locations, but levies substantial charges for computers that arrive strapped to the leg of a carrier pigeon.
