Upgrades and Repairs 
Our technicians have
extensive experience with a broad variety of computer systems, and are
expert in diagnosing and fixing problems. Many repairs can be
done on-site, with no need for you to disconnnect your system and cart
it into the computer shop. If our technician can't diagnose and
repair the machine on-site, or if the repair would be better done in
our workshop, he will advise you of that. He will then
transport the machine to our workshop where it will be repaired
and tested, and then return it to your premises and set it back up for
you.Twin Cities Computer Services can also supply a wide range of upgrades, including memory (RAM), additional or replacement hard drives, dvd burners, lcd monitors and tv tuners. Many of these upgrades can be done on-site.
