Callisto Computer Systems

Your first call for business and home user PC solutions

If you have had your computer for some time now, you may well be experiencing problems such as lack of memory, not enough disk space or just a general slowdown as you try to run the latest software. Callisto Computer Systems can upgrade your system quickly and easily.

You can supply the parts yourself and just pay us the labour or let us supply parts and labour. The choice is yours. All parts that we supply are covered by the standard 1 years manufacturers warranty. Should any part that we supply fail in that year then we will remove the part, return it to the manufacturer, and refit the replacement totally FREE of charge.

Free upgrade consultation.

If you would like to increase the performance of your computer but are not sure what you need, then time permitting, we'll look over your computer and give you our recommendation for upgrade.
