I contacted Cybertek when my PC was having all kinds of errors. They came out and fixed my problems that day. I have since had them put in more RAM, a new video card, & several programs and games I purchased and they set it all up for me, made icons and customized my whole PC, hardware & software. They were always on time, courtious, and understanding. They even took the time to explain to me in terms I could understand what they were doing, why the bad stuff was happening to me, and how to protect myself in the future.
