When my computer monitor, keyboard and monitor failed, I looked to HomeStars for help. I contacted ProTech because of the many good reviews from Mississauga. Richard answered my call immediately and picked up my desktop tower within a few hours. He replaced the Motherboard which had failed and a few other items which needed replacing. When he returned the computer to me, he set it up and did not leave until everything was in perfect working order. Richard is a true professional, pleasant, honest, helpful and he went out of his way to please and provide excellent service. His price was very reasonable in my estimation. I highly recommend Richard and ProTech to anyone who needs his/her computer repaired.
