I reached out to Paul after getting his number as a computer repair service near me in Northbrook…read more I have been frustrated for close to six months being traded off from Microsoft support to Xerox printer support. Each telling me that the problem I had in not being able to print was the others fault. Friends and family all offered suggestions and possible solutions that only caused more problems with my system. After calling PAK, Paul spent several hours trying to figure out the issue and low and behold, after I left my desk, he found the corrupted driver causing all my problems. He did a great job for me and though I hope I have no more issues with my system, he would be the first person I call, if it were to arise.

Let me paint a picture for you all:…read more Friday morning, I sat down in my hotel room in Champaign with a bit of breakfast and my laptop balanced on the arm of the couch. The computer fell back, hitting the floor and popping the glass screen out of the shell (rendering the computer completely unusable). Four hours later, I made it back to Mundelein and brought my computer to the Computer Guys. Three hours after that, the Computer Guys called me to tell me my problem was fixable, how long it would take, and how much it would cost. The next morning, I received another call to tell me it was ready for pickup. I got to the shop, verified that my laptop was up and running, and I went on my merry way, fully-functioning computer in hand. In less than 24 hours, my computer went from functional to broken to functional again, and I couldn't have done it (and done it affordably) without the Mundelein Computer Guys. As long as I live in the area, I won't go anywhere else for my computer-related needs.

Steer clear away!! This business used to be very sensational on repairs, turn-a-round times, and…read moredown to earth friendly responses. I worked with Matt thru 2019. Went back Nov 2025 and now with new owners. Left a laptop to remove a password which they said no problem. Would cost $75-$100 per text. Any voice messages received are returned the next business day. Well 3-weeks later I had to drive to the store since they do not return phone calls or texts. They stated it would be one more week and promised to relay info on texts. Found out they are extremely unprofessional and quite opposite of transparent. I ended up at the store to pickup my laptop two weeks later. They acted as they didn't understand the language so I advised if they do not return I can easily involve the police down the street. Well funny how they understood that statement. If you can't take care of the most simple task of responding to your clients, then I refuse to give you my business.
