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.

I went there bc my mac had a broken screen. The guy replaced it but the camera looked all pink and…read moreI needed the camera in order to take a class. I reported the issue saying it was the wrong part. He said to bring it back to take a look. I do and when I mention it's the wrong part he gets smart with me pointing to the model number "You see this model number here." then pulls up the one the system says it needs. "It's the same number." Speaking to me as if I'm stupid. I explain that either way the part isn't good if the camera's all pink. He says he'll have it fixed by Wednesday (two days later). I got no call or messages on Wednesday confirming that it was done so I call and he indirectly admitted to forgetting about fixing my computer because he had 'more urgent clients' to tend to first. I go back a couple days after to pick it up. I check the camera was STILL ALL PINK. I call back and was told there was nothing he could do. He then condescendingly offered to return the computer to its original state and give me a refund. I agreed then he added "Yeah, I just don't think our service is good enough for you." In an even more condescending tone acting as if I was pulling his leg for asking him to do his job. Mind you, the guy DIDN'T FIX ANYTHING AT ALL. I'm normally very patient and lenient with people when they work since we're all human but this was ridiculous. Wish I could've avoided the whole situation since my computer ended up the same.
