There are two kinds of IT people, the ones who leave you more confused than when you started, and…read morethe ones who quietly solve the problem and get you back to running your business. Working with Matt was exactly that. He was prompt, professional, and refreshingly easy to work with. No unnecessary jargon, no drama, just honest expertise and a genuine commitment to getting the job done right. As a small business owner, having someone reliable to call when technology gets in the way is invaluable. If you're looking for an IT professional who knows his craft, communicates well, and delivers on his promises, I highly recommend him. Good people are hard to find. Great IT people are even harder.

I can't say enough great things about Matt. He absolutely saved me this week…read more My Lenovo laptop completely failed to boot after a graphics driver cleanup utility corrupted the Windows boot configuration and recovery environment. The system was stuck in a recovery loop, BitLocker was triggered, and Windows wouldn't load or even reliably enter repair mode. Multiple shops I called said it would take several days just to diagnose the issue. Matt turned it around in essentially one day. He was able to manually access the system, unlock BitLocker, repair the corrupted boot configuration, rebuild the necessary Windows files, and get the machine fully operational again -- without wiping my data. That was critical, as I had local files that weren't backed up to the cloud. Beyond the technical expertise, what impressed me most was: * Clear communication * Fast turnaround * Extremely reasonable pricing * No upselling, no unnecessary "reinstall everything" approach He diagnosed the real issue quickly and fixed it correctly the first time. If you're an independent contractor who depends on your machine daily, or you run a small to mid-sized business and need reliable, competent IT support, Matt is exactly who you want on your side. Look no further. Highly, highly recommend.

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 then go in and the guy was extremely rude and pointed at my computer which was on display at the front. It looked like it wasn't even looked at. I took it back and the guy was just very rude and awful. Very unprofessional people who don't seem to know anything about computers.

By halfway through the second day, I called them for an update. They said they were working on it. Three hours later, I called again, and they gave me the same answer. This time, they mentioned they were preparing a quote for the repair because the motherboard was damaged and it would cost $750. They explained that they would need to send it out to a specialty shop. However, they assured me they could back up my data, which I requested, and they did manage to do that. When I went to pick up the laptop, I noticed a plastic bag taped to it containing some hardware. I asked what it was, and they informed me it was the SSD (the new type of hard drive) from which they had retrieved my data. They did not reinstall it in the laptop, which I found puzzling, as I intended to take it to a locally owned computer repair shop for a second opinion. Having never opened a computer before, I thought, "What do I have to lose?" So I opened it up and found the connection point to reinstall the SSD. I had to go and buy a small screw to secure it, which they did not return with the SSD. To my surprise, when I turned on the laptop, it worked perfectly! I am not sure what they were doing for three days, other than backing up my data. Honestly, the store name should be changed to "We Break It, You Pay Us, and You Fix It."

We were pointed to this location through our phone insurance company, asurion, who provided us a list of locations that fix cracked phone screens for $29. Thankfully we only had a cracked phone screen situation. Of the three locations suggested, we chose the Vernon Hills location based on the great reviews. To make the appointment, we filed a claim and prepaid ahead of time. We were given a specific time to come in, and when we dropped off the phone we filled out a questionnaire to verify the diagnosis. We were told to come back in 1.5 hours. They called us at exactly 1.5 hours to come back and pick up our phone. When we picked up the phone, it was like nothing ever happened. The phone looks brand new, and it is brand new because my son just got the replacement after destroying his other phone two months ago! Take note, they used OEM parts and our phone was replaced with an original Apple screen. The phone repair is under full warranty. The business was clean and orderly, and the process was super duper easy. Nice waiting room with mints and a Keurig coffee machine. The employees were friendly and courteous and did everything they were supposed to do. To this day the phone is working like a champ!
