Need computer help, look no further. I can't say enough great things about Dave. I called him over…read morethe holidays to look at my laptop that crashed. He came over the next day, trouble checked everything and was able to retrieve all of my files and programs. He then came back and installed them on a new laptop my employer sent. These files are my bread and butter and I would have been screwed without them. He was a total lifesaver! Not to mention a really great guy with reasonable prices. Trust me, you can't go wrong with Dave!

I hopped…read moreon my boyfriend's 11 year-old uber-slow piece of junk with the goal of finding a local company to help me out, and fast. I got exactly that with Dave's Computer Services. Dave answered my emails and calls in a timely fashion, and worked with me to make an appointment to save my sanity. The whole job took a few hours, and in that time he restored everything back to its original settings, reloaded software I had purchased, and he actually got rid of junky programs I didn't need that were taking up extra hard drive space. He even reloaded a new virus scan program, brought back my preferred web browser, and configured my wireless so I no longer have to plug my laptop into an Ethernet cable. Dave was a very down-to-earth regular guy and was very easy to talk to. I would continue to call him instead of the hyped up franchise company I will not name. :) In fact, he told me he sells used computers as well, and I WILL be calling him to replace that 11 year-old POS inhabiting our home office. Dave quoted me a very reasonable price, so I am very pleased that I can get a deal through him versus spending 4x more elsewhere. I HIGHLY recommend Dave's Computer Services!

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.

Worst experience ever. I took my PC in for them to troubleshoot. After waiting 3 days, I called…read morethem to get an update and the guy on the phone didn't know but said he'll text me back. I didn't hear anything for next 2 days. I finally tried calling back and couldn't get through with anyone but texted them asking for an update. There was no response. 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.

Since I switched to Safehaven none of that has ever happened again. No more blue screen no more lost data no more downtime. The personal care and attention combined with innovative tech savvy is a rare dynamic duo you see much of anymore.
