Complete IT Management for Chicago Businesses

  One morning when I went to check my email, I got the Blue Screen of Death with the UNMOUNTABLE_BOOT_VOLUME error. Dan said he could be here by noon and... read more arrived exactly on time. He had to take the computer with him though (the bad news) as the hard drive was fried. But he had a new hard drive installed with the data transferred and everything, and the laptop was running at 100% within 2 days. Compaq is a piece of junk; I'll never buy another one. Dan said they install cheap hard drives and that's the reason why it failed. So, for as bad as the situation was, Dan made it turn out as good as we could have expected. He's a former Marine, so he and my husband traded war stories about what it was like in the "Old Corps", whatever that is.

  I hired Dan to design my website and am completely happy and satisfied with the results. There was always great communication so he was able to create specifics discussed... read more for the site. He goes above and beyond to create an even better site than I originally envisioned. He is very knowledgeable on his skills and was able to explain different aspects of websites that I didn't understand. I will continue to turn to his business for future projects. I highly recommend his company.

  Dan provided great service today! Nice to know we have a trusty IT professional nearby. Thanks!

Dan came to pick up the... read more laptops and scanned BOTH hard drives AND, returned the laptops to Rentex and was able to retrieve any remaining powerpoint files. Although we weren't able to retrieve the correct files, he only charged me $350.00 for BOTH laptops. Which I thought was extremely gracious and helpful in light of the situation. Thanks Dan

  I called Tuesday night around 6:30pm Dan was here Wednesday morning. My computer got the dreaded frozen blue screen. I thought that was the end of it. He was able... read more to fix it and recover and save all the info that I had. Nothing was lost. He ended up updating a 2nd computer, connecting printer and scanner to network.
