  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. He was very polite and professional. He really saved our business and took away the major stress we experienced when the computer went down. When I called he answered right away. So happy with the job he did. My computer works better then ever. He saved us a lot of money, we thought for sure we would need a new computer. To install all of our work applications would have been a lengthy and stressful process. Thanks to Dan we did not have to do any of that. I would recommend him to everyone and if we have issues in the future we will be calling him for sure with no hesitation. Save yourself the stress and call him. He will help you. Thank you again Dan, we appreciate all your help.

  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.

  Called Dan at Dantech in a pinch when a client did NOT save their content on a rental laptop as they thought they had. 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
