My computer would not start up. I turned it on and within one or two minutes it would turn off. Robert at Digital said it was over heating. I had my computer repaired at Digital Tronics. he got it working again in less than a week not only was the problem fixed, but he also cleaned out all of the leftover files that made it run slow, from many uninstalled programs, he updated my browser, and installed for me a free firewall and antivirus program. I would recommend this guy to work on your computer. He's nice, smart, and friendly. The work is reasonably priced too. I will be going back here in the future.
