I made the mistake of trying to upgrade my computer myself with a disc provided by the manufacturer and I basically killed it. Not matter what I tried as far as recovery, etc., nothing was working. I called a couple places to get estimates on repair but their quotes included minimums and not even a free diagnostic. Before I threw in the towel and invested in a new computer I checked Yelp and Tech Mail came up. They offer a free diagnostic so I too it Saturday afternoon and spoke with Mitch. He quickly determined the problem and solution and quoted a more than reasonable price. He called to let me know it was ready the next day. It's like I have a new computer. Mitch installed my printer, scanner and Netgear so once home I plugged it in and was ready to go.
Tech Mail also sells computers, ink and refills, offers internet at $3 for 30 minutes, notary, mailbox rentals and other services.
ETA: I received a phone call a few days after I picked up my computer to verify everything was working correctly and I was happy with the outcome.
