When it comes to computer repair and sales they are the best. I paid 4, that's right, 4! so called computer repair companies to diagnose and fix my computer when it was getting repetitive stop error screens. Always it would be ok for an hour to a week but it would always do it again. Thank God for Dave because he finally after a year of frustration found the problem. I had a bad motherboard. He was so nice to me and understanding about how frustrated I was after dealing with so many people and paying so much money already. He found me a great motherboard and installed it for me and now it's been 3 years and my computer is still working great!!
