I took a pc to TC Computers, They told me my xps 400 motherboard was bad and was going to cost over 200 dolalrs to fix. I then got a second opinion at One Stop Computer Shop, and they told me a was a very simple problem with a loose memory chip. They charged me $19 dollars to cover the estimate fee, and that was it. TC Max is supposed to be pros, but the One Stop truley is the One Stop Computer Shop.
