You had problems with your existing computer, > http://www.geekstogo...th-my-computer/ band issue not resolved, so must make you aware that reusing some of your old parts, there can be no guarantee of a trouble free Build.
99% sure it's the Graphic card - I had with that the last 6 months problem.
Please give the brand/model for all the old parts.
