Hello a friend of mine has the Novatech Gamma PC with Windows 7 on it. There is a build number 7601 in lower right of screen and if he plays a game or do anything it asks for admin rights. The screen is blank. How do you fix this error.I checked the ram with memory tester. It's okay. Also how do you remove the front cover on Novatech Gamma PC, and put a fan there. Also Microsoft Office does not work with it properly. What is going on help!
