Last week both my hard drives failed and after buying a new one I reinstalled Windows 7 Home Premium. When I tried to reinstall/set up Windows Media Center the set up got to the point where it was scanning my TV signals for channels and was about 1/3 to 1/2 through when the computer killed itself and rebooted. This happened 3 times at about the same place. Why is this happening and how do I get the set up to complete? I had it working just fine before on my old hard drive but I can't now.. I am now using Total Media 3.5 which works but not as well as Media Center so I would really like to get the set up to complete...
