I'm having a bit of trouble installing Windows 7. Whenever I get to the "Expanding Windows files" portion of the install, my PC will just shut down. The shut down isn't at a consistent place either, which tells me it isn't the disc (which I burnt a W7 iso on to). It'll shut down at about any percentage through this portion of the install. It's shut down at 6%, 55%, 95%, so not at any one point.
My PC isn't new by any means but it should be able to run 7.
