Re: Dell Inspiron 546, OS Windows 7 upgraded from Vista.. A couple of days ago, I received my new keyboard (multi-media). I was messing around with it getting used to the keys and I hit the key with the half-moon on it and then all my trouble started. I ended up with a screen that says; Windows Resume Loader and that its it. Keyboard doesn't work, Mouse (also new) doesn't work. Nothing Works! I don't know if it's because of the new board or is it a coincidence and something blew. I have tried just about every disk that I have and tapping keys while re-booting doesn't get me anything either. I am s-t-u-c-k.
