I don't recall if you said you could get it to start at all but if it starts for even a brief period of time run this program...
It's free and probably the best program I have run on my comp. It's running so damn fast now. It rules.
If your comp doesn't get on the internet then download this program to another computer and copy the first file that downloads to a disc (before installing it on the other comp.) Maybe you can do this at work or Kinko's or something.
Good luck. And for anybody else, this program is highly recommended. Gotta witness this great new free program!
