I just moved into a house (a very old house) and my computer will freeze when trying to boot up windows (at various times during boot up). I have taken it to other places and had it work just fine. One of my room mates runs a similar computer and it runs fine. I have tried plugging in all over the house including where my room mate is plugged in. I can start up my computer in safe mode. This leads me to believe it must be something with the wiring of the house. The electrical in the house does not seam very good (lots of blown breakers) but I still cant figure out why one computer would run while another would not. I might be slow to respond because I don't have a computer!
