The safe mode does not load any of the memory or video managers. Restart, hit F8, and do a logged boot or similar. What you want to do is watch it boot every driver, etc...when it hangs on one, you'll know what the problem is. 9 times out of 10 its memory or video problem. Did you recently install a program or device, PCMCIA card, USB, etc?
