I just formatted the hard drive, installed Vista and updated everything. It use to hang on startup before so I thought the formatting would help. I have all current drivers installed but sometimes I just see the microsoft screen with the little green scroll bar, and then nothing. I think it is a video driver issue. I thought it may be software but I am beginning to think it is hardware...like I said...all drivers are up to date. I'm stumped I just put in more memory from 480mb to 2gb..it finds 1.97gb...close enough...lol
