Yea, lots of info is needed. Lot of people around here seem to have computer knowledge so I'm sure you'll be able to get some help.
I for example went to college for computer networking, and have been self taught for about 9 years before that so... I've got a little comp. background. Just let us know what you've got going on...
Again like others said, we need to know Mac or PC, What operating system you're using(IE windows xp home or pro/vista, 32 or 64 bit) stuff like that, and any error messages you may have gotten.
