Embedded hardware not working, and boot hangs on "Configuring Network Interface"

I recently wrote a "alias net-something-10 off" to "/etc/modprobe.conf," though I do not know if that's the problem, as I don't remember if I rebooted after that. I think I also ran some "xnetworkconfigeration" or something, and I do not believe I rebooted afterwards, before the glitch.

The graphics card, which is a NVidia Geforge 9600M GS 1GB, is not working either. I have the drivers installed.

All of this was working eariler, before I did something wrong/something glitched and screwed the computer up.

I'm posting this in newbie questions too, as I have no clue as to where this belongs.

This isn't an embedded issue.

You're graphics card alone has more power/memory than most of my development boards put together. =;-)
