12.10

Error occurs during startup of Ubuntu Installation. Sometimes I'll get to the Welcome screen just like this, the screen will just glitch out, or will simply freeze during the loading icon.

nvidia GTS 250
Intel Core i7 920
9 GB Memory

I was able to install 12.04.1, but after performing upgrade to 12.10 it get the same problem on startup; glitches in graphics, missing content etc. Also noticed after the upgrade, I'm no longer able to connect to internet; neither ethernet or wifi.
