I'm also having a similar complete freeze, no mouse movement. Fresh install 12.04 32bit is freezing every so often. Was watching a video earlier, noticed the curser was no longer moving for me then the video started shuddering. Was typing an email a few minutes ago when it froze again. I think this has happened like 5 or 6 times now. I have to hold the power button to shut it down, then when it starts again it stops at the colored screen but has a black section across it with colored lines around the edges of the black, press the reset button and it will boot to the grub boot menu. From there it starts ok but long boot time.
