Mountail Lion hangs at login

[metramo]

Hi, I built on of the 2011 Tonymac buils Mini Atx Gigabit Motherboard with Core i3 2105 and on board graphics.

Had it for some time and installed a few softwares.
Suddely I can't log in it hangs with the spinning wheel when I have typed my password.
Even restored a backup, loosing the last software installs.

How can I troubleshoot his ???

I changed my display to HDMI 27", but It worked. No other changes made.

Don't want to pay up 500$ for a mac mini when I have this one dual boot with windows 7 and all.

boot -x does not fix he problem, the weel keep spinning

boot -v gives a lot of messages, noteably

running fsck on root volume

I annexed a photo

Don't really know what version of ML

Lion hangs at login - Root Cause

I gave up on this since it seemed from the -v printout that everything was exploding.

I took out my unibeast key and started all over. The Mac installer proposed to reinstall everything on the existing partition, great. So now I'm allmost back to whre I were. Simply No NETWORK: AARRGH.

But the problem, I found in another post. I plugged my USB mous into the front panel. The post suggested moving to another position. It worked!!!!
Really really annoying. I have a working Mac / Hack since a few months and just changing the position of the mouse makes it crash an I lose a lot of time.
Maybe the mac mini is not such a bad idea after all.
