System freeze upon startup, can move mouse around, nothing else. (dualboot 12.04)

http://askubuntu.com – I just equipped my new laptop with Ubuntu, and for some reason it keeps freezing very shortly after booting the system! I can move the mouse around, but it doesn't change the pointer from the mode it was when it froze, for example if I was about to click a type-box before freeze, it stays in the text-marker thingy, no matter where I move it. Never had this problem on my old laptop, (used Ubuntu since 9.04) but now I'm forced to work from Windows! Not sure if this is because of my new Chipset, or some problem with dual-booting in Ubuntu? (My other OS is Windows 7 should it matter). It seem (HowTos)
