I recently installed a fresh Ubuntu 12.04 LTS 64-bit version on my PC, First I tried to install it from CD , but it hanged after minutes , then i tried it from a USB thumb drive the same problem ,
then I installed it using WUBI from windows 8 32-bit Pro it installed normally but whenever I boot , It hangs after two minutes, everything stops working but the mouse and the keyboard are working normally.
My PC specs are:
MB : GigaByte G41
CPU : IntelTM Core 2 Duo
HDD : 320 GB WD
GPU : Nvidia GT 630
