    12.10 very slow and freezes, fan is very loud

    I'm a bit new to Ubuntu. I installed 12.10 64 bit on a custom built desktop, but it runs very slow and often freezes or something like Unity will crash. I'm not sure what the issue is. I tried installing AMD drivers (I'm using an AMD Radeon HD 7850 graphics card) but when I restart the computer afterwards Unity doesn't load. Only the wallpaper and the cursor appear and I can't fix it unless I reinstall Ubuntu.

    Also my CPU fan is very loud. When I boot into Windows, the fan quiets down to a tolerable speed but with Ubuntu it never does and in fact it gets louder after a few minutes.

    This is the output for sudo lshw -C display; lsb_release -a; uname -a:

    What are the specs of the rest of the computer? Does Windows seem much faster compared to ubuntu?

    EDIT: Have you at least confirmed it is the graphics card that's causing the issue? if not I would suggest disconnecting the graphics card and see what ubuntu is like when using the onboard motherboard graphics instead.
