Ubuntu :: USB Wifi Makes Desktop Crash But Netbook Works Fine?

Ok, i bought this usb wifi adapter: [URL]

used these drivers(dident work at all without it, no lights even): [URL]

and i first tryed it out on my netbook (aao, intel atom ubuntu 10.04 32bit), i ran make, then make install, done! i pugged it in and im happly using a 300mbps wifi network.

then i try it on my desktop (custom, AMD phenom x4, ubuntu 10.04 64bit), i install, no errors, then when i plug in the wifi usb, it lights up, then stops, the mouse also stops working(bouth keyboard and mouse is usb) but the kb still works. aftor restarting keeping it pluged in, ubuntu never finishes the splash screen, just stops their, i try again without the wifi and it works, i keeped trying and now the whole comp frezes, even the kb, and i see the system monetor is also frozen, what do i do?

one last thing, it works on bouth my netbook and desktop under windows 7, only on my desktop it wont work on ubuntu.
