My mouse driver constantly freezes up in 11.10 and I can't seem to fix it. Once it freezes I have to restart... which means tons of restarts every day. I can barely get any work done.
Also as of the other day after installing some updates in the update manager my computer has decided to shut itself down randomly. It's already happened 7 or 8 times today and about the same yesterday. I can't get it to stop.
