Ubuntu freezes

I am trying to figure out the problem with my laptop. It worked great with a duel boot of ubuntu 12.04 and after installing the extreme 120g it freezes a lot. I have to completely shut down my pc wait a few seconds then reboot. It is really annoying. I have been looking for a way to test the drive and can’t seem to find anything online.

Also, I have read the other posts dealing with linux and really don’t feel like getting an ear full of someones opions on Linux. It is more stable than Mico$oft and as a student I need this thing not loosing papers and such. so that said I need help.

If no one can help I will return it and get a different brand…thanks

Do a sudo update. The driver loaded might be an old one.
