10.04 freeze

Hello

Description: Ubuntu 10.04.1 LTS
Release: 10.04

I noticed this problem previously on 9.04 distro

At least once a day (2 times in less than 10 minutes right now) , when using chrome, firefox (both or not), the keyboard doesn't respond, the mouse move, but only the right button seems working, no action can be performed on the screen (the windows or the Ubuntu menu)

Only solution : the 'power off' button of my Dell Inspiron 1501 ...

Never had this problem before 9.04 version

Hope it will help
