this really depends on what kind of (old/new) hardware you have.

There may be some hint in /var/log/syslog.

Please paste here more information (from "lspci" and/or hwinfo) as suggested above.

You can also try looking at https://help.ubuntu.com/community/ReportingBugs#Tips_and_tricks

and/or possibly finding already existing bug here: https://bugs.launchpad.net/ubuntu
