when i run a program off my cd rom after a while the cpu freezes. and programs that dont run off the cd rom dont freeze. some 1 help me with this problem

When the CD freezes are you still able to use the computer? Or do you need to reboot?

Also: look in your Event viewer: rt. click My Computer then click Manage then Event Viewer.
Or: Administrative Tools/Event Viewer or Start/Run/ eventvwr
Open the system as well as the application tabs & look for X errors. Click error line for details.
Post back the source & event id especially of errors that seem to coincide with a freeze.

the whole computer freezes up and i have to reboot
