computer freezes when sitting idol

[Guest]

i recently upgraded my toshiba laptop to vista home premium but i am running
into problems with programs not working correctly. after spending hours on
the phone with microsoft most of the issues are resolved but there is 1 new
issues to resolve.
Does anyone know why my computer freezes when sitting idol ( the
screesaver is set to default settings but does not activate after 10 minutes
) this issue forces me to power down inproperly.
any suggestions on how to fix this problem would be greatly appreciated

I recently installed Vista 64bit from 32 bit and experienced the random
freezing also.
By chance I came across a quick solution top get it out of freeze, but it
does go on and do it at a later time, but this remedy will at least save you
from pressing the reset button to restart your comp.
First click ctrl+alt+del
a screen should come up showing 5 options

LOCK THIS COMPUTER
SWITCH USER
LOG OFF
CHANGE A PASSWORD
START TASK MANAGER

CANCEL
Click on the cancel button, it will reset and the pages will unfreeze.
Please do note though this is for when the pages freeze but you can still
use your mouse
