Help. My computer keeps shutting down anytime I try to view photos. It doesn't matter if I am on the internet at a Kodak site or on Picasa, my computer just shuts off. I have run a scan with norton and have no viruses. Please help! Thanks!

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 this issue.
