restarts after clicking sleep

Check the event log for driver error.  Video and Network card driver issues specifically.

Change the default behavior to NOT REBOOT after a crash.

What blue screen remains?

Ok Muto let me be more detailed.

I have an XPS 410 that I did a full install of Windows 7 Ultimate from Vista Ultimate that was used to upgrade the original windows xp that came w my system.

When I press sleep button it restarts, when it goes into sleep mode when not in use it restarts.

I was having trouble upgrading to WINDOWS 7  and was advised to do a full install.

I gues it has its quirks.

your telling me of possible incompleate install.

Yes I do get the Yellow Bang on the Shut down icon.

Checked Device Manager no Yellow Bangs there.

I hope this may help you help me.

Thanks for al the help
