Do I have a setting wrong?

I have an HP laptop with XP. I used to use an external monitor but it
started saying "no signal" and stopped working. After Office 2007 ran some
diagnostics (probably unrelated) when I rebooted the computer the external
monitor started working and mirrored the laptop screen, apparently working
again. Once the boot-up process started Windows the monitor again said "no
signal" and stopped working again. (All of this with the laptop open).

Any ideas?

Thanks in advance... Bob
