Display Problem

I've got this problem with my HP PC displaying WIN 98:

--It starts up good, shows the Windows 98 screen (full screen) twice,
--It then waits a moment & the Desktop comes up but it's only about 3" high
(got a 15" monitor hooked to it) right in center of screen but very hard to
read it. I've tried all the monitor adjusts, no help,
--I can restart in Safe Mode and get a full screen Desktop with all the
icons,
--Of course in Safe Mode, it won't let me make adjustments through the
Control Panel such as adding new devices, thought maybe I'd need to add the
monitor though it's an HP Pavilion monitor.

Any suggestions? I've got my Win 98 SE CD from PC that died, wonder if that
would help?

Thanks for any suggestions,
