We have a HP laptop with Windows 7 that shows the Windows logo on startup and then the screen goes black.  I know the screen works as I can go into safe mode and see desktop.  I did a system restore and still no screen after startup.  Windows gives the trademark chime but no screen although the bios and Windows logo show upon startup

If you see the display in safe mode and not with a normal boot, then something with the normal startup is causing the display to blank. I would guess an invalid screen resolution or maybe a invalid display driver update. Here are a few tips to try ...

Check the Event Viewer while booted in safe mode to see any error messages. There may be some clues there.

You can change the video resolution via resedit. I think for Win 7 the keys are here:
HKCC\System\CurrentControlSet\Control\Video\XResolution & YResolution
You can try setting them to the display's native resolution.

You can also use msconfig (or Task Manager) to manage startup items & services. I'd probably try disabling some startup items first.

Good luck!

when black screen shows then go to task manager (using ctrl +alt +del ) and run the explorer.exe (if alrady running restart the same ). if this doesn't work then create a new profile and check the same

this is usually caused by a wrong video driver
try dowloading and installing the proper one from safe mode

I agree with nobus above windows sometimes download incorrect video driver due to check in and compatibility issues.
