After you power-on the computer, repeatedly press the 'F8' key, until you get a "system repair" menu.

One option should be to use "System Restore" to time-warp your computer to an earlier date, i.e., before the problem occurred.

Thank you.  Hp support by phone and email  was very helpful.   Final resolution. .  You must reinstall the factory 

Software pkg stored on the  HD.     E-MAIL, PRINT DRIVERS, AND VIRUS SOFTWARE MUST BE COMPLETED

AFTER THE ORIGINAL  SOFTWARE HAS BEEN INSTALLED .   THIS PROCESS REQUIRES ABOUT ONE HOUR .

MY HP  CMPTR IS NOW FULLY OPERATIONAL.  THANKS AGAIN FOR YOUR ASSISTANCE ..  DEL  SPOKANE..

Compare to: you must trade-in your automobile when the gas-tank gets empty.

Yes, that works, but the "less-drastic" remedy is to refuel.

Similarly, there probably was some other "less-drastic" method to repair your copy of Windows.

Did you manage to make a backup of your documents/pictures/E-mail before reinstalling Windows?

Or, did your files "survive" the re-install of Windows?
