I have power, and I am not aware of any power problems last night.
I cannot get to the start button.
I unplugged the computer and let it set for awhile, then restarted it.
I checked the disc drive bays to make sure they were empty.
When I turn the computer on, the machine displays the following:
(1) "HP invent
Intel VIIV
"
(2) then I get this error message which says: We apologize for inconvenience, but windows did not start successfully etc.
choose last known good configuration to revert to the most recent settings that worked.
-safe mode
-safe mode with networking
-safe mode with command prompt
-last known good configuration
-start Windows normally
etc.
(3) the start screen displays with Microsoft windows logo and bar that has the bar that has blue dashes animating left to right
(4 & 5) there are two other error messages that display too rapidly for me to read.
