hp pavilion computer starts showing the hp logo and the computer tries to start but
an error message comes up saying "trying to start" but screen goes blank. Worked
fine earlier today. The screen is lit up but with nothing on it. HP tech said he could
tell me what to do to fix this but it would be $200.
