Hello and thank you for choosing JUSTANSWER.com
So once the computer shut off, and you try to RESTART it....nothing happens.....are you gettign a black screen with a flashing cursor in the top left of the screen?
Do you get anythign on the screen at all?
Are you famalier with HOW to get to the BIOS? Have you ever had to access the BIOS before?
Is this a LAPTOP or is it a DESKTOP? What is the make and model, so i can pull the manuals.
Do you hear any beeps when you start the computer? Normally the computer will beep if it has found a problem, when it fails the POST test.
Are you able to use a different monitor?
Updating the BIOS is a very scary proposition if you are NOT familier with HOW to do it. As it can render your computer a BRICK, if it is NOT done correctly.
Once i have the manuals, and KNOW of the type of BIOS, and the type of Mobo you have....i can formulate a process for recovery.
Well, it depends on what HAPPENED whether or not I can help.
This computer may have been BRICKED. And there is NO recovery unless you replace the BIOS chip on the mobo.
If what i think happened, we may be able to recover......but give me a few minutes to find and pull the manuals.
