Thanks for the fast answer;

The problem I am facing is a more complicated one. I cannot get to the BIOS settings or the windows boot menu.

Basically, once the computer starts the screen is blank, and remains blank (i cannot even see the dell logo). Even if i spam F8, it does not help me.

If i try to boot into Diagnostics (Fn and then Power), i again get no feedback from the screen for ~ 2 minutes the screen starts flashing colors(Same as the BIST LCD test) and series of 3 beeps are heard (repeated 3 times), but as I said the LCD is still not displaying anything so i cannot see the error code.

I have also tried connected an external monitor using the VGA connection, but it gets no signal.
