hi help needed.
my vaio fz laptop lights up i hear the hdd spinning and the fan but i wont boot the screen stays black there are no beeps. please can anyone help?.

Try and connect your laptop with an external monitor to check if your screen is the problem. if u connect it like that and its still the same, then try it with another RAM, CMOS and your CPU (processor). if its still the same, your mother board might have gotten an open circuit somewhere on the board. THEN IT NEEDS REPLACEMENT.

Have you tried a repair?
What os are you using and do you have a disc?
