Doesn't start as in nothing happens when you hit the power button? Or are you saying the Desktop is black, but it seems like windows started and went through the boot process?
If nothing happens when you hit the power button: Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.
that your unit has some sort ofPSU
fault, or a problem that is shutting down the Power Supply Unit, PSU. The noise is what gives it away. This
happens so that no further damage, and possible fire will occur. You need to take the unit to a reputable service centre/man
and ask for a firm "Quote" for the work to be done. It is that sound that gives it away, this is a typical
switchmode Power Supply problem.
When you turn the computer on do you see or hear any of the following:
-Does the power LED turn on and if so for how long?
-When you turn you power on listen closely for any sounds like hard drives or fans starting up.
-Does anything show on your monitor, if yes what exactly?
-When turned on do you hear any beeping sounds from the computer? If you do listen for the pattern of long and short beeps and let us know what they are.
If you see absolutely nothing you should try testing the socket the computer is plugged into. Fuses blow, power strips die cords develop shorts so unplug the computer and plug in a lamp to verify you?re getting power. If that doesn?t turn up anything let us know the answers to the questions above plus any other observations and we?ll try to help.
