Tips for a great answer:
to get to Task Manager. Hold the Ctrl key, plus Hold the Alt Key then hit
the Del key while holding them.
Once the task manager opens Clcik the Processes tab then click the Image Name
Column heading on the left to get them in alphabetical order. Scroll down
and look for explorer.exe. If you see it click it to highlight it then
click End Process.
Next, click the FILE tab at the very top left of the window and select New Task (RUN). When the Create New Task window opens type explorer.exe and press ok. Your start menu, task bar and desktop icons will start appearing and populating. if not that means a virus has hidden your files and folders.
If it is not resolved try the steps below:
Shine a flashlight on the dark screen to see if you barely
see 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 be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without 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 correct key for displaying on the monitor (F1 thru F12). The correct key will normally 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 light and nothing shows on the external monitor, then most likely your video card is bad.
