I have a problem with my PC. When I press the button to turn it on, it's working but it won't show anything on the monitor!

I think there might a problem with the graphic card or something. What are your suggestions?

If everything used to work, then a graphics card failure is rather low on the list of things that can can go wrong. Things to check first (and maybe double check):

  1. Monitor's AC cord is plugged in on both ends.
  2. Video cable (VGA, DVI or HDMI?) is plugged in on both ends.
  3. Substitute a different monitor.
  4. Substitute a different video cable.

There are many possible reasons:

  • The monitor cables are not properly connected.
  • The monitor is not plugged in or turned on.
  • If there is more than one GPU (such as onboard and discrete GPUs), the monitor is connected to the wrong GPU.
  • The video cables or connectors, on the monitor or graphics card, are damaged.
  • The graphics card is not properly seated in its expansion slot.
  • There is not enough power from the power supply reaching the graphics card, or the power supply is failing.
  • The monitor is broken.
  • The graphics card is broken (the BIOS may detect this problem and give a beep code).

The BIOS cannot detect all instances where the graphics card could be broken. – Ignacio Vazquez-Abrams Jun 16 '11 at 0:36
