PC won't display anything on the monitor [closed]

Question

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?

Answer 1

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.

Answer 2

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).
