No signal to PC screen

No signal to PC screen

No Signal Displayed on the Monitor.

No signal message displayed on the monitor comes from the BIOS of your monitor. This means your computer is not connected to the computer nor doesn’t receiving any signal coming from the video adapter.

There so many reason why a monitor displays the “No signal” message on the screen. So you need to consider the following items for you to fix your computer.

Signal cable and its connection from video card to the monitor. Most of the time we forgot to check the signal cable on the back of the monitor when we receiving errors. Check it’s the connection on the back of the monitor. Be sure that the cable was plug properly. The cable can’t be plug-in in reverse order because of its “D” shape so there is a not possibility that you plug your signal cable in reverse order. Just check them unplug the cable and plug it again just to make sure the cable was plug-in properly. Next is checking the cable at the back of the CPU (Central Processing Unit) if it is connected properly. Just do the same to make sure that the signal cable was plug-in. If problem still exists, move on the other fixing option.

Video Adapter and its connection to the Motherboard. If your video card adapter is built-in, just move on the other fixing option. Let’s say it is not built-in, unplug your video card, grab a pencil with eraser or just an eraser, and erase the dirt on the pins of the video card until it looks like shining gold. Plug your video card on the slot from where you extract the video card before.  WARNING: be sure you unplug your power chord from the power outlet to avoid electric shock when you are working inside your CPU. Turn on your computer once again to check the changes. If nothing was fixed move on to another option.

Memory and its connection to the Motherboard. The same with what you did on the Video Card adapter, pull out your memory modules, grab an eraser and then erase the dirt on the memory pins so that the connector on the memory slot will be properly connected or intact. Put it back then turn-on your computer to check if it working now. If nothing happened, move on the options.

NOTE: When there is a problem in your video card or in memory, you will hear a sequence of beeps and this is what we called the beep error codes. For more information about this audio beep error codes, refer to your motherboard manufacturer manual.

Motherboard of the computer and hardware. Unplug all peripherals connected into your motherboard, power-on your computer and wait for the long beep codes. If don’t hear anything, there is a possibility that your motherboard is busted or the processor. If you hear a sound, put your memory and video card on their slots. If you still hear a sequence of beep codes. Try to replace the memory, then next is the video card if error persists. If it is working already, plug all other peripherals one by one after checking the output on the screen. If you plug the device then screen displays “No Display” diagnose or replace that peripheral. If still cant be fixed, replace your motherboard.

Power source. There are some instances that our power source cannot supply the necessary power needed for the CPU. If your CPU does not properly power, the computer could not work.

Your monitor is good because the monitor is able to display message.
