How do you know that the ford of a computer is from the mother board?

According to my understanding if you meant to write fault instead of ford, there are certain explations

• Your computer starts you hear the sounds but no Display (its mostly because of RAM on Mother Board)
• Your computer restarts again and again . (verify the power supply connections)
• Some time the error is on the screen , Like no operating system found , or no boot device available, So you have to make sure that hard disk is installed properly by unplugging and plugging it again . Or may be you have to change the boot sequence
• Blue screen or death screen error.

JUST FOR EXAMPLE TO IDENTIFY THE ISSUE.

The most common fault of all is NO DISPLAY when you switch on the computer, even no beeping sound, it is due to RAM you have unplug the RAM or RAM's if more then one and plug them again to avoid any uncertainty, If the problem persists you just have to take an eraser and gently Rub the lower portion of RAM that you insert in the slot on motherboard, It will remove the dust particles or any material that is stopping the connection, IF the RAM is not okay you gonna Hear a Beep sound.

I am posting a link here to help you OUT because each beep sequence is different in case of every problem on mother board and it refers to solution accordingly.

This will give you an understanding of the fault on motherboards

DO let me know if this is of any help to you thanks.

You can identify the fault of the computer is in the MOTHERBOARD, when:

1. Computer does not reboot/turns on and instead hearing beeping sounds.

2.The computer randomly crashes and shuts down.

3. The system freezes and you can see errors showing.
