PC boots up but monitor shows 'no signal' and keyboard not working.

My W10 PC boots up, fan spins, HDD spins but there is no output to monitor, which shows 'no signal' and the keyboard does not light up. I have tried all the suggested diagnostics such as unplug power, take out the CMOS battery, re-seat the RAM, clean RAM etc but nothing. It did come back on a few weeks ago for a few days then reverted to display showing 'no signal'. Any suggestions how to get this PC to display and work again are welcome.

Many posts i have read suggest entering BIOS etc or settings - i cannot do this as no display!

Please suggest fixes for my situation as above.

Thanks

    Thanks for your answer, however i have checked all cables and connections and these are fine (work with other pc). Re step 2 - i cannot boot to safe mode as there is no monitor signal so i cannot see anything except a black screen.

    how can i boot my PC to safe mode if i cannot see anything?

    I can't change the signal resolution either as no monitor!!

    'No signal' means that your monitor is not receiving a video signal that it can display. This is usually due to one of the following causes:

    1- The cable going from your computer to your monitor is loose. Power off the monitor, re-attach the cable at both end, power on your monitor. (This step is N/A if you have a laptop or an AIO.)

    2- The signal your graphics card is sending to your monitor can't be displayed by your monitor. Boot the computer to Safe Mode, choose a low resolution signal, restart your computer normally, switch to the 'Recommended' resolution for your monitor.

    To change the signal resolution: Start > Settings > System > Display > Display resolution.

    Your problem is not related to your BIOS, unless you made changes to the BIOS yourself.

    Your fault could be anywhere along this path:

    Graphics Hardware.

    Monitor > Cable > Port on Computer > which is either connected to a Graphics Card in a slot on the Motherboard or to Onboard Graphics Hardware which is part of the Motherboard.

    Unfortunately there is no way except to swap and test Graphics Card, etc.
