Windows 10: PC has power; attempts to boot; no signal to monitor or wired mouse

HP Pavilion PC. Is older, but was working fine yesterday. Went to shut down; it paused and asked “shut down or advanced options?” and I chose the former. Now, won’t boot up. Press start button, fans turn on and CPU I assume starts whirling, but no signal to monitor or wired mouse. Have checked cables, unplugged/ replugged power, replaced CMOS battery. No improvement. I do not think there is separate from mother board graphics card. I did reseat the RAM card. Any guidance will be appreciated.

Pc starting but no power/signal to keyboard, mouse or monitor

Hi,

So I've had my gaming pc for a while now.

It runs fine but recently did a factory reset and followed this guide afterwards;ttps://www.youtube.com/watch?v=pJTCwSX9Ym8&list=WL&index=5&t=0s it was fine and so I left it on just downloading a game a few days later, nothing unusual. I came back to it
on but no signal on monitor and no power to keyboard and mouse. I've tried going back to a restore point before following the youtube video and still not working so I don't think that's the problem.

Operating System - Windows 10

Device - Zoostorm Computer

Specs -

ProcessorIntel(R) Core(TM) i7-4790 CPU @ 3.60GHz

Video CardNVIDIA GeForce GTX 750 Ti

Video Card #2NVIDIA GeForce GTX 970

RAM16 GB

Operating SystemWindows 10

But it had been working fine, the only thing I could think of is if I had a pre-existing virus or something that was causing this but surely that would've done this sooner. Anyway, right now when I turn my pc off it does the above again, power to the pc
but no keyboard or mouse power and no signal to keyboard. I have figured out that if I take one stick of RAM out (I have two 8gb RAM) and start it up on just one it all boots up and powers everything fine. I then it off, insert the other stick of RAM and start
it up again and it works. But then I power it off at the end of the day and have to repeat those steps again the next morning. This has been happening for a week-ish now and it's just getting time consuming and annoying to do everyday.

Any help or advice would be appreciated.

Thanks, Lewis.

 

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

'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.

 

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
