Windows 10: Updated today 3-24-20, now computer won't boot up

I updated when Windows prompted me to, said I was due for update. So I did and restarted my computer.


Nothing. If I push the power button I get a blank screen that says "Check HDMI-IN cable". I do not have HDMI connected to it.


This is a newer purchased 12-2019 HP Pavilion All-in-One 24-xa0024.


Sending this from another HP, laptop. It also wants me to update......that wont be happening.


Any help appreciated. I do have this laptop that also runs Win 10 so maybe a bootable flash drive? I need some way to access the computer. I tried unplugging it after maybe 15 minutes of a blank screen and nothing.

computer won't boot but has power

Kursah, that 6 steps are granted it always boots at the 6th step (sometimes at the 4th) and I have to remove the ethernet cable every time otherwise I'll have to do countless steps, that's a fact. I do not have Wake On Lan set.

 

Laptop went black and won;t reboot

Hi Andree,

Hardware and software conflict is one of the possible reasons why you're experiencing black screen. Sometimes, it is also because of hardware failure. To get this issue fixed, we suggest that you
boot into Safe Mode by following these steps:

• Turn off your computer 3 times while booting. Windows should automatically boot to the Recovery Environment after 3 unsuccessful attempts in a row.
  
• Once you are within the Recovery Environment, select Troubleshoot, and then
  Advanced options, then Startup Settings, and
  Restart. When it restarts, you should see a number of options. Press 5 or F5 for
  Safe Mode with Networking.

Once your computer is in Safe Mode, please follow the workaround provided on this
link. Simply select the similar case that you're experiencing to show the troubleshooting steps.

Let us know how it works.

I would still say try a different PSU... here is a solid budget power supply:

EVGA 430 W1, 80+ WHITE 430W, 3 Year Warranty, Power Supply 100-W1-0430-KR, Black:Amazon:Computers & Accessories

Interesting with the NIC connection...not sure what to make of that. What are your system specs? Make/Model of all your components? Check my system spec's for an example.

Honestly I would do process of elimination to another step...and that step would be the PSU. If nothing changes after that..I would try to force flash the CMOS if possible..to ensure no corruptions lie within that.

I would also try as I suggested above and try to boot with minimal hardware... you need an STDIN...Keyboard, STDOUT...VGA, CPU, stick of RAM and power to be able to perform POST on the mainboard. So starting with that would be a great place to go next.

If nothing changes..depending on what you're running a different CPU might be the next step... by the time you're done...you might have built a different PC. But you'll also have more experience in PC diagnostics which is a huge plus for odd issues like these...wish it was in front of me so I could examine and diagnose.
