Computer won't boot after Windows Update

[noof]

Computer will not start after a routine Windows update. It does not show the hp logo - just beeps three times with one tone and three times in another

@noof -- does the pattern of "beeps" match anything at: HP and Compaq Desktop PCs - BIOS Beep Codes | HP® Customer Support

Perhaps, my understudy (@Promo_The_US) will interject a response ???

Hi, @noof 

Here is the link to the BIOS interactive code chart for your All-in-One PC.

From what you posted, it sounds like your PC is emitting the 3 Long, 3 Short sequence, and clicking on the interactive chart code for that sequence indicates this...The embedded controller has timed out waiting for BIOS to return from graphics initialization.

Here is the troubleshooting chart for the codes...

Thank you both for the help.

As it happened, the process of removing all of the USB connected devices and un plugging the power allowed for a blue screen to appear on attempted boot asking to restore a default CMOS or something like that.  I have a terrible habit of not thoroughly reading things, and an old age affliction of not remembering such things, but I then got the normal boot and things are back to up and running.

Thanks again!

You're very welcome.

I was totally bummed out. I installed a 2TB NVMe SSD just a little while ago and I have been loving this computer. I don't have a lot of money, so the thought of having to get by on just a laptop made me sick to my stomach.

Your help really MADE my day!!!!  Makes me concerned about using Windows Update on it again.
