I push the start button and the power light on the front blinks but the computer won't start. The power light on the back is on, indicating there is power to the computer. Once I hit the power on button on the front of the computer the power light blinks but then if I push the power button again the power light doesn't blink. I have to disconnect the power cord then reconnect it and the process starts all over again.

I've look online, everywhere I could think, but to no avail.

Can anyone give me any advice as to what is going on and perhaps what to do to fix it?

last monday i had a problem with windows updates and had to contact microsoft support for help when i was in live chat.. she asked for my permission to remotely access my computer (OK'ed by me) and she tried everything after a few reboots just like i did with no luck.. but then she wanted to do this n that and i said ok as long as she knows what she’s doing.. then the last one she said it needed to reboot in order to change my local account and we just stayed on and i said ok.. after rebooted, the blue dialog popped up on the screen showing ‘Boot Device Not Found’ and i got !#^&@@ because it’s happened twice.. i knew it wouldnt do anything but i tried anyway.. nothing’s succeed even been trying for almost a week and had to stop since yesterday.. contacted hp for help with no luck but they suggested it needs to be dropped off at the store to have an expert to do so.. (will do that later unless i get it fixed)..

(something popped up on my mind there’s another computer sitting in the closet.. i went and took everything out and set up with my same account and yay.. a coupla hours later for no reason it doesnt work anymore.. very frustrating.. put them all back in the closet and will need a tower to be dropped off at the store later or i'll re-try it myself later..)

so, on my computer on the desk i do not have 'Continue' and 'Use a device' but only 'Troubleshoot' and Turn off your PC'.. and i clicked 'Troubleshoot' and do not see 'Reset this PC' but 'Advanced options' that i clicked on that has all there but nothing worked..

so then, i installed windows 10 media installation on my flash drive from this computer (kids') and re-tried with my computer.. lotsa problems but one thing on the local account screen shows 'sandi' that microsoft support created the last time to change from Administrator.. i typed my password that's incorrect then tried my 2 old ones not succeed and tried 'reset password' that i needed to have a reset password cd i created but i didnt.. how do i get a system restore not a hp recovery (i do not want to lose anything such as my personal files/pictures/videos, etc, etc..)

the problem on my desktop shows 'boot device not found', although, i've tried so many options that are not succeed.. only i did was test that showed system/memory diagnostics was passed but still the boot device issue.. is there any way to repair my computer without losing my pictures/videos/documents, etc, etc?

the system i'm unable doing anything with options below

System Restore - To use System Restore, you must specific which Windows installation to restore

Restore this computer select an operating system and then System Restore

i do not see "Reset this PC" nor "Continue" on my computer

Go back to the previous version - ......won't be able to take you back to the previous Windows. Try resetting your PC instead (Trouble> Reset this PC)

System Image Recovery - Re-image your computer that states 'cannot find a system image on this computer

Start Repair - Startup Repair couldn't repair your PC

Command Prompt - Administrator: X:\windows\SYSTEM32\cmd.exe

Microsoft Windows [Version 10.0.17134.1]

Not enough memory resources are available to process this command.

X:\Sources>_

i did this and nothing's changed or succeed

UEFI Firmware Settings

Restart to change UEFI firmware setting [restart] and select System Recover

right now it reads on the screen

Intel (R) Boot Agent GE v1.3.76

Copyright (C) 1997-2011, Intel Corporation

Intel (R) Boot Agent PXE Base Code (PXE-2.1 built 090)

DHCP............................................................ (since no longer shows 'sandi' on the local account screen)

and another problem

without a flash drive installed

ERROR: No boot disk has been detected or the disk has failed.

I hope an expert can help resolve this huge problem..
