Screen goes blue after many attempts at incorrect sign in

[TwinklePink]

A friend of mine tried to sign in to computer with WRONG password. After many attempts at this, the computer advised her to turn it off. Instead of holding the button in briefly before letting go, (said friend did a quick release on the button, turning it off) Now when you attempt to turn on the computer, all we get is a blue screen, and nothing else. Is there anything short of taking the computer in, that we can do to move past the blue screen, into a screen that allows us to sign in??? PLEASE HELP!! WE ARE LOST WITHOUT OUR COMPUTER!
Many, Many Thanks!

You can try a hard reset.
IF it's a laptop then....
Disconnect it from any AC power source, flip it over and remove the battery, flip it back over and press and hold the power button for a count of 30.
Replace the battery, plug it back into AC power and fire it up.

IF it's a desktop, you may have to remove the mother board battery, but..... try it without it first.
Just disconnect the AC Power and press and hold the power button for a count of 30.
Plug it back in and see if you can turn it back on.

Hi Trouble, ok I unplugged the computer, and held button for 30 seconds. I turned it back on, and it had the Windows symbol in the middle of the screen and beneath that it said "preparing for automatic repair" then the that goes away, and leaves us with a dark blue screen. Any reccomendations now?
P. S Thank you so much for your time

Any reccomendations now?

Yes give it some time.
Does it have a hard disk light on it, do you see it flashing indicating disk activity and something actually going on?

 

[TwinklePink]

No, there are no lights flashing. I should also tell you that this is a Dell desktop computer with an LG monitor, & Windows 10. I repeat there is no flashing light on either the computer or monitor....

Most Dell Desktops will have a disk activity light on the face of the computer, usually about midway down the front.
Sometimes they are amber, sometimes red and sometimes even blue and they are often very faint and subtle unless the activity is very intense.
You may need to boot from the installation media and avail yourself of some of the advanced troubleshooting options.

https://www.microsoft.com/en-us/software-download/techbench
Choose Windows 10, the first item in the first drop down (not single language at the bottom)
Next choose your language and your bit version (32 or 64 bit to match your system architecture or in the case of an upgrade, to match your currently installed version of Windows).
That will provide an ISO that will upgrade, repair (or clean install) either or both Windows 10 Pro and Home.
Once you have downloaded the ISO you can use ImgBurn to burn it to a DVD http://imgburn.com/index.php?act=download
OR
Rufus to burn it to a USB ThumbDrive http://rufus.akeo.ie/
When you've managed to boot from the installation media you need to click the Repair Your PC link on the second page after the Choose a Language and Keyboard layout page.
That should get you to the Advanced Troubleshooting options, where you can try
Startup REpair
System Restore
OR
Maybe Startup settings to get you to a safe mode boot.

Should look something like this
