how to rid the computer of the black screen and back to norm

Specs: Windows 10
The computer was turned off normally and the following morning on turning it on, I got a black screen. I can hear the sound of the power only, at times it flashes "no signal" and returns to black screen.

It appears you have a hardware problem. "No Signal" means the monitor isn't receiving a video signal from the tower. Please post the make/model/model number of your computer & anything else that might be helpful. How old is it? Have you made any changes? Did it come with Win10 preinstalled or was it upgraded from a different Windows version?

..... Have you had any recent other problems?

Try this simple thing to see if it works:
Unplug the computer (if laptop remove main battery also). Press and release the power button 4 or 5 times (at least 30 seconds total). Plug in desktop (replace battery laptop) and try again to start it up.

This simply drains the power from the main board and all of the capacitors and may reset things.
It is simple and safe which is why it almost always is worth a try. If it works, you are done, if not then answer the questions and we can suggest a few things to try to narrow things down some.

In general I would try booting to a bootble CD or Flash Drive with a Live Linux or Seatools (hard drive test) to confirm it is hardware related. Typically if you are not getting the boot screen showing up then this would not work either. If it does work then run the short hard drive test in Seatools and even Memtest86 to test the memory. A Live Linux can confirm that there is some hard drive access if you can 'mount' drive and access the files.

You have to be a little bit crazy to keep you from going insane.

If there is no text at all other than the"No signal" message --
that is, the text that normally displays before Windows begins
to load is missing -- then, as riider said, you have a hardware
problem. Either with the video circuitry in the computer or in
the video connection between the computer and the monitor.
Check the video cable first. If you don't find it loose or broken,
then you may need to take the computer to a repair shop for
testing.

If you *do* see normal text on the screen before Windows
begins to load, then either the problem is in Windows, and you
should do the things the others have suggested, or you have a
hardware video problem that only happens after the computer
has been running for a moment -- maybe when it warms up.

My desktop had the problem before.

1. Try to check the monitor cable and power cable at first, make sure it connect to the computer right.

2. Open the computer case and plug out the memory to and plug it again or plug it to another slot.

After that, you will see the monitor has signal.

After that, go to device manger, if your monitor shows as generic pnp monitor, you can fix it by this link: https://windows10skill.com/fix-gene...
