black screen with dash

[lolgtg9]

so the problem with my HP laptop started with an electricity cut out where there was no battery and when the electricity was back the laptop didn't power on so it was a problem with something in the power after i got it fixed the laptop started acting weird where the "black screen with a blinking underscore" started to appear and per vented booting unless i press any button several times and when i got it to boot on start up it started to open multiple windows of whatever my default browser is and also opening many new tabs. somehow this problem vanished(except for the black screen with a blinking underscore) after desambeling the laptop for cleaning the fan.



- now the main problem is when i formatted the c drive which had the windows 7 to use only windows 10 on my d drive it become unbootable with black screen with endless blinking underscore, even when i tried to boot from a CD it sent me back to this black screen, what should i do?

Try these...


Option 1 ...

1. First, while the computer is off, connect an external monitor.
2. Next turn on the computer and allow it to fully load.
3. Once loaded, press the "Windows Key" + "P" to open the "Easy Display Switcher".
4. In here select "Computer only".
5. Now shut down the computer and disconnect the external monitor.
5. Disconnect the external monitor
6. And finally restart the computer.


Option 2 ...

Make sure you wait until the computer would be fully loaded before trying this, and not try it right away like you would to say get into BIOS. This needs you to actually be where you would be when Windows Explorer loads.

1. Press "Shift" repeatedly until the "sticky keys" window shows up.

2. Now click the the link there that will lead to the "Ease of Access Center".

3. Next click "Cancel" on the the bottom right corner of the "Set Up Sticky Keys" window.

4. From here you want to click "Control Panel" on the upper left corner (it should be right beside the "Make Your Computer Easier to Use" title.

5. Locate the "Computer Settings" menu and then choose the "Recovery" icon (make sure that your view of this is by either large or small icons for easier access).

6. Now click and open "System Restore".

7. Here you want to click next on the bottom right corner (a few times) until the button "Finish" shows up and then click it. (Just follow everything prompt that the window says which will lead you to recovering your previous system, in a certain time.

8. The computer will now do the work it needs to and then reboot.


If that doesn't work, you can try the following...

You can also try doing the Ctrl+Alt+Delete and see if you can get "Task Manager" to show.


If the "Task Manager" windows shows, then choose "New Task" and then type in EXPLORER. If the desktop shows up then you need to go into "Start", "Programs", then "Accessories" and finally "Command Prompt". (Or you can do a search for CMD.)

Make sure you load the "Command Prompt" with Administrator access. Then when it loads type in....

SFC /SCANNOW

It will do a file check.
