blank CMD screen pop up

[prInce0712]

hi 

good day! I wanted to check on why there is a blank CMD screen popping up on my laptop after a few seconds of starting it up? I'm worried that it is a virus that would destroy my software. Or is it a malware?

Hi@prInce0712, Welcome to the HP Support Community!

Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance, and find tips!

I see from the post that you are having issues with your HP Stream Notebook is powering on, however, doesn't boot into Windows, Don't worry as I have a few suggestions which should help you resolve your issue.

To provide an accurate solution, I'll need a few more details:

Could you provide me with the exact model number of the notebook? ( Please use this link to help you find this information: http://hp.care/2bygf7l )

Have you performed any steps on your own before posting on the HP Forums?

Have you tried to boot into the Bios with the Hard drive disconnected?

Have you tried to connect an external keyboard and check if that works?

In the meantime, you perform the below steps:

Let's start off by performing a hard reset on the notebook: A power reset (or hard restart) clears all information from the computer's memory without erasing any personal data. Performing a power reset might fix conditions such as Windows not responding, a blank display, software freezing, keyboard stops responding, or other external devices locking up.

Please restart the computer, tap on F10 during the restart and when you get to the BIOS interface, stay there and wait for the amount of time it normally takes to turn off, etc...and reply back with the details of what happened during your time in the BIOS interface. If the screen flickers in the Bios screen as this is outside of windows, this clearly is an indication of a hardware failure.

If the PC stays fine on the Bios, I would suggest you perform a Bios defaults.

Performing Bios Defaults:

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer.

Alternatively, I would suggest here is to remove the hard drive and then try to check if you are able to boot into the Bios. If yes, then it's a possible hardware failure with the hard drive.
