Hi@Reyanshrattu123, Welcome to the HP Support Community!

 

 

 A great place where you can find solutions for your issues with help from the community! I came across your post and wanted to assist you. I understand you are having issues with the computer does not boot into Windows anymore. Don't worry as I have a few suggestions which should help you resolve this issue. 

 

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

When you try to turn it on, do you hear the fan running? Or do you get any beeping noises/blinking lights?

Did this happen after a power surge or power outage?

Have you tried to connect this notebook to an external monitor?

 

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.

 

 

In the meantime, let's start off by performing a Hard reset on the Notebook:

Step 1: Performing a hard reset: 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.

 

Step 2: Connecting an external monitor to test the display

The notebook screen display might remain black when there is a corrupted graphics driver or a problem with the LCD display backlight. To test the display, attach an external monitor and restart the computer. Testing with an external display is helpful if the notebook display is black but you can hear sounds; such as fans, spinning drives, or beep tones that indicate the computer is operating.

 

Step 3: Attempt a Bios Recovery (Skip this step if you have already tried it).

 

Next thing, I would suggest here is to Run a System diagnostics test as well as an extensive test on the Hard drive and Memory from F2 (Please capture the failure ID for further assistance).

 

If all test pass turns off the computer.

As you turn it back on tap the F10 key. This will load BIOS setup utility.
Press F9 to load defaults.
Press F10 to save and exit.

 

For more assistance, please follow all the steps suggested in the support document for - HP Notebook PCs - Troubleshooting Black Screen Displays with No Error Messages During Startup or Boo...
