Blank Screen and almost no Sound upon trying to start it up.

[AndyModel4]

I have a HP Pavilion Gaming Laptop 15t-cx0000 CTO. Over 2 years ago, I attempted to download and sign into a game called Crossout. My laptop froze, and I had to force a shut down. Now every time I try to start it up, I'm net with a blank screen and a beeping sound if I'm lucky. I've tried removing and reinstalling almost all of the parts, I've tried holding down the Windows button plus the B or V key along with the power button, etc. Nothing I've seen so far has worked. I'd greatly appreciate help in hopefully being able to get my computer back into functional condition. Feel free to reach out to me for extra details or information. Thank you.

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I understand that your computer not booting up after installing the Crossout game. 

I have a few troubleshooting steps we could try to fix the issue:  
Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (Refer to the removable and sealed battery)
BIOS default:(do not skip any troubleshooting steps even if you feel steps are repeating)

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. 

Hope this helps! Keep me posted for further assistance.
