Welcome to the HP Support Community.

Thank you for posting your query.

I understand that you are using an HP Laptop 15-ef1072wm and that the system initially booted normally, but later encountered a BSOD with red lines on the screen. After restarting, the Caps Lock LED blinked 5 times fast followed by 3 times slow, which may indicate a hardware-related issue. I would request you to please follow the steps:

A power reset clears temporary information from the computer's memory and can sometimes resolve unresponsive startup states.

Turn off the computer.
Disconnect the AC power adapter from the laptop.
Remove all accessory and peripheral devices (such as USB drives, memory cards, printers, or external monitors).
With the AC adapter unplugged, press and hold the power button for approximately 30 seconds.
Reconnect the AC adapter, then turn on the computer to see if it starts
