Win 11 crashed After BSoD error. stop code : kernel security check failure

Question

I was working on my laptop and suddenly a Blue Screen error showed up today. After trying Ctr+Alt+Del and other resorts, since the error window didn't even budge, I directly shutdown my laptop. Now, when I'm trying to turn it on, the system is starting, fans are working but the display is totally blank with not even boot up graphaphics showing up. I use hp 14s ryzen 5 laptop with dual boot win 11 and linux

From the above pic, earlier when I used to use my laptop, the led used to blink but now it is static

Answer 1

The screen is still black.

I also wanted to know what does the stop code : kernel security check failure imply?

Answer 2

Honestly I don't but it has become a common problem lately with Windows where just a black screen appears and not even the PC manufacturers logo screen appears on startup, if you start your laptop and wait a few minutes to give the laptop time to start, if you shine a light into the screen, can you see Windows has actually started, but the screen is black?

Answer 3

Yes, I think so. Btw, do you have any idea what could be the problem here

Answer 4

In that case, you do need to bring your laptop to a PC Repair Shop, you will not be able to fix this yourself.

Answer 5

The display is not showing anything, no cursor or hp logo, nothing when I'm pressing the power button.

The laptop was working fine till around 2pm when the blue screen showed up.
