Laptop Crashes when plugged in, continues crashing randomly when turned on again

My laptop crashes when I try to plug it in, within 2-3 minutes or sometimes an hour. By "crashes" I mean the screen just goes grey in color and all background activity crashes(with no cursor on-screen). Rarely instead of the grey colored screen it shows some BSODs.

Here are the following codes I have got:
page fault in nonpaged area
kernel security check failure
kmode exception not handled
critical process died
memory management

I tried the following fixes:
purchased brand new RAM sticks, ran /chkdsk scans, clean installed windows, cleaned motherboard with IPA 99%(no burns or discolorations),  ran '/sfc and /DISM restorehealth' scans and found no corrupt files, repasted the chip, stress tested GPU, Clean installed graphic drivers(using DDU Tool). 

Also used tools like "WhoCrashed" to analyse minidumps, but the tool only recognizes the minidumps of BSODs. There are no minidumps of the grey screen crash.

Also noticed how the two indicator LEDs on the side of the laptop, One representing drive usage and One representing power. The LED that represents drive usage blinks randomly when laptop works normally. But when the grey screen crashes, It stops blinking. Even when trying to Boot after that, I cannot even boot into BIOS sometimes. The power LED alone remains on.

Hi @Adarsh_Pillai1,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

You’ve done the kind of testing that most users don’t, and the consistency of failure on AC power is a huge indicator that this is not just a Windows or RAM issue; it can be related to hardware on the pc.

Please try running the Hardware test on the Pc and let me know the result to help you better.

Extensive Test - 
1. Hold the power button for at least five seconds to turn off the computer. 
2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key. 
3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests. 
4. Click Extensive Test.

I hope this helps.

Take care and have a good day.
