Windows 10: BSOD on startup

HelloI've been working on this BSOD but I ran out of ideas to troubleshoot the issue.I don't always get the BSOD but it is either that, or a computer freeze between 5 sec and 5 min on startup.I don't know if it linked, but the Windows Upgrade Pannel is stucked on the upgrade KB5025239 loop between download and install errors. The freeze/BSOD seems to appear faster when I open the Windows Upgrade Pannel.If that helps : everything runs correctly when I manage to boot in safe mode.I've had several BSOD errors but this one is the one coming back the most : KERNEL_SECURITY_CHECK_FAILURE What

Can't get GPU-Z to start with Windows 8.1 startup

I'm not sure how to do that. Could you list the steps for a noob?

 

Nvlddmkm.sys BSOD on startup?

The problem is the laptop (specs in signature) not rig in system specs.

Sometimes when I switch it on, Vista loads normally.
Other times, just after the horizontal 'loading' bars and before the Vista orb appears, I get a BSOD of Nvlddmkm.sys or Nvlddmkm.dll then the laptop reboots, BSOD's, reboots... it can happen like 5 times!

I've been googling all morning but apparently there's no solution to this?

It does the BSOD only during startup. Once Vista loads, it never BSODs not even during a game.

 

Startup programs not launching on startup

Replying to Brink none of that works here is why-
Step 1- No items listed in startup on task manager as stated.
Step 2- I dont have shell:Startup on the pc as it cannot be located
Step 3- I dont understand that option also the startup folder cannot be found
Step 4- No apps showing under startup on settings
Step 5- Dont have access to advanced options at all for any apps
Step 6- Doesn't work.

Thanks for trying
