Alienware 15 R2 Windows 10 not booting - BSOD

Hi,

i have an Alienware15R2 signature bought through a deal at microsoft store in july 2017 (warranty just voided :-( ). Since a few weeks, win 10 is stuck, The laptop start on boot goes to the connection screen and then crashes to a BSOD. I've tried all options possible to restore it, it says restore is not possible event though I'm trying toi wype everything out.

The reset is not working I'm still ending with a message saying 'there was a problem resetting your PC"

the re is no restore point so I can get any restoration back to a period of time

windos can't find any system image backup^so no possible restore

startup repair always end with "startup repair couldn't repair your PC"

on boot I have various errors :"IRQL_not_less_or_equal" or "kernel security check failure" and the laptop fans are running out like mads

I was expecting to use eventually a usb key to repair the system, but I can get any info on my windows 10 serial, no sticker on the laptop and I'm not gonna pay for a brand new W10 licence as I already paid for one, I have no recovery drive, yes I know my bad, I should have done a set....

Any ideas to help me please ?

Thank you in advance folks...
