Okey so first of all; I'm in no way a computer expert so helping me would require to explain like im 5. I've had this laptop for quite some time now, and I only use it when I can't access my computer (I'm currently back home at my dads and didnt bother to bring it on a plane), but fixing it has been on my mind for a while and I'm hoping my fellow XI's could help me!  
  
The PC is an HP ENVY m6, about 3 y/o. I've had this bluescreen problem from the day I got it and I've sent it back for reparation five times with no luck (apparantly Norwegians cant deal with this one). I've recently completely formatted the PC and installed windows 10 on it, which by luck didnt bring any additional issues to the pc, or new bcod-codes.  
  
Here are some of the error messages I've gotten recently; 
  
IRQL not less or equal 
System thread exception not handled 
Attempted write to readonly memory 
Page fault in nonpaged area 
Memory management 
System service exception 
Kernel data inpage error 
  
Unfortunately I didnt note the codes that's in parenthesis behind the message itself.. 
  
If you need more information about the PC itself let me know! Don't really know whats important to inform about or not.
