Do the following...

How to find and post your Minidump Files:

My Computer > C Drive > Windows Folder > Minidump Folder > Minidump Files.

It is these files that we need (not the folder). Attach to your next post the five most recent dumps. Notice the Manage Attachments button at the bottom when you go to post the next time. You can Zip up to five files per Zip; if you only have one or two you don’t need to zip them, just attach as is. Please do us a favor and don’t Zip each one individually.
 
If you have not made any changes to this PC at only two weeks old I would return it to the supplier without hesitation.

The error code 109 is often a faulty device driver but that is not likely in a new PC if you have not added anything, the other more common reason is hardware and the most likely thing is the memory. Take it back and get it replaced.

CRITICAL_STRUCTURE_CORRUPTION (109)
This bugcheck is generated when the kernel detects that critical kernel code or
data have been corrupted. There are generally three causes for a corruption:
1) A driver has inadvertently or deliberately modified critical kernel code
or data. See (URL)
2) A developer attempted to set a normal kernel breakpoint using a kernel
debugger that was not attached when the system was booted. Normal breakpoints,
"bp", can only be set if the debugger is attached at boot time. Hardware
breakpoints, "ba", can be set at any time.
3) A hardware corruption occurred, e.g. failing RAM holding kernel code or data.

Arg2: b3b7465ef173f846, Reserved
Arg3: fffff80003282000, Failure type dependent information
Arg4: 0000000000000001, Type of corrupted region, can be
0 : A generic data region
1 : Modification of a function or .pdata
2 : A processor IDT
3 : A processor GDT
4 : Type 1 process list corruption
5 : Type 2 process list corruption
6 : Debug routine modification
7 : Critical MSR modification

I would put my money on that being faulty RAM, return the PC and get it replaced.
