Code:
Version	6.1.7600 Build 7600
You don't have service pack 1 installed.
Install it using Windows Update.

Code:
BugCheck 19, {21, fffff900c2109000, 2030, 1}

Probably caused by : win32k.sys ( win32k!FreeTmpBuffer+1e )
I can't find the driver responsible.

Code:
1: kd> !pool fffff900c2109000
Pool page fffff900c2109000 region is Unknown
*fffff900c2109000 size:  100 previous size:    0  (Allocated) *.... (Protected)
		Owning component : Unknown (update pooltag.txt)

fffff900c2109100 doesn't look like a valid small pool allocation, checking to see
if the entire page is actually part of a large page allocation...

GetUlongFromAddress: unable to read from fffff800038291b0
Unable to get pool big page table. Check for valid symbols.
fffff900c2109100 is not valid pool. Checking for freed (or corrupt) pool
Bad allocation size @fffff900c2109100, zero is invalid
Enable driver verifier but only enable the options: Standard settings and IRP logging step 3.
Don't enable Force Pending I/O Requests

Enable Driver Verifier to monitor the drivers.
Driver Verifier -Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

information   Information

We use Driver Verifier as it puts a stress on the drivers, and so it makes the unstable drivers crash. This should flag the driver responsible in the dump file.
It

Driver Verifier will make the system laggy, this is normal so don't worry.

Before enabling DV, make sure that you have earlier System restore points made in your computer.

If there are no points, make a System Restore Point Manually

Use the system restore that you should have created before, did you make sure you didn't enable any Microsoft Drivers?

Run a Disk Check to scan for errors

Note   Note

Afterwards go into an Elevated Command Prompt (Run as administrator) and type in sfc /scannow
If it finds errors reboot and run the scan two more times


Run SeaTools to see if your HDD or SSD is failing
