crash dump file: C:\Windows\Minidump\081311-21543-01.dmp
This was probably caused by the following module: dxgmms1.sys (dxgmms1+0x1CE31)
Bugcheck code: 0x3B (0xC0000005, 0xFFFFF88005312E31, 0xFFFFF88008C6C080, 0x0)
Error: SYSTEM_SERVICE_EXCEPTION

Bug check description: This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system which cannot be identified at this time.

crash dump file: C:\Windows\Minidump\081111-25428-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x7FD00)
Bugcheck code: 0xC5 (0xFFFFF8A001961000, 0x0, 0x1, 0xFFFFF80002C13406)

description: NT Kernel & System
Bug check description: This indicates that the system attempted to access invalid memory at a process IRQL that was too high.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver which cannot be identified at this time.

my gpu drivers and mobo bios and chipset are all the latest, they occur at random times, usually quite soon after booting up from 1min to like 20 mins ish, could be loading any program be it browsing or playing a game, im not very good at reading the dumps. please help!

My hardware is all only 4-5 months old, have only been having this issue he last month-ish, mustve installed some software or some driver or something! last thing i have added was my usb wireless adapter, a tp link tl-wn722n

Oh sorry, heres my zip file, in performance monitor the file menu gives me the choices of options and exit

Thank you for the reply! I have followed your steps to the best of my knowledge, pc has booted up fine, but the BSOD's came and went. Is there anything i should do to see if the issue remains or continue with normal usage and report back if i suffer another blue screen?

Sorry, what i meant was that they didn't happen every time i booted up, was usually once every couple of days or so

Okay will do, thanks for the help :)
