Random restarts

[mate]

Hi, my PC sometimes restarts (not so very often) while playing games. I've managed to get the minidump of my latest PC restart but I am not familiar with that. Maybe someone can tell me what is causing that restarts
Here it is:

Use !analyze -v to get detailed debugging information.

BugCheck 1000000A, {0, ff, 0, 806e2ea0}

Unable to load image AmdK8.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for AmdK8.sys
*** ERROR: Module load completed but symbols could not be loaded for AmdK8.sys


Probably caused by : hardware ( AmdK8+3552 )

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 00000000, memory referenced
Arg2: 000000ff, IRQL
Arg3: 00000000, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 806e2ea0, address which referenced memory
