BSOD when coming out of sleep

The crash blames the graphics driver here as faulty.

Code:

fffff880`09cd2c00  fffff880`04cf2f01Unable to load image igdkmd64.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for igdkmd64.sys
*** ERROR: Module load completed but symbols could not be loaded for igdkmd64.sys
 igdkmd64+0x4e3f01

But it is already in its latest version.

Code:

fffff880`0480f000 fffff880`04d2a1a0   igdkmd64 T (no symbols)
