Exception code: 0xc0000005

Howdy! Thanks for taking the time to look at my issue.

I have been building computers for a while but this one has stumped me and I would love any feed back you could provide.

Specs:
NVIDIA GeForce GTX 970
Intel(R) Core(TM) i5-4590 @ 3.30 GHz
ASRock H97M-ITX/ac LGA 1150
2 x 8GB DDR3 1600
Windows 7 64-bit Professional

Example Error:
Faulting application name: igfxCUIService.exe, version: 6.15.10.3993, time stamp: 0x5448df5f
Faulting module name: igfxCUIService.exe, version: 6.15.10.3993, time stamp: 0x5448df5f
Exception code: 0xc0000005
Fault offset: 0x000000000000eda8
Faulting process id: 0x454
Faulting application start time: 0x01d0dd0a1416c404
Faulting application path: C:\Windows\system32\igfxCUIService.exe
Faulting module path: C:\Windows\system32\igfxCUIService.exe
Report Id: 53077f3d-48fd-11e5-af7b-4cbb58b5c356

This issues only seems to present it self in 64 bit applications. Strangely though, plenty of 64 bit applications run without fault.

Steps have taken to resolve the issue:
Flashed the BIOS to versions 1.7 and 1.8
Validated the RAM speed to be 1600
Removed the video card and used the on board chipset
Replaced the RAM with a 3rd, known to be good, stick
Ran "sfc /scannow" with no errors.
Ran a memory diagnostic with no errors.
Ensured all drivers are up to date (chipset, video, etc)
Ran Intel Diagnostic Tool with no errors

From what I can tell, I have narrowed down the issue to:
- a bad driver that I still haven't resolved
- a bad Windows installation (unlikely considering some 64-bit apps work)
- a bad motherboard

I have fired off an email to ASRock asking for any additional help they could provide but no response yet.

Thanks for your help!
 
Another example error once I removed the Intel Graphics driver:
