I read around on this because I had the same issue and indeed the fix for many was to reinstall the drivers for the GPU which worked for me. It also says it's a part of ASUS PC probe software. I also read that uninstalling AI Suite won't really fix the issue but you can remove the offending files manually by navigating to the following folders though this likely isn't the true cause of the issue.
IOMAP64.sys in three places so far
C:\Program Files (x86)\ASUS\VGA COM\1.00.21
C:\Program Files (x86)\ASUS\GPU TweakII
C:\Windows\System32\drivers
The other possibility is that you may have a bad stick of memory so you should use memtest to find the offending module. This issue has come up many times in the past with bad memory being the most likely cause.
