Windows 10: BSOD at start up at random. mainly for non_paged_memory.

**Reznag** · 25 Mar 2017

Hi, long time reader but, first time posting.

Because, i can't for the life of me fix my BSOD.
The system is brand new from October 2016.
i7 6850k
Asus deluxe X99 ii
Corsair vengeance 64gb ram
2 x Xtreme gaming 1070 in sli
Corsair AX1200i psu
2 x Samsung SSD
and a 3tb hdd.
27" Samsung 4k monitor.

also, i have a sim racer set up. so, i run a second screen 43" led another keyboard and mouse and a logitech G27 steering wheel.

So, the BSOD doesn't always happen at every start up, it could maybe happen 2 out of every 10 times.
Sometimes, BSOD happens and then it loads fine when it restarts itself. other times BSOD may happen 2 or 3 time in a row and then start fine.
Now, the BSOD doesn't happen all the time. it can go a few weeks without happening and i haven't changed anything in the system at all.

Things i have done to try and fix the issue.

reinstalled window
restore bios back to factory with no over clock
memory tested the ram sticks and tried one at a time
tired just one gpu.
clear cmos
pulled everything off the board and made sure they were seated in tight when re installed.

I have stressed test the system with 3D mark with no problems. I have played long gaming sessions of over 3 hours. I use Photoshop, Lightroom and Autocad and still the system never faults to a BSOD or any other faults.

so, if someone thinks they have the solution for me i am all ears.

All dumps indicate a problem with IOMap64.sys.

Code:

BugCheck 50, {ffff9a80ff9fa1a6, 0, fffff80c6a723377, 0}
*** WARNING: Unable to verify timestamp for IOMap64.sys
*** ERROR: Module load completed but symbols could not be loaded for IOMap64.sys
Could not read faulting driver name
Probably caused by : memory_corruption

Driver Description: ASUS Kernel Mode Driver ?Asus Smart Doctor/iTracker 2 Asus GPU Tweak and GPU Tweak Streaming from this link: Solved BSOD after sleep, restarts, driver_power_state_failure )
Driver Update Site: http://support.asus.com/ServiceHome.aspx?SLanguage=en

Try removing it, see if that resolves the problem. If yes then see if you can find an updated version or leave it removed if you can get by without it.

i was running Asus Ai suite 3 but, killed it now. i also, saw Corsair link can pose a problem as well. so, it gone as well.
the only trouble i am having is getting of the IOmap64.sys file. it keep saying another progra, is using this file.

any idea how to delete?
