Windows 10 IOMap64 BSOD Errors

[DrChris]

Hi all

I get IOMap64 BSOD when booting very often. I'm not too sure if these are related to hardware [i.e. overclocking] or a software [like USB drivers or ASUS software]. I went ahead and removed the ASUS AI III software just now just in case - but I would much appreciate if someone had any insight as to what is gone wrong.

Thank you and happy new year to all!

I can take a look at it when I get home unless Kemical get's on before then.

 

[DrChris]

Brilliant; thank you Nee. No rush.

This could be an issue relating to bad memory, AV or file system corruption. I'd start by running memtest on your RAM then try disabling your AV if the 8 passes on the RAM are successful.

Hi,
Bugcheck 50 can be caused by a number of issues namely, drivers, Hardware (usually RAM) and AV suites to name but a few.

You do have a driver appearing in the Stack which is almost a sure sign that's the culprit:

IOMap64.sys Thu Oct 23 01:52:12 2014: ASUS Kernel Mode Driver ?Asus Smart Doctor/iTracker 2 Asus GPU Tweak and GPU Tweak

Please remove to test.

If the bsod continues then follow Neem's advice and run Memtest86

 

[DrChris]

Thank you both.

No Antivirus installed so that rules that out. Also, I did a completely fresh installation earlier this week to also eliminate file corruption as Nee suggested - so while it might be something relating to any of the software/drivers I have installed since, the chances are lower.

I have just now removed the ASUS software as suggested by kemical; and run windows' own memory diagnostic. According to MemoryDiagnostics-Results in Event Viewer: The Windows Memory Diagnostic tested the computer's memory and detected no errors.

But - I still have a suspicion that it could be the memory or perhaps the compatibility of the memory with my motherboard. Maybe an idea is to switch XMP profile off and apply the timings manually. In any case - I will run Memtest86 as suggested and report back.

Appreciate the help.
Chris

Maybe an idea is to switch XMP profile off and apply the timings manually.

Depending on what Memtest86 reports I'd leave the settings for now.

I will run Memtest86 as suggested and report back.

Sounds good. Thanks for the update.

 

[DrChris]

Kemical - once memtest86 completes - would you be able to take a look at results at all? [According to their instructions, the results generate a \EFI\BOOT\MemTest86.log file which I can attach if needed.]

 

[DrChris]

Depending on what Memtest86 reports I'd leave the settings for now.

Agreed. I've just checked through CPUz and Bios XMP does accurately define timings correctly for all 4 modules. So I'll leave settings intact for now.

Sure no problem although if there are error's they are usually easy to spot.

 

[DrChris]

Kemical/Neem - happy 2017 folks.

As a short update - 12 hours of memtest86 later [and through the change of the new year], the report came out clean [copied below as I'm not able to upload an .html file].

Which does make me wonder if indeed your initial suspicions that it could be ASUS AI Suite software related was the culprit. In any case, for now at least, since removing all traces of ASUS software, the computer seems smooth.
I'll monitor and advise if something else comes up. In meantime - thanks a lot to both of you
