System Error Log Kernel-Power EventID 137 SleepState 4

Hi,

Every time I manually put my PC into sleep mode by using StartKey > Power > Sleep, another instance of this error is recorded in System Error log:

Code:

Log Name:      System
Source:        Microsoft-Windows-Kernel-Power
Date:          9/6/2017 9:26:33 AM
Event ID:      137
Task Category: None
Level:         Error
Keywords:      (4)
User:          N/A
Computer:      AO40
Description:
The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S4). This can result in reduced resume performance.

This entry in the log is the only evidence of error I can discern. I haven't noticed any performance degradation nor do I see any pop-up errors.

I'd be happy to just ignore these entries in the log unless there's an easy fix.

Thank you for your advice,

Hi there. This is not a big thing, but may be caused by the non-compatible driver. Which CPU do you have? Motherboard?

Hi HG,

Thanks for the reply. :)

Which CPU do you have? Motherboard?

CPU is AMD FX-8350

MOBO is:
Manufacturer ASUSTeK COMPUTER INC.
Model M5A97 LE R2.0 (Socket 942)
Version Rev 1.xx

...may be caused by the non-compatible driver.

Which driver do you mean?
Video adapter NVIDIA GeForce GTX 550 Ti
Driver version 22.21.13.8205

You're welcome.

Yours is similar to mine.

The CPU driver.

Hi HG,

Using Speccy, I don't see anything listed as a driver on the CPU tab.

In Device Manager > Computer > ACPI x64 based PC, I check for updates and the response is that this driver is up-to-date.

None of the entries in Device Manager is flagged.

Do you have other troubleshooting ideas?

Thank you,

Dee

Sorry for the delay. I was out of town for the weekend.

We have the same CPU, but a little different board. To compare, I have generic Microsoft driver version 10.0.15063.0 for my CPU cores.

I tested your method for placing mine to sleep. I get a different kind of error relating to the DNS server.

The only thing I can think of is to check the Asus site including their forums to see if others have your problem. Just for grins you may want to run these two:

If sfc /scannow command is unable to repair corrupted or modified system files because the component store (source) is corrupted. SFC should be able to repair the files afterwards.
