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.

I tried to install clean version of Windows 8.1 and Windows 10 pro pro system in legacy mode that EUFI with usual problem. The motherboard features the latest bios with all settings from stock car version available in 2601 proved even with earlier versions. I tried to disable hibernation, disable Quick Start, disable power management of the general devices, disable power management options in the cpu section configuration in the bios (and quite cool, C16 STATE ECC.), I upgraded to the latest version all drivers and firmware for all devices on the machine, I personally set the latency of the standard ram because it gave no real results present in the bios setup to the default settings. I tried watt power supplies with more powerful as a corsair 600w, video card before 8 years ago to see if it was the PSU issue but still same problem, and I tried clean install with a traditional SATA hard disk to see if the culprit was L 'ssd .
2 issue:
      The fans at the reactivation of the suspended starting at a very low speed, turn off the audience led and stop for seconds then depart to the natural level. Proved that three fans. Immediately after resuming the error appears.
Sometimes the PC fizzes with no possibility to use a mouse and keyboard, and forcing you to shut down your pc from power button.I would like answers and specific techniques to solve this problem. I thank you for now. Merry Christmas from 'Italy to all

Hi,

To assist you better regarding you concern, we would like to know if your experiencing the same issue?

We're looking forward to your reply.

Someone Fixed UN spent all this time? Some of you have replaced the power supply?

@FastSteve -- I think it's not the same error, even though it's the same Event number.  Maybe they are related, but I'm not seeing how Ntfs and Kernal-Power are connected here, nor why the same number.

BTW, is there a SlowSteve?

My Windows 10 seems to be working okay so I just ignore this error.

My Windows 7 only shows one Event Id 137 and it is an NTFS error.   I'm confused even more than usual.  ;)
