System not restoring power correctly after resuming from sleep

[cto520]

Hello,

I have a MSI Titanium Z170A motherboard with the latest BIOS firmware.
NVIDIA GeForce Graphics Card with the latest drivers installed.

https://us.msi.com/Motherboard/support/Z170A-XPOWER-GAMING-TITANIUM-EDITION.html#down-bios

I noticed after I resume my PC from sleep.some devices such as USB and Video Card do not wake up and I have to reboot my PC inorder to use it again.

I have a meter on my USB port showing .30 Amps before sleep and around .10 Amps when waking.

In Windows Power Settings:
Selective Suspend is Enabled for USB
Link State Power Management is Off.

In device manager, each USB Root Hub has the option unchecked: Allow the computer to turn off this device to save power

I unplugged all USB devices except the keyboard and mouse.

Lastest Chipset drivers are installed.

I have tried backing down a BIOS version as well.

Lastly, when I run powercfg /a, this is what I receive:

The following sleep states are available on this system:
Standby (S3)

The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.

Standby (S2)
The system firmware does not support this standby state.

Hibernate
Hibernation has not been enabled.

Standby (S0 Low Power Idle)
The system firmware does not support this standby state.

Hybrid Sleep
Hibernation is not available.

Fast Startup
Hibernation is not available.

Any ideas what is going on here?

Have you tried running powercfg /sleepstudy and looking at the Sleep Study report file sleepstudy-report.html?

Looks like when it went to Standby:
Entry and exit reason = unknown
TargetState 4

When it I tried to turn it on after it was on standby:
BootAppStatus 0x0
