Computer won't automatically sleep (Win 8.1)

Just at first glance of the report you added shows a couple things apparently .....

<<<QUOTED from your post:

Errors

USB Suspend: USB Device not Entering Selective Suspend
This device did not enter the USB Selective Suspend state. Processor power management may be prevented when this USB device is not in the Selective Suspend state. Note that this issue will not prevent the system from sleeping.
Device Name Generic USB Hub
(What in the world is hooked into that octopus? - Generic USB Hub - http://en.wikipedia.org/wiki/USB_hub Possible driver issues?)

USB Suspend: USB Device not Entering Selective Suspend
This device did not enter the USB Selective Suspend state. Processor power management may be prevented when this USB device is not in the Selective Suspend state. Note that this issue will not prevent the system from sleeping.
Device Name USB Composite Device
Host Controller ID PCI\VEN_8086&DEV_1E31
Host Controller Location PCI bus 0, device 20, function 0
Device ID USB\VID_046D&PID_C52F
Port Path 2,2
(What in the world is hooked into that octopus? - USB Composite Device - http://www.ask.com/question/what-is-a-usb-composite-device - possible driver issues?)

.....So that apparently you have some peripheral (Printer, Mobile Handheld Sync, Memory Drive, any USB device etc) plugged into a USB port that may not be going into sleep correctly.

What is this? : (Have you used some program in Firefox to achieve your task?)
Platform Timer Resolution:Outstanding Timer Request
A program or service has requested a timer resolution smaller than the platform maximum timer resolution.
Requested Period 10000
Requesting Process ID 4308
Requesting Process Path \Device\HarddiskVolume4\Program Files (x86)\Mozilla Firefox\firefox.exe

Platform Timer Resolution:Timer Request Stack
The stack of modules responsible for the lowest platform timer setting in this process.
Requested Period 10000
Requesting Process ID 4308
Requesting Process Path \Device\HarddiskVolume4\Program Files (x86)\Mozilla Firefox\firefox.exe
Calling Module Stack \Device\HarddiskVolume4\Windows\SysWOW64\ntdll.dll
\Device\HarddiskVolume4\Windows\SysWOW64\kernel32.dll
\Device\HarddiskVolume4\Program Files (x86)\Mozilla Firefox\mozjs.dll
\Device\HarddiskVolume4\Program Files (x86)\Mozilla Firefox\xul.dll

ANOTHER DITTY:
Platform Power Management Capabilities:PCI Express Active-State Power Management (ASPM) Disabled
PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer.

WHAT MAY BE PROBLEM IS YOU HAVE VIDEOS/ANIMATIONS PLAYING AT TIME OF SHUT DOWN....

Warnings

Platform Timer Resolution:Platform Timer Resolution
The default platform timer resolution is 15.6ms (15625000ns) and should be used whenever the system is idle. If the timer resolution is increased, processor power management technologies may not be effective. The timer resolution may be increased due to multimedia playback or graphical animations.
Current Timer Resolution (100ns units) 10006
Maximum Timer Period (100ns units) 156250

Go To:

CPU Utilization: Individual process with significant processor utilization.
This process is responsible for a significant portion of the total processor utilization recorded during the trace.
Process Name FlashPlayerPlugin_12_0_0_70.exe
PID 1980
Average Utilization (%) 2.48
Module Average Module Utilization (%)
\SystemRoot\system32\ntoskrnl.exe 1.05

JUST FROM SKIMMING THE REPORT I SEE THESE POSSIBLE PROBLEMS. ONE MORE IS.....

Power states
http://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface
Global states
The ACPI specification defines the following four Global "Gx" states and six Sleep "Sx" states for an ACPI-compliant computer-system:[20][21]
G0 (S0): Working. "Awaymode" is a subset of S0, where monitor is off but background tasks are running.
G1, Sleeping. Divided into four states, S1 through S4:
S1: All the processor caches are flushed, and the CPU(s) stops executing instructions. The power to the CPU(s) and RAM is maintained. Devices that do not indicate they must remain on, may be powered off.
S2: CPU powered off. Dirty cache is flushed to RAM.
S3: Commonly referred to as Standby, Sleep, or Suspend to RAM (STR). RAM remains powered.
S4: Hibernation or Suspend to Disk. All content of the main memory is saved to non-volatile memory such as a hard drive, and is powered down.

FROM YOUR REPORT:

Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.
S1 Sleep Supported false
S2 Sleep Supported false
S3 Sleep Supported true
S4 Sleep Supported true

There is a lot of CPU power going on with running things that you may need to shut down manually or uninstall unnecessary softwares - see the CPU usages in your report and refer to this chat forum page briefly about that....

A wild guess is you have too much crap installed and are conflicts - like a zillion peripherals and too many running - and whatever you did to set up this "automatic sleep" set up I have no idea yet, and you must post that - how did you get here?
