Desktop freezes when idle

I am running win7rc 64 on a home build, asus m2a-vm mb, ati hd4670, 4 gig OCZ ram. All drivers are current win 7 or latest Vista64 drivers. Away device is disabled.

Symptoms: when my computer is in use it performs as advertised, no problems with booting lockups or anything.
after my machine sits idle for approx. 20 minutes the desktop stops responding to mouse and keyboard inputs, the monitor will turn back on. Sometimes the desktop will recover functionality in 3 to 5 minutes and sometimesit does not recover at all.
The power options are set to turn off monitor at 20 mins, sleep: never, Hibernate: never.
I have looked in all the usual places on the internet for suggestions and came up blank.

P.S. I have checked and adjust the usb and lan settings for wake settings. I have turned off all the bios settings I can related to APM and AMD Live and Cool n Quiet and the C1E setting.

I'm at a total wall Please help.

So there are no yellow flags under Control Panel > Device Manager?

Try this command-line diagnostic utility for problems with power problems.

Go to Start > Run, type cmd, then type powercfg -energy.

This will output an HTML file and look over this file for problems problems

No device manager flags.
Energy report and belarc attached

From the energy report.....

Platform Power Management Capabilities:System firmware (BIOS) does not support S3.
The hardware in this computer does not support the S3 sleep state.

I'm really not sure what S3 mode is.

Try setting your machine in Control Panel > Power Management and change the put my computer to sleep after 25 minutes.

S3 is a power suspend method. It can be set in the BIOS. Maybe it is now set to S1. Nevertheless I have my own issues with windows 7 and resuming from sleep mode I have a thread open for it right here :
http://windows7forums.com/windows-7-...p-win7-rc.html
Microsoft should really sort this power mess out

S3 is the default sleep setting for windows, I have it disabled in the bios.
Attempting troubleshooting 101: disable everything till it works then add back.
Unfortunately the problem will not resolve under any conditions.
Currently there are absolutely no sleep or hibernate options turned on and everything in the bios I can turn off has been turned off. I'm wondering if it might not be the way windows 7 interacts with the and 690 chipset I have or one of my device drivers.

I have the next 3 days off so I'll try some troubleshooting.

Yes I have noticed this too If I let Win 7 x64 Idle for to long and then come back this happens, My mouse will work, but If i double click icon or try to unhide the Taskbar the computer will sit there, Some times it will comeback work right other times it will just lock up and force me to restart,

I have All THe power save options Disable in windows short of just letting Windows put Monitor in power save mode, and it still does it,

DualCore Intel Core 2 Duo E8400
Asus P5Q Pro (P45)
OCZ XTC Vista Upgrade Edition OCZ2VU8002G 2 GB DDR2-800 DDR2 SDRAM x2
NVIDIA GeForce 9800 GT (512 MB) 185.85

it seems that my machine was fixed by a full clean reinstall of windows 7. Everything seems to work now.

I figure out whats going on and it is an easy fix. The reason this is doing this is because you need to go and change your power plan. Go to >control panel>power options>select power plan>change plan setting>(I have created >My Custom Plan)>Change Plan settings>Change everything to> never>Change advance power setting>go to each setting and change them to never>hit apply>OK.>Problem solved should be solved. I will post this in the right catagory. I just see alot of people reading this first so I figured to relieve frustration from searching. Heres the fix to the problem. I just joined this site to help fix this problem seeing this is a comon problem with no immediate fix so here it is.....blizz26 (10 yearTechnet Beta Tester)

I'm also experiencing these issues on 64-bit build 7100.

Tried this already. As a matter of fact, it's the first thing I tried back when this all started a week or so after installing RC (a month or so ago). The only thing I've been able to determine is that it happens after I leave the computer unattended for exactly 2 hours. Sometimes the clock is visible and it's easy to spot that the time being displayed is exactly 2 hours after I went to bed.

System specs (hopefully we'll have something in common):
Gigabyte GA-MA78GM-S2H
AMD Athlon 4050e (Dual Core, 64-bit)
ATI Radeon HD3200 (built-in to the mobo, but potentially could be the culprit)
6GB DDR800 RAM
CPU Frequency scaling is on.
Test Mode is on (otherwise PG2 can't run).

Edit: I managed to find a screenshot I took a couple of weeks ago. The window shown here has been edited out as to not look like a troll looking for free advertisement. Also the important part is the taskbar as it's the most noticeable thing (blanks out and icons that should be on the right side edge appear next to the start menu button).
