A sleep I can't wake up from.

Hi,
I've been running Windows 7 Ultimate for the better part of a year now. For about the last week or so now, my computer is going in to (what I assume is) sleep mode at the most inopportune moments. No amount of anything will wake the computer from its sleep - not the keyboard, mouse, ethernet activity (which should keep it from falling asleep in the first place) - only a hard reboot will bring my PC back to a state where I can use it.

Some of the things I've tried, so that people don't answer with "change your power plan settings" or some such thing. If it was that easy, I wouldn't be here asking for help. I'll restate that I've been using the same Win7 Ultimate install on the same PC for a year now, and it's only in the last week this has been happening.

Anyways, I have:

1. Verified all my power plan settings;
2. Disabled any screen saver;
3. This is an older desktop, not a laptop, so hibernate and hybrid sleep options are not even present. Nevertheless, I've followed this guide and this one for disabling both.
4. Used device manager to specify my keyboard, mouse, and ethernet card as "wake up" devices. Also used the command line to manually set these as "wake from any state", only to have them all not work.
5. Tried changing group policy and eliminating sleep/hibernate from the user group.

As I said, it's only been doing this for a week or so now. All my drivers are current. All my system updates are current. I haven't installed any new software. I was literally watching a movie on a laptop the other night when everything froze, and it took me a half hour to get back to the desktop and realize it had gone to sleep. I've had to hard reboot it a dozen times since then because it keeps doing it.

Anybody have any ideas for me?

Did you try system restore? Actually sounds like a bad power supply. Good luck to you.

Power supply's good. I should add this only seems to happen when I'm streaming media from the attached storage to one of my laptops. When I wake up in the morning or when I get home from work (in other words, after 8hrs or so of inactivity) everything is fine.

Games for Windows Live.

The laptops I'm using to access the shared media on this computer are all running Linux, and accessing the shares with Samba. Somewhere along the line, somebody figured out that GFWL has some sort of conflict with SMB, causing a wide variety of seemingly unrelated complications.

It would seem that this was one of them. I unistalled GFWL three days ago on a hunch and my computer hasn't crashed since. Subsequent research led me to the info on GFWL/SMB related madness.

Case closed.

I have been experiencing the same problem. I do run Linux Ubuntu, but that is set up as a dual-boot. I do not have (at least I don't think I have ) GFWL installed, nor am I sharing stuff with Ubuntu computers. My problem still exists...
