System crashes when left idle

[Gremlyn1]

My system will crash when left inactive for a period of time. This period of time is not known and it has never crashed during operation. The system won't come back from the screen being shut off and requires a hard restart.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it because your description didn't include enough information. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures

At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!

Sure, I guess I should have written more in my initial report, I know better than that! Here is a more in depth run down of how I encounter the issue for now, and I'll look into running through some of the debugging procedures tonight.

1. I turn my computer on, boot with no issues into Ubunutu (only OS currently installed on the hard drive). Use the computer like normal, I don't do anything special or run any programs that are unusual. I have a local test LAMP server going I occasionally test small projects on, I run Deluge BitTorrent client from time to time, lots of surfing through FireFox and e-mail with Thunderbird. Really nothing out of the ordinary.I'll go to work or bed and leave the computer for any number of hours.

2. Well... I want it to be responsive when I come back to use it! ;)

3. About ~40% of the time I'll come back and the computer is non-responsive, doesn't matter if it's been an hour or 6... I don't really know how long it goes between working and not. I sometimes check my logs to see timestamps, but there isn't any pattern or event that seems to set it off (that I have noticed). I have the monitor set to turn off after 30 mins, the screen saver comes up after 10 mins.I usually test to see if it's working by pressing the Num Lock or Caps Lock to see if the lights will turn on/off on the key board. If they don't, I have to hard reset the computer. I've tried entering the CLI through Ctrl-Alt-F5 to reboot that way, but to no avail. The whole system is just locked.

System specs:
AMD Phenom II X4 940 3.0GHz Socket AM2+
ASUS M3A Motherboard
Corsair XMS2 DDR2 (PC6400) (4x 1 GB)
EVGA GeForce 9600GT 512MB
SAMSUNG 16X DVD±R DVD Burner
Western Digital Caviar Black 1TB SATA HDD

Everything is left in stock spec, no overclocking of any sort has ever been performed on this machine.
