Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not a "handsome prince"!

The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive.

Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13?

Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem.

Fedora9 on the same hardware is fine.

Problem Solved: First, quack quixote thank you for your edit. I looked at your profile and we older geeks sometimes have an advantage. I am 2 months shy of the US National Speed Limit - 70. I have worked on computers in some fashion since age 18.

Two machines with almost identical symptoms but they had different problems. Both were hardware and not fedora. The one that I posted over had a "soft memory bit." For those that do not know, soft bits are those that only fail only when stressed. Apparently, slide show screen savers can do that.

Machine two had a ram memory boundary problem. Specifically, memory strips with different megahertz rating. That machine was diagnosed as having a heat problem by a local tech at a remote office, replaced, and shipped to me. I never looked at the memory strips, I simply cleaned the machine, did rudimentary testing, and put it on the shelf. It remained there until I decided to put Fedora on it.

Maybe I will go home, look in the mirror and see if I have turned into a "Handsome Prince" after all.

Naw! Never happened. I am still just a crusty old geezer geek.

yer welcome. glad you got it figured out, and thanks for coming back with the postmortem. but don't believe everything you read... i'm either not really from 17th-century Spain, or i'm way older than it says. or, y'know, neither. :) – quack quixote May 6 '10 at 13:36

I had the same problem until the latest kernel update. I got around it by switching to VT2 (via CtrlAltF2) and then switching back to VT1. I figured it was something with how the video card was being initialized by the kernel, but never looked at the cause itself.
