Based on supporting similar Optiplexes: is there a chance that "low power mode" is set to "off" in the BIOS and/or "Wake on LAN" is set to "on"? Screenshot here:

I doubt there are but while you're there… FWIW we're using Supermicro chassis/mainboard/PSU components (Intel Xeons) for our 7 Rivendell systems (soon to be 9). But our first test box was a recycled Optiplex 745 small-form-factor desktop, which shouldn't be too different from your 740 (guessing here based on the 745s, 755s, 760s, and 780s we have). Want to rackmount everything in a central place? Instead of KVM runs, try a Teradici PCoIP card from eVGA and a PCoIP thin-client box in the studio. We've done this and it rocks. No drivers needed unless you need a USB CD-ROM drive at the thin-client box (we have remote-start CD players in the chain via the audio router, so that was not needed for our setup). You might check the mainboard for bulging caps like someone else suggested -- might try running a Linux-based "live" CD of some other flavor of Linux to ensure it isn't your particular distro. -- Dan Willson | Senior Systems Analyst Office of Public Relations and Marketing WBHM FM 90.3: Your NPR News Station UAB | The University of Alabama at Birmingham AB 1320 | 1720 2ND AVE S | Birmingham, AL 35294 P: 205.975.2825 | E: [email protected]<mailto:[email protected]> uab.edu<http://www.uab.edu/> Knowledge that will change your world On 04/04/14 16:58, Larry wrote: Larry <larry@...> writes: I have searched the archives and no one else has posted this problem that I can find. I have installed the Paravel broadcast automation appliance this week and the mouse will freeze/stop working after just a few minutes of use. I have to reboot to get the mouse back but it always freezes. I have installed this on a Dell Optiplex 740 dual core 64 bit processor, 2GB Ram, 1TB hard drive, ALSA compatible M-Audio Delta 44 sound card and USB mouse and keyboard. After the mouse freezes the USB keyboard will still work using the up/down and F keys but the mouse stops no matter what USB port I use. Appreciate any help. This Dell Optiplex 740 has been running Windows XP reliably with the same mouse and keyboard since 2009. I have tried 2 different mice and they are USB and it is not the mouse. I have figured out the problem is all the USB ports go dead when this happens. When the mouse the stops, the keyboard works for a while but If I unplug keyboard and plug it back in it will no longer work at all. Nothing works in any of the USB ports after the mouse stops. I have tried re-installing the appliance, removing the sound card, removing memory one stick at a time and the video card and the USB ports will stop working. I have downgraded the BIOS to 4 former versions and that makes no difference. There must be something in this Dell chipset that is conflicting with CentOS. Nothing shows up in dmesg or the /var/log/messages file. My next step will be downgrading the the version 1 appliance but I don't have high hopes. What brand and model computer are you guys using that have success with Rivendell Appliance?
