It could be the motherboard or CPU, but try unplugging all USB devices and removing all the internal cards that you can, first. If it boots okay then, try adding them back, one at a time, until you find the offending device. -- Rich

If you reseat the CPU, be careful with the heatsink. I have pulled out an AMD chip out of a socket with the socket engaged by trying to remove the heatsink. The heatsink compound can get gooey enough to act like a weak glue.

I reserved Higgins Labs 230 again, same place as last month. On Mon, Oct 08, 2012 at 04:41:23PM -0400, Tim Keller wrote: > Chuck, > > Where will this meeting be held?

Well, brand new power supply and the system behaves the same problematic way as before. So next try is the memory, as another list reply suggested. I've had memtest86 running against both DIMMs for 47+ hours and counting, 70 total passes so far, and 0 errors. Remember I'd already tried removing first one DIMM, then the other, and the problem repro'd either way. So by these measures it'd seem the memory is OK? I know some mem problems take days to show up so I'll just leave this running for a couple more days anyway. Not much more I can do here, as I've seen repros with most everything else unplugged so I'm now thinking it must be the motherboard. Perhaps I will try reseating the CPU--haven't done that yet. Recall the system is having trouble POST'ing: it hangs at various points before BIOS POST completes, i.e. I don't get a confirming 'beep' at end of POST and in some cases the monitor won't wake, other cases the BIOS splash screen stays splashed, etc. The full original email is here: http://mail.wlug.org/pipermail/wlug/2012-September/008059.html Anyway, if anyone has other ideas here I'd welcome them. Thanks again, Brett

Chuck, Where will this meeting be held? My current demo setup is two pcs... I'm probably going to need help depending on where we have it. Thanks, Tim.

Fantastic idea! Plus if it's on Wednesday the 10th I should actually be able to make it for once...

That's a great idea. I do lots and lots of virtualization stuff.. I'd be willing to do some research, setup a demo and do a talk about OpenStack. Chuck, what do you think?

How about the cloud -say OpenStack. I see references to it. -David On 10/04/2012 03:38 PM, Tim Keller wrote: > Hey Gang! > > I presume we're having a meeting on the 10th?
