How about the power capacitors and/or ic's on the board itself (as opposed the the power supply)? I have to admit, that is the first thing that came to my mind after reading the first few posts. I'm surprised nobody else went there. Of course, memory is a fickle thing and it still could be that, but I am feeling that it is something else. DaveC On 10/8/2012 11:30 PM, Brett Russ wrote:

I agree that the power supply is suspect. You can measure the voltage Alternatively, it may be easier to just try a replacement. I have a new one on the way. I'll reply here with the results. Well, brand new power supply and the system behaves the same

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.
