Hi all, thx for the quick replies.
I forgot to mention the most important observation:
If the PC is off for approximately 24 hours or so, that is when it'll perform those exact beeps as mention in my post. But after, any subsequent reboots/power cycles are ok with no beeps whatsoever.
It's as if, as the PC "warms" everything is fine.
We've ran extensive memory tests, such as Sandra, windows Index,... and everything always comes up just fine ?
I will check possible "seating" issues of any ram, peripheral cards, .....
