I just setup the MS Debug utility. I haven't parsed it out yet to see what it says. However, while I was checking into to things, I noticed a few things...
1) Not really an issue, but the "exhaust" fan on the rear of the case is actually an induction fan and it is blowing into my CPU fan. (Two fans blowing against each other). that explains the mild CPU temp variations and the slightly lowered fan RPM.
2) My video card is emitting a subtle 'ticking' noise. This may or may not be an issue of relevance or perhaps leading to a future problem.
3) I checked my NewEgg info and I actually did a very noobish thing. Several weeks before purchasing I had selected a different mobo and an actual matched set of DDR1066. When I was reviewing my wish list I had made some modifications and the Crucial memory I wanted was out of stock so I browsed through and picked a "similar" set of OCZ Reaper memory. I had not realized that the Voltages differed. So, I set the EPP to manual and changed the DDRII voltage settings from 1.8v to 2.1v and so far, so good.
--- I'm now waiting for any possible side-effects to this. I'm safely assuming there won't be any because this is the rated voltage for these DIMMS.
4) Until just within the last 2 hours have I had to use the Reset switch. Upon doing so, my system fans sped waaaay up. At least 2000 RPM each. So now this is something else I'm needing to inquire.
At least for now the instability issue seems to have ceased. The noise emitting from my video card has me slightly concerned, the system fans speeding up when I use the reset switch, and any possible side-effects from increasing the voltage. (The increase of the voltage from the default to 2.1v has me concerned only because this board was designed for voltage-matched DIMMS, which these are not.)
