Since I had an Intel branded board, I thought this was kinda strange, but did re-flash the BIOS (by the way, it goes so smooth with the software supplied - never had that ease of installation before), and re-tested the known problem applications. Flawless, no problems, and much faster execution of processor intensive sections.
I am a "happy camper".
Glad things haveworked out for you with this. I guess the thing to first recommend whenever we get an HT problem in the Threading Forum is to suggest a BIOS upgrade.
Thanks for the information and testimonial.
