Honestly, since you've already flashed your BIOS, I'd just try and update drivers on all the essential components of your computer. If the problem still continues, I'd say its time for a reformat of your drive. Just save up all your important stuff and pop in your Windows XP install disk and go right on ahead.
How old is the board? New?
What are the temperature readings in your BIOS? and in Windows?
So this was happening before you updated your bios?
Have you overclocked anything?
Have you changed any of the settings in your BIOS?
At what point do you get the BSOD? (windows boot up, after login?)
Ive been running this board for over 6 months now, and i can say that i have never seen that error.
If everything is at stock (cpu speed, ram) and you are getting any error at all, its obviously not a good sign, so you might want to think about RMA'ing that board. Looking at the specs, i dont see anything that out of whack so you should have no problems.
I cant think of anything off hand that would cause problems...you should have a pretty kickin system there. After you answer those questions, i might have an idea on stuff to try...but until then...good luck.
I seem to have narrowed down the problem..........Thanks to "acronis true image" I made a fresh disc image when i 1st installed XP..........seems as though it was one of two programs....either "Hamachi" its online networking software or speedfan...........think its Hamachi
