AW9D MAX is not stable

[Adhesion]

spec:
AW9D MAX
HD 2900XT
C2D E6600
Sound blaster Audigy2
Enermax liberty 620wat
BIOS 1.5/1.3 (i have tried all offical bois besides 1.4)

i have had this board since just after it came out in the uk. i would have to say it as never been 100% stable. I get random reboots after post (at stock clocks) at startup and random restarts when starting games ups. for example, i downloaded ETQW demo and installed it but i can't run it for more than 30 seconds without a BSOD. i have tested my ram and video card in a ASUS P5W DH and they work fine. memtest shows no errors.

the board is "random" in a strange ways, it could be fine for a week and then just do random things. some time one of the network ports dissapears, i restart and it's back again.

Enemy terrory quake wars (demo) is the only progam that constantly blue srceens every thing else is random or video driver related. so i am finding it impossble to screw down the exact cause of the issue. is anyone else having these issues, or am i alone?

It doesnt sound like a board fault to me.
It seems more likely there is a conflicting piece of hardware.

What OS you using?
Have you tried the Audiomax card?

yeah i have reinstalled a few times and used the audio max sound card instead of the audigy 2 but it as no effect on system stability. when i first got the board the audio max sound card was really bad, you could hear interference, the same interference i had with my IC7-G on board audio, it was like a soft ticking sound in the back ground and in games the audio was just a mess, sounds were coming from everywhere. with the latest drivers from Realtek the directional audio is far better now, still not on the same level as a audigy tho.

This machine is almost identical to my brothers P5W DH build except ram manufacturer and mother board. his machine works and is stable, my components work in his board. it could be i have a bad board as i have not seen any posts else where of this sort. but the issues are so random i can't pin it down and be 100% certain.
