Hi
I've bought a MA790X-UD4P with a Phenom II X2 550 BE to give my current M2N-E/X2 6000+ setup to my kids. Booted once in bios, looked at temps and settings for about 10 minutes then rebooted to install Windows but it never reposted.
On reboot, VGA (8800GT) fan would spin at 100%, HDD and power leds were both on and screen would go in stanby mode. Reset and Power buttons would not work either, I had to use the PSU switch to turn it off.
I then tried the X2 6000+ with the same hardware (which has been running fine for a year) and all went perfect. I installed Windows without a glitch. Since Windows was running fine on the MB, I've tried switching back to the 550 BE and tried F5, F6 and F7 BIOS version but none of those would change the symptoms.
I then tried the new 550BE in a M3A76-CM mobo and it boots just fine.
I took the 7750BE that was with the M3A76-CM and put it in the new MA790X and it would not post.
So I have a MA790X-UD4P that won't post with Black Edition CPU's but will post with a standard X2.
Can someone suggest anything else than a BIOS update before I ship this board back ?
Sorry for the lenghty post, I hope that I'm clear.
Thanks in advance
Pete
