I installed a new P6T Asus Mobo with Windows 7 64 bit and a core i& 920 processor. It worked fine, but I wasn't able to run the Asus utilities, so I thought I needed to update the bios.
I ran the Asus update utility, it told me I was running a Feb '09 bios, and gave me the option of updating to a March '09 bios or an April '09 bios. I chose the April bios.
I got the most recent Win 7-64 Probe II download from the Asus site and installed it, but when I launch it, it says, "Access violation at address 004D8C9 in module "aaCenter.exe. Read of address 0019E83D."
