Swapped a Athlon 64 X2 for a AMD Phenom2 x6 1045t
did the swap got a black screen no beeps. I've flashed and updated the BIOS several times with different versions from the gigabyte website. Been on this for 8 hours finally goin to the forums.
I've got the 12v connector plugged in also. the CPU is listed on the supported CPU list. Any help is welcomed.
