memory

I've got a machine with a DQ965GF motherboard. Two days ago it started locking up hard. Ran memtest 3.3, 1.7, and TestMem 4. TestMem just freezes, memtest failed on moving 8 bit inversions. Letting memtest run eventually causes the system to restart.

I pulled memory sticks one by one, and then replaced the memory with a couple of known good sticks. No luck. I switched power supplies, didn't help. Swapped video cards just to be safe. No help.

When I start the machine I get a single beep before it POSTs. According to the manual, a single beep means:

1 beep - Refresh Error (with nothing on the screen and it is not a video problem)

I'm assuming that the motherboard has failed since it's obviously not a RAM or power issue. Do you agree?

NOTE: I also tried resetting BIOS defaults, and even flashed the BIOS to the latest version. I also ran the Mersenne Prime Test and the CPU seems to click along just fine.
