Nope, no beeps. Edit: and yep, I tried both with and without memory.
God, I've had three motherboards and one was faulty. It's too late to return this one now. Grr
.
I'll try the PSU with my Socket A board, because it was working with that and I've hardly used it since (well, I haven't been able to).
Great, more money to spend on another PSU if this one's not working.
Thanks.
