I've got a new system with a few good pieces, but it just will not POST.
Here's the problem:
Power comes on and a slightly loud whirring comes from the PSU for about 1 second, then spins down to an idle speed. All fans are running. The DVD R/W looks like it is accessing with a click, click, click, though no disc is in it. The monitor stays asleep.
I have tried:
Clearing the CMOS twice - left the battery out for over an hour the second time
Checking and rechecking all cabling and connections, including reseating every coupling
Disconnecting all drives; only connecting the HDD
Powering on with one stick; with no memory
Powering on with only the video card, two sticks of memory, a SATA HDD, and k/b
Connecting the PSU to the extra on-board power coupling used for when I put in three more ATI cards.
The last attempt was to swap out the processor to an Athlon 64 X2 4600
When I didn't get any POST, I tested each lead coming from the PSU and got lotsa blue love from each connection.
I feel like I got a bad mobo, but I suppose it *could* be that my PSU is advertised as NVidia SLI-ready, when I am using an ATI Crossfire board. However, I'm only using one card and all connections are covered, so why should that make a difference?
My system is listed below. If anyone has any ideas, I'd love to hear them, as I got this mobo online and returning it would mean a good, long wait plus shipping and handling. BTW - I do not have another mobo that supports a Phenom processor, so I can't test that.
