Hello all! I've had this board for about a month now, and I think I've killed the poor thing. I've been running my 146 Opteron on it at 2.8-2.9GHz 24/7 for the last couple of weeks. This morning I left the house and my computer was happily folding away. I returned this evening to an ominously quiet PC... It had switched off! "Power cut," I thought, but on trying to turn it back on all that happened was something made a quiet 'click' noise, the fans jogged about a quarter turn... and that was it. Oh dear. I've tried everything I can think of. I reset CMOS, going so far as to remove the battery for an hour. I've disconnected absolutely everything in turn from the mobo and PSU - graphics card, sound card, disk drives, fans, RAM, even the CPU, and it's always the same. No beeps, no fans. Just the little orange standby LED. The LED by the RAM slots is off at first, then comes on with a click when I press the power button, but that's it. I've tried another PSU as well - same problem. Have I made some glaring omission? Or is it, as I fear, a very dead mobo. Advice and commiserations welcome, lol.
