Okay, this is the second board I've gotten in the last few weeks that should work, but for some reason doesn't. I decided the first one was DOA, but this one does the exact same thing - the green standby light on the PCB turns on, then when I hit power the CPU fan spins up, but nothing comes onscreen. The monitor light does not change from amber to green.
At the beginning of July I bought this 200W PSU to replace the aging 145W unit in my Aptiva. No problem with this upgrade, it runs my K6-2/450, two hard drives, one optical drive and three PCI cards just fine. The first board I tried a few weeks ago (an Asus A7S266-VM) wouldn't post with this 200W unit, and today another one I got (an Asus A7S266-VM/U2) does the same thing as the first (see above). I'm only trying to boot the board, one or two DIMMs, and a Duron 750. I've tried the integrated video and a PCI video card. This has been both on a cardboard box and in the case, for both boards.
Is it possible the PSU just can't provide enough boot juice? That would mean the first board maybe isn't dead after all. I tried the old 145W unit for giggles but that changed nothing. Oh and before you tell me to stop being cheap and go buy a case+PSU combo, I'm going to, possibly as early as tomorrow. I'd just rather know if I ought to test this idea first (for free) or try something else.
I remember Googling recently about this problem and finding someone who was going through the same thing (with the same board). He fixed it by changing the PSU, and felt that his first unit didn't give enough startup power. I'd be a bit disappointed if this was true. I've got a friend running a Barton 2800+, AIW 9800 Pro, two hard drives, and one optical drive, all on a 200W unit. I've seen it myself.
