Hi Guys,
Purchased this mobo on eBay from a chap with excellent feedback. Said there were no issues and offers to accept returns for a short period of time. I do not suspect for a moment he'd sell his soul for so little. I have looked at the board pretty carefully under magnification and it is in beautiful cosmetic condition. Choyo and G-Luxon caps look fine. The only evidence of use is the slight gouging of the keyboard and mouse connectors. Anyway I have tried to POST this board 20 times and of those 20 times it POSTed once. Let me explain.
I'm using known good ram, cpu, agp video card, power switch and power supply with motherboard on an insulated surface. Before pushing the power switch, debug card shows 3.3, 5 and 12V power is present where only the standby power light should be on. Video card and cpu fans are turning.
Hitting the power switch changes nothing, no numerals on the debug card, no BIOS beeps. At this point I clear CMOS and double-check all jumpers, then go through the circus of changing every component one at a time without success.
Finally, I try it without a video card. For the first time only the standby power light is on and the fans aren't turning (progress, I think). I hit the power switch and the debug card starts scrolling through the POST procedure, but of course it's going to stall because there's no video card. I use the power switch to turn it off (the first time that has shut it off). I'm thinking there might be a problem with the AGP port so I try it with a PCI video card. Back to the same old problem; 3.3, 5 and 12V lights on and CPU fan turning. Hit switch, no POST.
So I remove the PCI video card and try to duplicate my previous POST without any video card. Result is same old horse manure. Three lights on and fan spinning before hitting the power switch. In fact you don't even have to have the power switch connected.
There you have it, one POST in twenty, but I think the board might be made to work because of that one.
I'm looking at the world through capacitor colored glasses and thinking I'll install new Rubycons and Panasonics but I wonder if that will help. Can you guys think of anything else I should be trying? Have I described a fatally damaged mobo? By the way, my test equipment is limited to a digital multimeter.
