Intel PR440FX Need Schematic

[qDomain]

I have a somewhat working Intel PR440FX motherboard out of an old PC I retrieved from my attic. When testing on my dim bulb tester it illuminated the bulbs at about 2/3 brightness (2 - 60 watt bulbs). I abandoned cautioned to the wind and switched out the dim bulbs and the motherboard powered up. It had an ATI all-in-Wonter Rage 128 PCI graphics card and a Soundblaster 64 Live Gold sound card both worked. I found the hard drive that I had intended to destroy years ago because it had a lot of personal data on it in my shed. I connected the hard drive and it booted and ran Windows 95(b). I played a few games, loved the experience, but did not want to press my luck. I opened up the power supply and found and replace one bad capacitor on the low voltage side. When I powered up the power supply with the dim bulb tester it acted as expected with the bulbs flashing then going dim. The capacitor I changed could not have been responsible for the large current draw so I checked for shorts on the connector of the motherboard. I have not connected the power back to the motherboard at this point. All of the voltage rails rested for resistance to ground in the KOhms but the 12 rail show a NEAR short of 27 ohms. I removed a few capacitors on that rail that had a higher than expected ESR, but the 27 ohm (near short) remains. There are 4 mosfets hat are common with the 27 ohm reading but they are hard to diagnose in circuit. In-circuit they appear to all be turned on, but this may be due to other elements in the circuit. Without a schematic at this point I am just grasping at straws to find this 27 ohm issue. If anyone has a schematic or any Ideas it would be helpful. Thanks.
