Question about ASUS Intel 850 Chipset P4T-E (P4T-E/WOA) Motherboard
I just fixed one of them, a P4T-E that was dead. I bought it for two bucks as is for parts. Turns out I found a transistor with a base-emitter short, so I replaced it. When I plugged it in again it started beeping so I fed it a video card and ram. Check Q12 by the secondary IDE. I used a TIP122 for replacement, it is 8 amps and the fryed one is 5. It is larger and has to be crammed in but it is heavier duty. So for two bucks I got a working Asus P4 board! That transistor regulates the 2.5 volts for the rambus, so if it goes the ram doesnt get the right voltage..

Try these steps-
1. Shut down and unplug ac cord to power supply
2. Pull main power supply cable out of mother board (20 pin sometimes labled p1, it is largest of power supply connectors)
3. Pull 4 pin connector from power supply to motherboard.(2 black wires and two yellow/blac wires in this connector.
4. Remove cmos battery then using paper clip or screwdriver short the 2 battery contacts together. (this erases cmos info that can become corrupter preventing boot up)
5 put everything back together and try starting up.
I've had some succes with this when other techs proclaim the mother board is dead, hope works and good luck

Check that your display card is seeted properly and your ram,if you have two ram chips remove the chip in socket no.1 and replace it with the other chip.
