| 101794 | 2002-11-27 04:42:00 | Okay now, I've tested the ram, video, power supply in a different machine, and all are going fine. I can't test the CPU (yet, maybe). Graham, how do I short the WAN (do you mean WON) thingy? I have a three pin header, which two do I short? I also have a header/jumper labelled WOM (wake on modem?) neither WOM or WON/WAN are explained in the manual. |

| 101795 | 2002-11-27 05:25:00 | Got to go back to basics. Take the motherboard out of the case. Place on some non-conductive material, e.g. the foam out of the box. Install RAM and cpu. Make sure CPU ran pluged into correct socket (read instructions. Take PSU out of case. Plug in the MB connector. You don't need to plug anything else in at this stage. Switch the PSU on (best check the voltage selector on the back of it - should be set to 220-240 volts). As it is an ATX device you will now need to short out or bridge the power on switch. Again, see the manual for which pins these are. Just use a small screwdriver to link the two for a moment. If nothing starts up, i.e. the fans don't start to spin, then your MB is dead for all intents and purposes. Take it back and ask for a refund or another board. Not a good idea to go shorting out pins if you are not sure which is which. Puffs of black smoke and pretty lights can occur !! Best of luck. Crunn |

| 101796 | 2002-11-27 05:31:00 | Sorry, should have gone on a little longer. If she powers up at this stage. Back into the case making sure it fits snugly, nothing forced. Connect as before, i.e. as when out of the case. Retry power on. If functioning, plug your video card (sorry you probably have onboard video) in and monitor, keyboard (having turned OFF the power and for good luck pulled the plug out of the wall. ATX MB's have the power on to the MB unless physically turned off. Pulling out or plugging in cards can be a total disaster. If your machine continues to boot add more cards. Eventually you will have all the cards/plugs in. Similarly connect all the cables one at a time. This is all a bit tedious but I think you get the general trouble shooting idea. Crunn |

| 101797 | 2002-11-28 03:03:00 | You shouldn't have to be struggling like this. ;-) It's possibly a faulty board. Before getting too experimental, ask the shop ... they will almost certainly be happy to check it for you. However, Wake On Lan(Wake On Network) and Wake On Ring(Wake On Modem) allow for the power tro be turned on if the modem gets a call, or a special packet is sent on a network (usually so administartors can remotely update software when everyone else is at home, and might have turned the computers off). The 3 pin connector has 5V, gnd and WOL or WOR pins, in that order. WOR (and the power "switch" on a separate pair of pins) use a negative pulse (from "floating" or +5V) to ground. WOL sometimes uses a positive pulse (from ground to +5V). |

| 101798 | 2002-11-28 06:28:00 | You can check an ATX power supply (be very careful here) plug in m/b and hard drive only to give enough current to switch on full power short out pins 14 & 15 to bypass wake up signal you should see the fans turn on if not suppect power supply. Trev |
