101784 2002-11-27 01:36:00 one other small thing. did you have a heatsink on cpu when u first tried to fire it up?? what heatsink paste have you got on it? tweak'e (174)
101785 2002-11-27 01:37:00 I have seen similar things before, it could be a faulty on/off power switch, try removing the switch and shorting the power pins on the Mainboard with a flathead screwdriver.


Cheers

101786 2002-11-27 02:02:00 No power supply expects a "power OK" signal. No motherboards produce a Power OK signal. Power supplies supply (;-)) a power OK signal, which the motherboards use.

Suspect your power switch.

101787 2002-11-27 02:05:00 Sorry Graham...my post does read the wrong way round.

I had this trouble in the mid 80's with a PC, where to power supply had no pwr_good signal. A reset after power up worked though.

101788 2002-11-27 02:06:00 Already checked the power switch, and tried manually shorting the jumpers, didn't work.

The hsf is a standard AMD issue one that came with the CPU. It has generic thermal gum stuff on the bottom, and no, I was not silly enough to try to power it up without the HSF attached, although thankyou for trying to help me solve the prob.

I am taking the whole machine round to a friends tonight. while there, i'll be able to try a different cpu, ram, psu, video card and keyboard/mouse if necessary, so I should be able to find the culprit. Ho hum...

101789 2002-11-27 02:38:00 Perhaps start without even a CPU . See if you can get the fans turning . If a CD is connected (just the power cable), you should be able to open and close the slide .

Just be systematic, and DON"T PANIC !!!!! It's usually something stupid .

101791 2002-11-27 02:57:00 Would running a CPU on a faulty MB screw the CPU if the MBoard just wouldnt power up (Not related to the problem here - just a random Q.).

101792 2002-11-27 02:59:00 in reply t to Graham:

No, I cant get power to anything - I have tried plugging in a standard 12V computer fan into one of the HDD 12V connectors, which doesn't work. The only sign of life from the whole machine is that mysterious little LAN connector light. Makes me wonder if there is something fishy going on with Wake on Lan or something...

101793 2002-11-27 03:06:00 If the ethernet light is on, you've got it partly working . That's the 5V standby supply, which is on all the time . It feeds WAN devices, such as a NIC . What happens when you short the WAN connection to the motherboard? That should power up the mother board . (That is the same as the power switch . . . it uses a "momentary contact" for on/off .

(Have you tried tweak'e 's suggestion of "reset"?) .
