Hi,
I don't post in these forums that often since most of the computers I have are vintage Apple/Macintoshes. But out of my six computers, one of them is a Soyo PC running Windows XP whose age I'd estimate to be between 5 and 10 years old. (It has a floppy drive, so it can't be too recent.)
The other day I took out the Soyo PC's motherboard to dust the thing out and record its capacitors. (Since I'm planning eventual capacitor replacement, I thought I'd record them so that I can start getting replacements.)
Obviously, I had to unplug everything first (and remove the power supply) so I did so. The power supply wires are easy to remember, but there are wires on the motherboard that aren't quite as easy to remember.
I'm talking about two columns of pins in the lower right-hand corner of the board (assuming it's in its place and orientation inside the PC) and these pins had several individual wires (tied together in a bunch) labeled 'POWER SW, RESET SW, HDD LED, SPEAKER.' These wires have either two, three, or four holes in them. When I put the logic board back in, after I finished recording it, I couldn't remember exactly how the various wires were positioned, so I guessed. I turned on the power--nothing happened. So I opened the PC, took all the wires out, and only inserted the one labeled POWER SW. After several guesses on its position in the two columns of pins, I finally found the right orientation and the PC booted.
But when I tried guessing on the other wires' positions, I get a freeze-up and the power supply starts issuing clicking noises growing gradually in intensity. Of course, at this point I cut the power.
So I tried opening our family PC (a Compaq) to see how its wires were positioned, so I could copy the orientation into my Soyo. Unfortunately, all wires shared the same connector, rather than individual ones. I guess my Soyo PC is too old to be similar to my Compaq. (Or else the companies are different; that may impact it too.)
Does anyone know how these wires are correctly positioned in the two rows of pins?
I'd greatly appreciate any help on this matter,
