Power

By nu4ever ·
I have a computer that when I go to turn it on it won't. At first I thought it was the power supply. I changed power supply and it still wouldn't boot up. Then I thought maybe I would check the motherboard connectings. When I opened it up I found one of the red and white connects that said power on it and it wasn't connected. Well I wasn't sure where it connected so I looked up the motherboard and couldn't find the specs. It is a intel motherboard with an 810 chipset with FW82810E on the chipset. Well I found what I think might be the specs and put the power connector where it might go on the mother board. To make things simple it still won't start. The only thing I can think that it might be is the power switch. Any ideas?

The 810 chip-set is for Celeron and PIII CPUs.

These usually did NOT have the axillary power connector.

Is this a "new" system?
Or one that stopped working 1 day?

For a new system:
Check and verify ALL connections.
Don't guess. If you cannot identify a connector ask us.

Check the position of the CMOS reset jumper.
Motherboards often ship with the jumper set to reset. In the reset position, most boards will not boot.

You can test an ATX power switch with an ohm-meter.
The 2 wires on the connector should read open with the switch just setting there.
When you press the button, the reading should be close to zero ohms.

If this was a working system that just stopped one day:
Remove any modem and NIC cards.

Check the motherboard for any sign of a burnt discolored or bulged component.

Try resetting the CMOS memory and see if it will now boot.

Chas this is an older system that we have used in the past. On Friday we moved the computer and on Monday when they tried to start it, it wouldn't start. I checked all the connections from the power supply and they all looked fine. I've been certified in A+ but am not sure where the cmos jumper reset is. As for removing the modem or NIC card if it boots up later do I reinstall them? Some the ideas you are giving me are new. With the ohm-meter I'm not sure where to put it. How do I reset the CMOS memory (do I just remove the battery) if so I did that already?

Do the lights come on but it fails to boot up? Or do you get absolutely nothing, no lights, no fans, nothing?

If you get lights and fans, but no boot up, try re-seating the video card, particularly if it is an AGP card. If you have moved the machine, there is a possibility that this card has moved in its slot enough to cause a problem, and the problem is usually that the thing won't boot. AGP cards are like that.

If the red and white twisted wires were unconnected, then lets make sure you have them back in the right place before we look for trouble elsewhere. On your MB there is a front panel connector with 16 pins sticking up from it. There should be other colored twisted wires plugged in to some of the pins. The pins you want for the red and white wires are #6 and #8. These are the third and fourth pins from the end along the side that is toward the front of the computer case. Also be sure that everything is tightened in it's own slot after moving. It must have gotten bounced around quite a bit for those wires to have come off.
