New motherboard help needed

Vejovis

In serious need of some techie help.

I have bought a new motherboard for my son. We've swapped everything over, but nothing is happening when we try and turn it on, all we are getting is a green light on the motherboard. The fans aren't starting or anything, just absolute silence.

I've downloaded the motherboard manual and checked the pin set up is correct, which it is.

Any ideas where to go from here?

We need makes and models of what you've got. Below is an example of what to list:

Motherboard
Processor
Memory
Power supply
Graphic card
Soundcard
Case
Harddrive/s
SSD drives/s
Optical drive/s
CPU cooling

as above (more details req) however a green light on the board shows there is power going to it,


the obvious suggestions are , where the power is plugged to the board , is there a separate 4 pin power connector , you have forgotten about?


secondly please double check the pins going to the power button connections on the board , are they on the correct ones,


anyway reply with the system info

There's only an 8 pin plug on the motherboard, but there is a 6 pin power connector and a 4 pin power connector. Should we be using the 4 pin and ignoring the 6 pin?

please tell us the mother board model ,


different boards different ways ,


there is a dirty big plug on the motherboard that the big plug on the PSU goes to , is there ALSO a 4 pin plug and a 4 pin socket on the motherboard , passably close to the CPU

look in the bottom of the box for a 4 pin to 8 pin adaptor

It was a refurbished board, so there was nothing else with it. Would I be able to buy one from a computer hardware shop, or are they specific to each board?

I'm using this picture, for your reference.

On the top right, there is an 4+4 pin plug, labelled JPWR2. Do you have a 4 pin or 8 pin cable plugged into this from your power supply? 8 pin is best, but 4 pin does work.

On the bottom, underneath the memory slots, there is another 20+4 pin plug labelled JPWR1. Do you have a 24 pin ATX connector plugged into this, or are there 4 pin remaining?

Pretty much all of today's PSUs will come with 20+4 pin ATX connectors and an 4+4 pin ATX plugs. You can get away with using 20 pin ATX connectors, but it's not really ideal. Usually the plugs are split, that's why I said 20+4 pin and 4+4 pin - they are usually pretty close togther, but split into 20+4 plugs and 4+4 plugs together.

Something I would strongly recommend is to examine the pins on the processor socket. I don't know if you've taken it in and out the socket when swapping, but if you have then make it a priority to check.

Take the memory out and push it back in again firmly. Don't be afraid to apply a little extra pressure to be double sure. Also, make sure the lugs holding the memory are clipped in properly.

One last thing I'd do, is just take everything out and test it on a table. Just hae the PSU, keyboard and graphic card plugged into the motherboard. But I'd be looking at connectors then CPU and memory as a priority.

Just before you do take everything out, I forgot to suggest reseating your graphic card. The new case might make it sit slightly differently in the motherboard.
