Motherbaord won't start.

The power button having no effect typically indicates one of 2 things:

1. The Clear CMOS jumper/switch is in the clear position (or stuck button in boards like yours)
2. The power protection fail-safes have been triggered.

If the fail-safes have been triggered it is typically because of a short somewhere or an improperly installed CPU. Remove the CPU and make sure none of the pins are bent.

If that checks out the disconnect everything from the board except CPU, RAM, PSU and GPU. Make sure you are using the correct 8pin 12v power from the PSU, it is possible to accidentally connect a PCIe 8pin power with some PSUs where the connector is a bit softer and more flexible.

If you still have no joy then thoroughly examine the underside of the board for anything that could be shorting. The fact that you have power to the board (LEDs light up) but the power switch does nothing indicates a safety feature is preventing damage to the system should the board attempt to power on. It could be anything from a bent over component leg under the board (from a capacitor for example) that is shorting to a screw that fell on the board somewhere and got lodged in a place that created a short.

Good luck

If you need a multimeter to find the short then it's time to return the board What I have been talking about is the obvious, a component leg bent over and touching another component's leg etc. It should be visible to the naked eye. This kind of thing can happen when installing the motherboard into the case, scraping the underside against a standoff for example.

The general rule with this kind of situation is to disconnect everything from the board, check it over thoroughly and then start troubleshooting from there.

On the off chance we can find the issue, lets go through some troubleshooting steps:

1. Take the board out of the case and remove everything from it (CPU, GPU, RAM etc)
2. Examine the board on the back side closely, look for any sign of scraping or bent component legs that may be shorting. If you see none move on.
3. Install the CPU and the 24pin power connector, nothing else. See if the power button responds. If the system powers on in this state it will not post but at least you will know if the power on function is working.
4. If the system powers up in step 3 insert a single RAM module in slot A2 and connect the 8pin CPU power connector (it should be a 4+4 connector, not a 6+2). See if the system powers on.
5. If step 4 is successful install your GPU and power on.
6. If all goes well you should be able to post at this point.

If you fail before step 4, return the board to your place of purchase. Warranty should be covered by the retailer.

If you fail after step 4 post back here and we will dig deeper.

Good luck

Well this might be another problem. While doing some research it turns out that this motherboard does not support my current OS which is Win 7 64-bit but it does support Win 10 64-bit.

It would be worth trying another PSU. Spec wise that one should be fine but if it has a fault, it could cause your issues.

Ok so I got everything working aside from the fact that I need Windows 10. I looked at the Windows 7 USB patcher but that would really only work if I was going to install 7 but I've already got it installed.
