PC does not boot after pressing power on button

[silverrealm]

Just finished building my PC and it successfully POST for the first time. So i switched it off by holding the power button and prepped my USB stick to install Windows, however, this time it does not start after i press the power button. I tried resetting CMOS and checked all cable connections to no avail.

- Clear CMOS and try again.
- If you have other GPU do try.

Just a tip instead of pressing down the power button to switch it off.
You can use Windows USB install, under repair your PC there is a option to turn off the PC properly.

If still cannot, if you buy from SLS shops you can go back there for troubleshooting.

Try shorting the power button pins on the motherboard, see if that works. I see Tecware case I scared already after the previous guy kena a faulty power button on a new Tecware case.
