I have built a new PC and I'm having some trouble with booting into Windows.

The PC will post and I get a beep. The display then goes off when trying to load into windows. At this point I can not turn off the PC by the normal power switch, I have to use the PSU.

I can boot into the bios and if I boot from a usb to re install Windows I can get into Windows briefly before the screen goes off again and I'm back to where I started.

I have ''breadboard'' outside the case but the same thing happens.

I'm new to PC builds so any help would be greatly appreciated.

specs:
Gigabyte ab350 motherboard
Ryzen 5 1600, stock cooler
Palit Super Jetstream GTX 1080
2 x 8gb DDR4 Corsair Vengence
650w Corsair PSU
1tb Toshiba HDD

Try resetting BIOS. Unplug all cables. Remove the MoBo Battery,. Press and hold the power button for 20 sec.(to get out the rest of power)
Wait 5 min. Put the battery back in, Connect the cables. Restart

Thanks Lakken, but I'm afraid that hasn't worked.

I've followed the steps and reset the bios. On booting the PC it took a little longer to post and beep, but it did to it. Then the Windows icon came up before the screen went black, no signal. Then I could not turn off the PC via the power button and had to again use the PSU.
