Boot loop after exiting the bios

[fletcheyp]

Bios runs well, detects my CPU and memory and temperatures are normal when I save and exit and load my bootable USB for Windows the windows logo shows for 5 seconds then the display goes black and it shows the motherboard logo again without powering down.

 

I have tried booting with a Linux cd but the same thing happened 

I have tried reseating memory to each slot and with new memory

I have tried with another graphics card 

I have tried with a different power supply

I have tried a new motherboard

 

When I short the power pins the CPU, VGA, DRAM and boot led turn on then off one at a time when the motherboard logo shows up they all turn off

While in the bios only the boot LED is on

 

Specs:

Ryzen 5 3600 (stock cooler for now but temps are fine)

Gigabyte B450 aorus elite 

(Bios ver. F51)

Asus strix GeForce gtx 1080ti

2x8GB hyperX fury ddr4 2133MHz

EVGA supernova 750 G2 80plus gold

 

Thanks for your advice

Head into BIOS, do a "load optimised defaults" then set CSM to disabled and leave everything else as is. Does it still reboot?
