New Ryzen 7600X/Mobo/RAM combo not booting

[Rothingham]

Hey, 

 

I got a new mobo/cpu/ram. 

Asus TUF Gaming B650-PLUS

Ryzen 5 7600X

2x16GB Kingston ValueRAM KVR48U40BS8K2-32 

 

But when I installed everything I got some LED warnings on the mobo. And it's not going into bios. 

 

Video with LEDs

 

The LEDs are:

CPU

DRAM

VGA

BOOT

First DRAM and CPU are lit for a second.

Then VGA stays on for 20 seconds.

After that the system reboots and it starts all over. 

Nothing is shown on my screen (obviously).

 

I reseated every component (cpu, ram, gpu) and connector. 

I took out the cmos, turned off power, waited a while. 

I tried with the cmos of my old motherboard.

I tried running it without my GPU, using the iGPU.

Nothing helps so far

 

Fyi this is paired with (which was working before) 

Asus GTX 1080 

Corsair H100i AIO 

Corsair CX650M

 

My old cpu/... were an i7 3960x/asus p9x79 pro/24GB DDR3

 

Any help/advice is greatly appreciated.

Solved. 

 

I just had to update the bios using the USB Flashback . 

 

After that everything worked fine.
