Hello Everyone. I assembled a new computer with the following components. MBO of Asus Prime B550m GPU ASUS TUF Gaming RTX 3070 8GB CPU Ryzen 7 5800X MEM Kingston Fury 2x8 gb 3200. the problem is the following, when I press the power button, the cpu fan and the gpu fan turn on, but after 3 seconds the PC turns off. I tried with one 8 GB memory on all Mem slots, the same problem. I noticed that when I don't put the memory in the PC it works but there is nothing on the screen. When I insert the memory and disconnect the 8 pin MBO power cable, it works the same but there is no image on the screen. the processor is probably working because I can feel it heating up to the touch. The power supply is Thermallake 750W. I assume that it is a problem with the BIOS. Maybe some suggestion what else I should look at?
