Hi everyone! For the first time I've come across a computer problem I have no idea how to solve. I am currently building a PC with an Intel G4560 (LGA 1151) processor and Asus B250 Mining Expert motherboard and Corsair ax 1600i PSU. Everytime I try to boot, the PSU fan and CPU fan start spinning, but shuts down after approx 3 sec. Then noting happens. I've changed every part of the system. This is the troubleshooting I've done so far:
  • Changed motherboard to Asrock h110 pro btc+ (same thing happens here).
  • Tried two other PSUs (Corsair RM 650x and Corsair RM1000x). These are confirmed to work in other computers.
  • Changed RAM
  • Reset CMOS (also taken out the battery)
  • Tried in total 3 box fresh CPUs (2x G4560 and 1x G4400) all failing to boot
  • Tried to put the CPUs in a computer I know work (motherboard ASUS ROG Maximus X Hero). Same thing happens here (no boot), but when I connect the Intel 9900K to this computer it boots as normal.
The computer shuts down before post beeps, so I get no message or error code to follow.

Can you help me with this problem? As I've said, this is the first time I've come across a problem like this, and have no solution.
