I built my PC (i7 13700K on ASRock Z790 PG Lighting D4) in december 22 and it worked fine since then. Around two weeks ago Iwanted to wake my pc from standby and it didn't wake up. I then completely powered off the system but it didn't turn on at all anymore. When pressing the power button, absolutely nothing happened.
So I began swapping and removing components (incl. PSU) and in the end the only thing that made a difference was pulling the CPU power connectors. Doing that, the PSU turned on and the fans started spinning but nothing else of course. CMOS battery was above 3v but I swapped it anyway. Resetting CMOS also made no difference.
So I tried two other mainboards from a different brand which made the PSU power on and the fans spinning up upon turning it on but nothing else. So no POST, no PC-speaker beeps, no nothing.
Now for my understanding it clearly had to be the CPU as it was the only component left that I didn't swap.So I made an RMA for the CPU and today I received the replacement.
Guess what... Same problem.
I'm really desperate bc the only theory that would make sense to me right now is that the mainboard is damaged in a way that it also kills CPUs and i'm really afraid the brand new replacement CPU has just been bricked.
Can that even be possible and if yes, can the mainboard manufacturer be made responsible for the damaged CPUs?
Any help would be greatly appreciated!
