Which component is faulty: the motherboard or the CPU?
Hey everyone, just upgraded my CPU to a Ryzen 7 7800X3D. I also got new RAM (Corsair Vengeance DDR5 2x16) and a motherboard (ASRock A620M Pro RS). Since I was replacing an i7 with DDR3 memory, everything should work smoothly. But when I assembled it, I didn’t see any power up. The only thing that activates is the RGB lighting on the motherboard, which stays on as long as the 24-pin connector is connected. Fans, CPU cooler, power supply, and GPU fans are all off. There are no sounds or error lights coming up, even though the board has a few indicator LEDs.
What I’ve tried so far:
- The graphics card (4060Ti 16GB) and power supply (Corsair CX750) function properly with the old components.
- The CPU was seated correctly.
- I powered it without the graphics card connected.
- After that, I restarted and ordered new RAM sticks, testing one at a time. Checked the manual for socket compatibility.
- I shorted the power pins on the front panel; the power button still works on the old board.
- I tried fitting the CPU cooler into the other cooler slot—it worked fine with the old board.
- The GPU is connected and running.
This seems like a dead CPU or motherboard to me. Personally, I’m leaning toward these last two options but open to suggestions. I don’t have any other AM4 sockets or boards to test, so I’d appreciate another opinion before deciding to return one or the other.
Thanks in advance!

Is the Wi-Fi configuration the issue or the Wi-Fi itself? You may need to update the BIOS, ensuring you follow the proper installation steps carefully.
Sorry to hear that. As a final option, I ran it once more outside the case, and it worked. I think the issue might have been from using too many MBs, which caused a short circuit. Thanks for the update!
