Why does the computer restart on its own after replacing the motherboard?

Question

Computers

I bought a new motherboard, processor and power supply. When you start the system, the computer reboots by itself. Everything seems to be inserted where it should be. Of the old components, only RAM. What component could be causing this constant restart? The socket of the processor and the motherboard are the same

Answer 1

Good evening.
Let's try to help you.
There are several problems, all related to iron.
1. Somewhere there may be a bad contact. Disconnect and reconnect the connectors you can see in turn, especially the motherboard power.
Replug all connectors!
2. Sometimes the Reset button hangs.
The Reset button in the system unit can short out and cause a reboot. Disconnect it from the motherboard and check if the problem is solved. If, after disabling the button, everything will be "ok": disassemble the front panel of the system unit, clean the contacts of the Power button from dirt.
3. Problem with RAM. Replug it by rubbing the contacts with an eraser. Sometimes it helps. Perhaps the memory is not supported by the processor, this also needs to be checked (see the specifications for your CPU). You can try to stick the RAM in another slot.
