Motherboard problems are rare. Likely problem areas are memory, video graphics, cpu fan, cpu pins, etc.
Look for disconnected or loose cables and connectors. Remove and reseat everything.
Likely you have pierced the memory with a bit of static electricity... so test your memory modules one at a time...
