I recently purchased a new motherboard and transferred all my components over. Unfortunately, it wasn't compatible, so I restored everything to the original one. My computer failed to start, with fans and lights flickering briefly before stopping. After several attempts, it finally worked when only the CPU was connected. However, connecting the monitor shows "no signal input." The keyboard works fine with lights on but not the mouse, even when plugged into the USB port on the keyboard. I've tried various setups: using another PC for the monitor, connecting cables to both motherboard and GPU ports, using a RAM stick, and checking all connections. My specs include an Intel i7700 CPU, an Asus GTX 1070 Ti GPU, a MSI H110 Pro VDX motherboard, Corsair Vengeance RGB Pro RAM, and a Corsair CX450 power supply.
