Your computer isn't transmitting any signal.
I previously owned a prebuilt gaming PC (Lenovo Legion). I recently upgraded my GPU and installed new RAM, but now the system won’t respond. I retained the old RAM and GPU. I’m trying to reinstall them, yet the machine is unresponsive. I suspect the motherboard might be damaged. Everything else seems normal—hard drives spin, fans run, and the GPU fan is active. Please advise if you can assist. Thank you!
