If you've ruled out the monitor and vga cable it seems likely to be your GPU. Additional information would help us to help you. Your model and optional equipment and a description of whatever symptoms and or actions might have caused or contributed: for example whether you added or changed any hardware, drivers or other software, GPUs present etc. Something you can try if possible (depends on your hardware) is to try an HDMI cable. I once had the VGA fail but continued to work for years on HDMI.
