Why is my computer not turning on and only shows a green light?

Well you can check out the following video: https://www.reddit.com/r/computers/comme...

Your computer shows only a green light but won’t turn on, it usually means it’s getting power but not completing the startup process. First, disconnect all peripherals and hold the power button for 10 seconds to drain residual power. Reconnect the power cable and try again. Check if the RAM, GPU, and power cables are properly seated inside. If it’s a laptop, remove the battery (if possible) and power on using only the charger. If the issue persists, the motherboard, PSU, or power button may be faulty—contact a technician for hardware inspection or replacement.
