Question PC turns on but nothing on the monitor.

[a failing gamer]

The pc worked for a year and a half, and now suddenly this is happening. The lights are working and the fans too.
The monitor is working, it just says it doesn't see any input.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please include your system's specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Case:
OS:

Maybe see if you can reseat the GPU, if the system is powered off of a discrete GPU. If the PC is a prebuilt, please state the SKU.

before you start taking things apart try a different monitor and cable , if a different monitor works then its obviously your graphics card thats got a fault.

I have 2 monitors, one connects with hdmi and another through DVI, disconnected both of them one at a time but still, they just don't see any input from the computer.
