I recently used an air duster can to clean my computer, and now it won't display anything on my monitor. The PC lights are on, and all the fans are running normally, but there's no signal. I took precautions while cleaning, but my air duster did spray some liquid when I held it upright. Does anyone know what could be causing this issue?

Make sure your monitor is connected to the right port. Sometimes it can be easy to overlook during a cleanup.

ConnectMaster: Yep, I verified that it's plugged into the correct port.

Try turning off your computer, removing the RAM, and cleaning the pins with rubber. After that, plug them back in and power it on. Sometimes dust can cause issues with connections.

DustFreeZone: I already did that, but it didn't help. I'm still stuck with no signal.
