I just finished cleaning my PC, but now it won't display anything when I try to turn it on. I've already attempted switching it off and on again, and I've also changed the HDMI cable. What else can I do?

First off, can you tell us how you went about cleaning it? Any details help!
Double-check that the HDMI cable is connected to the GPU, not just the motherboard. It's an easy mistake to make!
I mean, I cleaned it, not built it from scratch!
Be cautious about the cleaning methods! If you used a cloth, that might have caused electrostatic discharge, which can fry components. Ideally, only compressed air should be used.
It's essential to check all your connections. Make sure the GPU is fully seated in its PCI slot and that all cables to the CPU, motherboard, and GPU are securely connected. Also, you could try toggling the switch on the power supply before turning the PC back on.
I checked everything, but only the fans are spinning and neither my mouse nor keyboard turns on.

I just wiped down the fans and the GPU.
