Think I might have fried my PC

Hello. Today I decided to try to clean my pc. I cleaned the fans and case thoroughly and vacuumed the fans also. The PC was unplugged at the time. However, when I did this I smelled some kind of burning from the PC, it might have been a coincidence but I’m not sure. When I first plugged it in, my monitor wouldn’t pick up the HDMI signal, and said “cable not connected”, no matter which cable I use (However, I have had issues with this in the past. It may be an issue with the graphics card) so I cannot reach the BIOS. The Ethernet port no longer lights up when plugged in, even when trying 2 different cables. The power button no longer shuts down the PC, even if I hold it down for a long time. The fans just slow down and immediately start again when I remove my finger
I don’t know what to do. I’ll try disconnecting the GPU and using integrated graphics, but I don’t have high hopes. Please help.

My PC specs are:
Ryzen 5 2400g
RX 5700
16 GB RAM

Should I vacuum my PC?

I know it seems the easy option, but you really shouldn't.

Yes you may have just fried the computer.

What part of it would be fried? Just one part or the whole thing?
