I recently removed all the keycaps from my keyboard to clean it and reattached them while the keyboard was still connected to my PC and everything was powered off. Now, when I try to power up my computer, the fans and lights turn on, and there's a red light on the motherboard, but my displays, mouse, and keyboard aren't powering up at all. I've attempted power cycling, unplugging the power and holding the power button, switching the display cable to a different motherboard slot, swapping the RAM slots, and even removing the CMOS battery. Looking back, I realize I probably should've unplugged the keyboard, but I'm not sure if pressing or holding a specific key could have caused this issue. Any assistance would be greatly appreciated!

Just to clarify, were you powering the computer on while the keyboard was still connected during all those attempts? If so, try disconnecting the keyboard and then see if the computer powers on. If you have another keyboard, it might be worth testing that one as well. If it powers on and gives a "No keyboard is connected" message, that would mean the issue lies with the keyboard you cleaned. If it still doesn't power on, it might be a short circuit in another part of the PC.
Just a heads up—this problem of yours seems to be popping up frequently. If you check around, you might find similar posts with helpful answers. But if you haven’t got the info you need, keep at it here!
First off, try removing everything from the PC except for the power supply and the monitor. Sometimes, if there's a device causing a conflict, it can stop the computer from booting up correctly. Also, check if your motherboard has a BIOS POST beep when you start it up—if it does, that could give some clues about what’s wrong.
