When you restore power the system is likely performing a POST test. Since the fans are not turning back off and the system is unresponsive its likely the plant knocked something loose inside. If you are familiar with the insides of a computer, open the case and try re-seating the RAM. If that does not work go over every cable and make sure non of them have come loose.

3 fans turn on, but the power button does nothing
In addition to Sneakycyber's post above, if you mean that the monitor is dark and unresponsive, also check that the video cable is plugged in properly at the back. Unplug it, check that there are no bent/damaged pins on the plug, and re-plug again, If you have a separate video card installed in the case, remove it and re-seat it to make sure it didn't jiggle loose.

In addition to checking the internal and external connections, make sure that the heat sink and fan are still firmly connected to the CPU.
If you have another video card, or are using a GPU card now but have integrated video available, you could try swapping to that.
Are you not hearing any beep codes? I fixed a friend's HP computer once that had similar symptoms. Fans came on, but that was it, no beeps, nothing on the video output. Tried a new power supply, swapped the CPU, but turned out that he needed a new motherboard. On examination found that several capacitors on the motherboard were swollen and leaking. Searched on eBay and found a refurb board for his HP model.
Here is a beep code reference guide: https://www.computerhope.com/beep.htm

Good luck with the replacement!

I ended up trashing it.
The easy way out, unacceptable.
Go rescue it.
It can be a useful learning tool to learn how to troubleshoot and solve computer problems.
Nothing to lose and you might get it running or can salvage parts to perhaps use on another.
