PC not working after accidentally touching the fan

[dilaoquino]

Hi, im just an ordinary teenager who needs some tech help. I have a regular computer and I have a problem. I need my computer because there are files that I need.

So heres the story...
It was just a regular day. I was playing some games in my computer, then suddenly I accidentally pushed some wires (color yellow and black) to the fan then the monitor just showed red stuff. I couldn’t shut down the pc by clicking the power button so I unplugged the power cable. I put it back and when it didn’t display anything in the monitor. I didn’t know why. I checked the mouse and it has a light, i checked the cpu and the light in the motherboard was still on and the fan was running perfectly. So I unplugged the power cable and everything else so I could clean the CPU. After cleaning the fan, the RAM and some other stuff, it still doesn’t work. So I searched stuff in the internet on how to fix it but I didn’t understand most of the things they said. I really need my computer right now : /

there is nothing wrong touching the FAN while system running
but you touched the wires unless there is some sorting in MB PCB
check your display card or
remove the ram if its beeping or not
