Computer doesn't send any signal to peripherals after cleaning.

I just cleaned my computer by taking out all the fans and wiping the blades clean as well as removing the heatsink and PSU and cleaning those of dust. I reattached everything to where they originally were, (I never disconnected any wires, I only loosened the screws) and plugged in the peripherals and started up the computer. There was no signal to my monitor, my keyboard and speakers lit up as if the computer actually started up but never actually responded to any input from me, (caps lock, numlock, etc didn't light up) and there was no beep code, which I think is normal since I use an Asus mobo. I checked all the connections and nothing was lose, I've tested the system without the gpu, ram, optical, and hhd, and I received a beep code for no ram detected which seems normal. The q-code ends on 30, which is also normal, and all the fans work. Aside from all my peripherals receiving no signals, everything is fine aside for the fact that I don't know if my computer is even booting up since I can't see anything on my monitor. Any help would be appreciated! Thanks.

Mobo: Asus P8P67 Deluxe
Cpu: I don't remember the full specs, Its an Intel I7 2k series
Gpu: EVGA Geforce GTX970
Ram: G.skill Ripjaws X 8gb*2 DDR3-2400
Psu: Corsair HX750
HHD: Western Digital 1.0TB, about 5 years old, I know I should replace it.

Ps, I'm not the most experienced in computer hardware and terms.
