2 options:

1) faulty vga card
2) faulty monitor

Try the monitor on another machine, if that works, then there's something wrong with your hw.
I also assume you checked the vga cable that goes from the monitor to the pc...

If the Geforce card is removable, you could try removing and reseating it. It may have worked loose over time.

Your monitor probably just died, why did you take your pc all apart ?

When I was phone tech support, we often recommended reSeating cards, memory, etc. before replacing anything. And, we recommended using another monitor or keyboard or mouse etc -- depending upon what the customer had on hand, or had easy access to. Obviously, this reSeating needs to be done with the big red [or black] computer switch on Off. If using PS/2 keyboard and/or mouse, PC must be off during reSeating.

I would surely hope the computer was off and unplugged before working on it.

yes the pc was off and everything was unpluged i took the pc on my bed and just take my graphics card out clean the dust and put it in back now my keyboard and mouse are not working oh and when i put vga cable to notebook its still just black maybe its graphics card but keyboard and mouse are not working idk what have i done

Take the monitor to shop and have them test it for you.
