Hi guys my computer was working fine for 3 months then my brother was playing around with me and pushed me out of my chair computer chair while i was wearing my usb mic. the chord from my mic pushed the desktop over a lot and it almost fell off of my desk.. So then i turned my desktop on and everything was fine on my moniter then all 5 minutes of the computer being on i was playing call of duty 4 my moniter shuts off i tried to turn it back on but it says no signal..

I tried clearing cmos
I plugged in the moniter to my labtop and it was fine
I plugged in my moniter, tower to another room still no signal..
