Basically for a while, my video cable has had a DVI adapator to connect my screen to my nvidia graphics card in my computer tower. I was on the train 2 days ago, and my suitcase flew off the luggage rack and the front of the tower cracked. Obviously when I got up to where I was staying I plugged in the screen, and the tower and the screen isn't recieving a signal anymore. I opened up the comp, checked everything even took out the graphics card and checked it, nothing is loose/broken. The cable was acting up before I left, I have sent off for a new adapter AND cable, I am just wondering could it be something else? Like something damaged at the front of the tower? Thanks!
