What's wrong with my computer?

I have a sony vaio that has worked great up until this weekend when I moved it. Everything was working fine until I moved it, now it will boot up but will not detect the monitor or anything else hooked up to it. I use a wireless keyboard and mouse that lights up when I hook it up to the usb port, but it is no longer lighting up which is why i don't think it's a problem with the monitor.. I've looked around and everything looks connected..
