I have found a Short Circuit in a PCB. Can I locate it with eagle?

There are two PCBs from a cheap fab and there's a short between +5V and ground on one of them, which I had noticed when using a multimeter to test. It's a large two-layer board which is visually inspected by me.But I haven't found the problem yet. I've ripped up all nets except for +5V and ground and hid all layers but the top and bottom copper, which at least lets me pay attention to the areas I need to examine. This helps a little.

If all the other things fails, connect a high current power supply between the +5 and ground, and see what lights up. You must do it in a dark room and shoot a video while you do it, so that you can record where the problem is, just in case you can not see by your eyes because of the quick speed. When you're finished the test, the short will be gone.This is the side benefit of this way.

Go into DRC menu. Examine parameters for any min clearances that are on the small side. Make the minimum clearances incrementally larger until you start getting errors when you run a DRC check.

If you have a current limited supply,and a thermal camera. You can run just enough current through there to make the short heat up. It's not necessary to pump a bunch of current in,and vaporize it, but just enough so that it heats up,and you can see the hot-spot with an IR camera or other equipment.
