Thousands of files dumped on the desktop!

I was moving a bunch of files {a couple thousand} from one folder to another on my desktop and my finger slipped and dumped them on the desktop instead of the folder. Now my trackpad is frozen and I can't see any of the files. However if I connect a corded mouse I can move the curser and navigate. I can see the files when I go to the desktop folder but not on the desktop itself. I can't open any of those files that got dumped cause it says they are part of the system software. I tried reinstalling the running software but the drive ejects the disc. I hooked up the computer in target mode to another computer and tried that way but the target icon does'nt show up on the other computer. Any Ideas?
