Simple screensaver crashing

[Data_Dragon]

i am rather new to C#, i am switching from java, i followed through with a baisic c# screensaver tutorial, then i tried to add a picture and make it bounce around the screen. i added a picture box set to a picture(LM), i made a loop to make it move, then tried to figure out how to start it, i added it the end of load. this is probably extremely noobish and i am sorry,but if someone would help thatd be great
