Delete Recycle bin when it freezes the computer.

Sorry for the long title. My co worker asked me to fix her computer because it wasn't working. when i looked at it i noticed her recycle bin has so much in it that when you do anything with it the computer freezes.

She told me she was unable to find her recycle bin but always threw things out. I knew how to find it and when i did it just froze the computer.

So I am stumped on this one, any tips?

If that is not the solution try to fix the bin, it may be corrupted
