My desktop icons recently somehow became all squashed together. How do I make them normal again?

Question

My Icons are the usual size, but now they are clumped close together and overlapping. I have tried the usual re-arranging and whatnot but am unable to fix it.

This is in Windows Vista, don't tell me to switch OS.

Answer 1

Right click desktop -> sort icons -> by type

Answer 2

right click> align to grid / auto arrange
