osx finder

[spirit]

mine keeps crashing.. i think its finder, it happens when i browse files on my hd or even when i empty the trash, its completely random though... im a bit of a beginner when it comes to all things mac - is there a way to find out why this is happening and how do i fix it? i suppose its not too bad as it always recovers and reopens but it is a bit annoying..

its a macbook with osx 10..

cheers for any help/advice

yeah it just disappears all the icons on desktop disappear too, then a few seconds later, it opens another window and all the icons reappear, the taskbar thing at bottom goes too...
