my finder doesn't work... the desktop appears blank!

hi, i'm very desperate: please help if you can
i have MacBookPro 15" intel core duo 2.16 GHz/1.2f10...

today i started my mac and the desktop appeared blank, nothing on it!!!

every one second the screen flickers, the finder shows up (with all my files on it) and i can't select anything at all, and it hides itself again:
finder on, finder off
what can be wrong with the FINDER???
when using Force Quit the FINDER shows on and off, if i'm quick i can force quit but nothing happens...
does anybody knows what to do?
i just looked for software update and nothing appears.
can you help?

sorry for doubleposting

sorry for doubleposting, but i don't know if it's a macbookpro problem or OS X ? i'm new to the forum and really can't find online any resemblance with what is happening with my mac. can you help?

What did you update?

you probably shouldnt post your system profile on the net.

your mac address, IP address and computer serial number are in there

software update

When did your MBP start behaving like this? What happened between the time it was fine and it went berserk? Did you install any software or updates? Did add peripherals?

When did you buy this MacBook Pro? If it is still under warranty, I would take it back to the Apple Store or give Apple Care a call.
