Mac Book Problems Need Help

Have you dropped your computer or otherwise bumped it hard enough to knock something up? It could also be that during manufacturing a cable wasn't completely connected and has finally come loose. Probably most likely case is that your iSight just crapped out. (it could also be that your iSight hates looking at you) If it is under warranty, just see if you can't get it fixed. One last suggestion, if you have a friend with a macbook, you can always do a quick swap of hard drives and boot off his/her drive and see if there is just some kind of software error. (that would definitely point it out) hope this helps!

 

this has happened to mine before. Try restarting your computer.
