Hello. I just recently received a MBP last week. 2.2 GHz, 160 GB 7200 rpm HDD, 15.4" inch, 2 GB RAM. I've come across a problem and I'll explain it very quickly. Basically I was in Photo Booth, I went to take a picture and the screen turned white for the flash. Then my screen went black. I could barely see anything. I decided to do a forced shutdown by holding the power button down. When I got back up, all my settings on my computer erased. (iChat, Address Book, Display settings, screensaver, iPhoto, iWorks, iTunes). Most files were still there (like my iTunes music), but they were no longer "associated" with their programs. I tried to re-import my iTunes library but that seems to have gotten corrupted during that "Photo Booth crash" thing that happened. Everything was a mess. After fiddling with it, I felt an erase and reinstall of everything was probably better with all my major files already backed up anyway. I erased and reinstalled and I haven't had a chance to set everything back up again but the computer is still crazy. If I have a saved setting like dock preferences or desktop background, it doesn't save when I restart. Sounds like I have a corrupted file in the Finder. But I erased and reinstalled everything. I do have Applecare and I did run TechTool Deluxe and no problems. It did find a problem with the Video RAM one time but I rescanned and it was fine, so I don't know. I'm not sure what to do. I don't want to set everything back up again and have this happen continually. Is something wrong with my computer? The Finder seems to be acting weird. It doesn't even show icons anymore for the "Movies" and "Pictures" section. Just pictures of folders. Something just feels wrong. Can I ask for a replacement? I'm not even sure what the problem is so I don't know what to say to Apple. Please help. I appreciate your time.
