I'm really not sure what to do here... A few days ago my 2011 MBP has started doing some really strange things. I probably really screwed something up trying to speed up my computer because it was going slow. I tinkertool and onyx hoping I could figure out why my computer kept getting the pinwheel, and I seem to have made it worse. I didn't do anything drastic, or so I thought, just some general clean-up procedures. I'm not sure if it's even related. Here is what it has done so far: -when I bring up spaces, it freezes often for about 45 seconds. -system preferences quits after making any adjustment to a dispaly. -I got a "your computer needs to be shut down" message at one point. -I did some research and found something about front row being the cause of the display preferences issue, and as soon as I opened it my computer froze completely. I didn't even know I had front row at this point. -my primary display is not saved when I restart, it keeps switching back to my laptop screen instead of my external monitor. -disk utility repairs a bunch of java stuff every time i repair permissions... supposedly. no matter how many times I run it, it always "repairs" the same thing. I think that's it. I would reinstall, but I'm worried my computer won't be the same; I have a lot of songs and plugins, etc. that I can't imagine trying to install again, especially since I lost the box that had most of those discs. I'm also running SL on a computer that came with lion, so my install disc won't work. I'm stumped here. I'm afraid to do much else for fear of making it worse. I would hate to have to start all over again. By the way, this is a 2011 MBP, 10.6.8, 8 GB ram, and 750gb hitatchi HD (all brand new). I have a carbon copy clone as well as a time machine backup, however the CCC was done soon after I started noticing issues, and I'm not so sure about the quality of the time machine backup either. Any help would be greatly appreciated.
