I posted a few months back about how my brightness controls had randomly disappeared. And yes, I did everything possible to make them come back (resets/reassigning to other keys/etc.) and nothing worked. Eventually my macbook started taking forever to restart like 5+ minutes. So, I decided to run disk utility repair to see if there were any issues. There came up a few errors, which I looked up and the majority of forums mentioned the only way to fix the errors were to completely wipe and re-install. I chose the Zero-Data option and reinstalled. My brightness controls button came back and my computer was restarting faster than ever. I ran disk utility again and there were no errors. I then saw that there was a software update from my 10.5.5 to 10.5.8. I completely the software update and was forced to restart. My laptop would not restart. It got stuck on the Apple logo repeatedly for 30+ minutes. I kept trying and I couldn't get past it, so I did another wipe and re-install and chose not to update. The computer was back to working beautifully again, but I ran the hardware test just to make sure everything else was okay. It came back perfectly. It's been a week since then and it's still been working great until tonight. Towards the end of working on a photoshop project tonight my computer started freezing with every small mouse movement. During the freezing, it made clicking noises. I exited out of photoshop and it was doing it with every single program. I couldn't even close my Mac Mail. 20 minutes later I can't access any other programs besides Firefox without my computer freezing with every movement and load. Firefox working is the only reason I can even type this. Firexfox is still amazingly fast, but everything else is messed up. Sorry really long rant, but there were a lot of details to explain. Any suggestions? Also, I've barely loaded anything back onto here yet since the wipe. I've used 17.5 GB and have 215.07GB available.
