Okay, so I have like a couple of problems, so I don't know if these actually belong here. Sound Volume Does Not Change After Sleep Mode This has been a problem of mine since last year. Every time I open the lid, waking up my Macbook, whenever I use the volume keys, the sound doesn't raise nor lower. Sometimes, if I unplug and replug my earphones, the sound can change again. Sometimes it doesn't. Boot Camp Cannot Find Macintosh HD Nor Change Brightness Levels When I feel like restarting from Boot Camp to Macintosh, normally I usually click on the little Boot Camp icon on the bottom right screen, but recently, it says that it cannot find the partition, which is odd considering that I can still restart to Mac OS X via OS selection screen (the one where you hold the alt/option button when your Mac boots up). I also can't change the brightness level. I think this all happened after I updated the graphics card (currently 307.83 - WHQL).
