Hi! I really don't know which category to place this problem in, but my pb has gotten really "slow". I've erased files, and there's 10gb of hard disk space left. I've upgraded my memory a few years back and it's now 768mb ram. I don't really do much with this computer except use safari, upload to flickr, edit photos on Photoshop on occasion, ms word. I don't even open my iPhoto anymore because the beachball always turns up and slows down the pb or it totally freezes. I don't know what to do. Should I reformat my computer? How do I go about this? Save all pertinent files/docs then reformat the OS? Please help! Or can someone point me to the right direction to go to. I'm totally clueless.
