Hey guys, I have an iMac 17" 2.0Ghz w/ 1Gb Ram When Snow Leopard came out, I backed up via Time Machine and did a clean install, then restored via Time Machine Ive been having three main problems, among a few small ones. When I right click the dock, half the time it freezes, denying access to the dock or finder for a good minute or two. Also, front row puts tagged tv shows in the movie section, and catagorizes them as "various" in the tv show section. On top of all that, safari is acting up. Ok so I was planning on upgrading the ram to 3GB, the HD to 500GB, and do a fresh install of snow leopard. I'm assuming that time machine backs up all the system files and garbage that clogs up the system, so I'm planning on just dragging the files to a external hard drive, installing snow leopard on a brand new 500GB drive, then moving my files back. Will this fix my bugs? Or should I just install leopard instead? Btw leopard ran pretty slugish after a while, and sl did make my computer faster, but I assume the ram upgrade will keep leopard up to par. What should I do?
