I upgraded my laptop to snow leopard and ever since it constantly freezes for about a minute or two at a time and this happens about once every 20 minutes i'd say. I've tried decreasing the number of apps that start on start up, looked everything up to make sure it's compatible (which it is), i've tried resetting the PRAM and the NVRAM and i've installed the 10.6.2 update. Still with no luck, i'm planning to reformat, but I have a few questions. 1. How do i reformat? I have a windows partition that i want to get rid of and i want to wipe all files off the system too, completely fresh clean start. Is there a guide to it? Also, i started with leopard on this laptop, will i need to use the leopard disk to install next time? 2. How long will reformatting take? 3. I use time machine to back my laptop's files up onto an external drive. I want to make sure iPhoto will have the same library when i start again (ie. face recognition is still applied to all photos, albums are still there, events are still there and most importantly, all photos are still there). How do i go about doing this? 4. I have photoshop and final cut pro installed but i don't know where the disks for these are. Would i be able to just copy the backed up app files of these across to the new system and would they just work there? Similarly, candybar will need to be moved across. Can i just drag that across too?
