[QUOTE="chscag, post: 1228483, member: 46727"] You did an upgrade rather than a clean install. That almost always results in fragmentation which will cause slow downs. Here's what you need to do: First, buy an external drive. Use Time Machine to make a full backup of everything. Make sure it's a good backup. Then boot with your Snow Leopard DVD. Use Disk Utility to wipe the drive clean, and then reinstall Snow Leopard. During the reinstall, it will ask if you have a backup from which to restore. Respond yes, make sure the external drive is attached. The backup you made will be restored automatically and all the fragmentation will be gone. The system should then boot faster. After the backup is restored, it's a good idea to also do a PRAM - NVRAM reset. See the following Apple KB article: [URL="http://support.apple.com/kb/HT1379"]LINK[/URL] [/QUOTE]
