Hi Allen, Yes, an Erase & Install of Snow Leopard would be very sensible, there are problems on your current system, most possible brought over from previous upgrades. As I have mentioned before on WAMUG, left over "Clutter" from previous systems can slow your Mac down and also cause problems. Over time, your disk accumulates obsolete, extraneous, or otherwise useless files, often called “cruft”—hacker slang for digital detritus. Removing cruft increases the disk space available for the system and reduces the chance of software conflicts. I erased my Hard Drive and did a 'Clean Install' of Lion, and have not experienced any problems in Lion or now Mountain Lion (which I did just an upgrade install).
A clean system installation brings the system software back to the standard configuration. This is necessary when system software is unusable or has been modified, preventing a normal installation. It is also useful as a final step in troubleshooting. Options to "Erase and Install" and "Archive and Install" are no longer present in the Mac OS X 10.6 installer. This was done for convenience, so that users do not accidentally erase and install their Mac OS X 10.5 Leopard partitions. However, "Erase and Install" remains available through Disk Utility, which is also included on the installation DVD. After you select your language and click the right arrow, an "Install Mac OS X" screen, this is where you diverge from Apple's standard upgrade script and erase your disk. Choose Utilities > Disk Utility. I would also "Repair the Drive" also before installing SL. If you need details how to preform the Erase and then installation of SL, post back. Point 1: Your TM backups and any other current backups will contain whatever is causing your problems. So you will have to be careful what you 'bring across from any backup'. First just bring across essential Data. Also installing any applications you require from the backup is much safer than dragging the applications across to a clean install. Point 2: After the erase and install of SL, download the Snow Leopard 10.6.8 Combo. Snow Leopard 10.6.8: <http://support.apple.com/kb/DL1399> (Note: there's a separate Snow Leopard 10.6.8 Supplemental Update: <http://support.apple.com/kb/DL1429> that is not included in the 10.6.8 "combo".)
