HT1338 imac OS X 10.6.8 won't install updates

Question

Every time I try to install software updates, it immediately goes to the "restart your computer now" message before any updates are installed, and it restarts immediately before any updates get installed. I've tried it a dozen times and nothing is changing. I can't access itunes store because of this (as far as I know).
Frustrating.

T Walsh,
Use your install disc, power up and push the disc in while holding the C key, after it loads select your language then on the next screen, in the menu bar select Utilities>disk utilities, when DU opens select (highlight) your volume in the left side bar and run Repair Permissions, then run repair disk.
Then quit eject disc and logout, power off.
Restart and login, run software update, and see if it does the installs, if not try, the following as there might be some corruption occurring, especially if you doing these via WI-FI.
Run the software up date, write down the available updates (application, version) Then you can try to do one at a time by clicking  the the box to install update, after it completes then run software update again doing the one at a time thing, till there are no more up dates.
You can also go to the Apple Supprt site and down load the updates 1 at a time with the stand alone installer (this is where the write down the update name and Version comes)
Open Safari, Safari Preferences, general tab, on "Save downloaded file to:" select Destop, if it is not in the dropdown, select other, then select Desktop from the left side bar.
After a download completes click on the installer package and follow the promtps.

In the search window in the upper right corner type in the name, version, update, it should direct you to the link.
Hope this helps
