Restart on updates

[Net-Monkey]

My iMac 27" Mid 2010 restart every time when I'm trying to update any apps.
No matter from the app store or download the dmg, it restarts in the middle of the process, now I'm unable to update anything.
I've tried to reinstall the Mountain Lion but still doesn't work.
Please help
Thanks!

Clean install or did you import a TimeMachine backup?
Did you try a different clean User Account?

Do you have the original disks with 10.6, you could try to install on a USB stick and see what is there.

Did a few restore but still restarts every time I tried to update.
So I did a clean install, now it works!
Thanks!!
