Computers shut down immediately after Boot Up

Jun 29, 2010 5:40AM PDT

I have 2 computers the first is a home built desktop, the second an HP 2140 Net Book, both running Win 7 Home Premium. Last week they both started to behave strangely.
On start up, the desktop appears as normal, and then immediately Windows automatically closes down. There is no BSOD or anything like that. It just goes through a perfectly ordinary shutdown only halting to warn that it is waiting for background running programs to close.
As this is happening on both machines I guess it?s safe to rule out hardware failure.
I don?t recall installing any new programs recently, only regular MS Updates.
I?ve tried doing a system restore but always get the ?Failed to complete? error.
If I boot up in Safe Mode both machines work fine,
Can anyone offer any suggestions what may be the cause, and how I can fix it please?

removed Norton, then restored system to a time before the shutdown problem appeared, but this still hasn't sorted the problem. Do you, or any one else have any further suggestions? I really would like to avoid having to re format the drive and re install Windows.
Has any one else here encountered this problem recently?
Hope you can help!!

But I was guessing about Norton (and appear to have guessed right.) Your posts leave out so much detail that I can't guess what next. It could be anything so keep writing and see if anyone has new ideas.

PS. About Norton. Don't you find it odd they didn't warn you about that?

Just last week another incident with someone that tried one of those "Windows Activators." Nothing but trouble.

By un-installing and re-installing all 3rd party programs one at a time, I found that my machines don't like GFI Backup for some reason. I have completely removed the program and all is now well. I did re-install it again but the problem returned. As there are plenty of alternatives available, I don't think I'll try to find the reason it doesn't work for me.
Thanks to you all for your various suggestions.
