Windows crashed making a backup, twice.

[BrokeIC]

I made a System Image backup (438 GB) from the Control Panel Backup program, and that was made OK. I then went on to make a backup. I went to bed last night thinking it was gonna spend all night making a backup. I woke up and found only 2.36 GB written and Windows rebooted by itself to the login screen. When I logged in, it said Windows had an unexpected shutdown.

So around 12 hours ago, I thought I'd start again. It says data file backup size is 313 GB, but Windows rebooted while I wasn't looking with an unexpected Windows shutdown error message. So I've waited 12 hours for this moment, and I don't know if it completed! I can hope it completed, or I can find out why it keeps crashing Windows, or I can just make an "Acronis True Image Home 11 with Plus Pack" backup on a different HDD because I'm wasting time with Win 7 backup.

Hi BrokeIC,
Usually backing up should be a breeze.

'Windows rebooted by itself to the login screen. Windows had an unexpected shutdown. Datafile backup size is 313 GB, but Windows rebooted while I wasn't looking with an unexpected Windows shutdown error message'.

Sorry to break the bad news to you .
You might have got hit by a rootkit or virus. Zeroaccess is the new hot stuff around that download more viruses for the infected system making backing up hell for the user(s).
Before backing up, run your AV to check for nasty stuff.
How do I know? I got hit when I was doing a routine inspection, Windows shutdown and rebooted.

'Acronis True Image Home 11 with Plus Pack" backup on a different HDD because I'm wasting time with Win 7 backup'. Backing up on another HDD is good idea but do run a scan after a successful back up just in case the nasty stuff got copied too.
