Computer Restarts When I Shutdown

What happens with shutdown in safe mode? Does it behave?

Okay, so then most likely it is a problem caused by a program running in your startup list.

You may have programs running at startup that is causing this issue. Please see this tutorial to temporary disable them and see if the issue is resolved:

I disabled everything (other than Microsoft services) and it still occurred. Although avast automatically started up even when i disabled it. I went back into msconfig and the only box ticked is avast.

Okay that is fine. Enable verbose messages to see where it is getting stuck:

Enable Verbose or Highly Detailed Status Messages In Windows 7 | 8


Please Run sfc /scan now using option 2 in this tutorial: SFC /SCANNOW Command - System File Checker

Please post back the results.
Please indicate what message was displayed at the end:

Windows found no integrity violations

OR

Corrupt files were found, and windows was unable to fix them.

OR

Corrupt files were found, and windows successfully repaired them

What was the result of enabling the verbose messages? Where does it get stuck?

I am going to have a expert look at your log.

Here's the critical error from the log...

This is a relatively common error - so probably caused by a piece of software you installed. Unfortunately, we haven't managed to work out what software, yet.

Please download SFCFix from here... http://www.sysnative.com/niemiro/apps/SFCFix.exe and save it to your desktop (we'll need it later anyhow, I think)

Once saved, double-click on it and accept the warnings. It'll run, and create a file SFCFix.log on the desktop - please upload it to your reply.
