I just upgraded to Windows 8 and doing normal browsing in Firefox I am having the computer lockup and I must force restart using the PCs button.

Are their reports of this? What can I do to solve this issue?

Does it blue screen? – Louis Nov 19 '12 at 22:18
    
@Louis - No just stops completely. Mouse will not move, nothing responds. I have given it a few minutes to see if it would unfreeze but did not. – L84 Nov 19 '12 at 22:21
    
Okay. Well, the only thing I can say is that I've had the same problem, except it turned out to be a HW issue with MacBooks. It didn't help me, but people have had success by disabling dynamic ticks, a new power saving feature in Windows 8. If you try it and it doesn't help, you can always undo it: bcdedit /set disabledynamictick no – Louis Nov 19 '12 at 22:30
    
@Lynda hardware config? – pratnala Nov 20 '12 at 2:28
    
Is it possible that you could list the updates that were installed since the issue was resolved? It may be beneficial for some users. :) – Brutick Nov 20 '12 at 18:51

After having this issue I ran Windows Update and installed several updates. This has since resolved the issue.

Here is a list of updates installed:

  • Update for Microsoft Camera Codec Pack for Windows 8 for x64-based Systems (KB2712101)
  • Security Update for Windows 8 for x64-based Systems (KB2727528)
  • Update for Windows 8 for x64-based Systems (KB2756872)
  • Update for Windows 8 for x64-based Systems (KB2769165)
  • Update for Windows 8 for x64-based Systems (KB2768703)
  • Update for Windows 8 for x64-based Systems (KB2769034)
  • Security Update for Microsoft .NET Framework 4.5 on Windows 8 and Windows Server 2012 for x64-based Systems (KB2737084)
  • Security Update for Microsoft .NET Framework 3.5 on Windows 8 and Windows Server 2012 for x64-based Systems (KB2729462)
  • Update for Internet Explorer Flash Player for Windows 8 for x64-based Systems (KB2770041)
  • Update for Windows 8 for x64-based Systems (KB2772501)
  • Security Update for Windows 8 for x64-based Systems (KB2761226)
  • Update for Windows 8 for x64-based Systems (KB2770917) Note: This update - KB2770917 - would not install automatically and had to be done manually.

These all installed at the same time (save for the last one) and I do not know which one resolved the issue.

I think it might have been KB2756872 (support.microsoft.com/kb/2756872), it appears to be the only one to improve performance, but it's hard to know for sure if that is what fixed the issue. – Brutick Nov 21 '12 at 16:02
