Sometimes, my PC (win7, 64 bit version.) will freeze for 5-10 seconds.

  • Sometimes the mouse cursor still moves, but my actions do not do anything. Sometimes the mouse cursor is frozen too.
  • It usually happens a few minutes after boot, but well after all the start-up tasks have "died down".
  • One of the most sure-fire ways to induce it is to browse to a stackexchange site that uses the LaTeX plugin. Math Stackexchange will do this almost every time, but only the first time I visit it.

Based on cursory research my first suspect is the HDD so I:

  1. Updated the drivers of the motherboard and the bios to the latest version.
  2. Read out the SMART data of my disk. It shows the disk to be healthy with 0 recorded retries.

The problem still persists, and it is quite annoying.

Can anyone offer any specific insights, or point me toward a general troubleshooting strategy?

Additional hardware/configuration info is of course available upon request. I did not with to spam the question with my shopping list, as I presume most of it is irrelevant. – drxzcl Sep 22 '11 at 9:16
    
adding to what Red said, the w7 Resource Monitor is some kick butt tool, wow i never thought about it even, it is ONE thing in 7 that is cool and functional and usable :-) – Psycogeek Sep 23 '11 at 14:22

Using Sysinternal ProcMon should help you identify what is causing the freeze.

Process Monitor is an advanced monitoring tool for Windows that shows real-time file system, Registry and process/thread activity. It combines the features of two legacy Sysinternals utilities, Filemon and Regmon, and adds an extensive list of enhancements including rich and non-destructive filtering, comprehensive event properties such session IDs and user names, reliable process information, full thread stacks with integrated symbol support for each operation, simultaneous logging to a file, and much more. Its uniquely powerful features will make Process Monitor a core utility in your system troubleshooting and malware hunting toolkit.
