I am getting brief pauses every few seconds on my win 7 machine. It's pretty new, just win7 and vmware installed.

Every five seconds, the system pauses for a second. It's very annoying. Ideas?

This is a brand new system that I just built and seemed to work ok a few days ago.

If you have WiFi, one reason for such freezes might be Windows periodically scanning for wireless networks (even if you are already connected).

You may disable this behavior using WLAN Optimizer or Vista Anti-Lag (the latter is for Vista but may still be worth trying). They should be used with "run as administrator".

In theory, if you are already connected to your most preferred wireless network or if you have disabled the "automatically connected to more preferred networks" setting in your wireless profile (default setting on new profiles), then wireless scan is already supposedly disabled, but sometimes it is not.

Please let me know how you are connected to the Internet and whether you have a wireless network card.

Might want to check DPC's and IO activity, a faulty HDD could cause it. Use the following resources to determine this:

To determine System Activity/DPC issues: http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx (run as administrator)

To determine potential IO activity the former tool may help, but use "Resource Monitor" - access it from your start menu. Be sure to look at the HDD and Memory tabs.

On the memory tab look at the Hard Faults/Sec value, on Disk look at Queue Length, and Response time.

If the issue is DPC related, you might be able to mitigate it by increasing your PCI Latency Timer in BIOS.

Simply use ProcessLasso. ProcessLasso will try to improve system responsiveness during high load periods.

If there's still the same problem, do following steps:

  1. Reboot your system in Safe Mode (during boot, press F8 to bring gateway to safe mode).
  2. Use the system same way in Safe Mode.
  3. If there's no problem in Safe Mode, reboot your system normally and close unnecessary processes using task manager. To know about a process, simply Google process name.
  4. If the same problem arises in safe mode too, simply re-install Windows 7 or restore to factory backup image.
  5. If there's still the problem, time to contact manufacturer support because there's a hardware faulty. I hope, your new system is under warranty coverage.

Alternatively, do following steps:
1. Download setup of Windows Performance Analysis Tools for your Windows version.
2. Install the software on your system.
3. Right click command prompt icon in start menu and click run as administrator.
4. Copy following command and paste in command prompt (right click > Paste): 

xperf -start perf!GeneralProfiles.InBuffer && timeout -1 && xperf -stop perf!GeneralProfiles.InBuffer myTrace.etl

5. Press ENTER once to start the command, now you will have to wait till your system hangs.
6. Right after your system stops hanging you, press ENTER in command prompt.
7. After waiting some time, a log file myTrace.etl will be produced, compress this to a zip file.
8. Host this compressed file online (on MediaFire etc.).
9. Share the link here, I will try to find a solution to your problem using that.

Uninstall Adobe Flash Player.

I'm running windows 7, and had downloaded the 64bit Adobe Flash Player from their website.
