How to diagnose repeated freezing of Windows 7 (comes back alive for a few seconds)

"All I had to do was uninstall NOD32 Smart Security v.3.

As far as I have understood on some systems, the Windows Defender software isn't all that compatible with ""active protection"" solutions (and Windows 7?). I never came to test disabling it and testing, but as the computer is running fine now with VIPRE I'm kind of satisfied.

These kind of problems often come from bad drivers. I installed a new chipset and ATI drivers and voilà! No more problems. Let’s hope it stays that way!"

"I had the same issue with my Windows 7 laptop. Freezing was random and between 10 to 30 seconds.

There wasn't any entry in the event log. I even tried System Monitor and similar tools to find where it was hanging, but no luck. Then I read on few blogs about driver updates and it worked for me.

In my case the RAID driver was missing.

I went to the Intel site and check all the drivers for my motherboard. There I found the RAID driver was not installed. I downloaded and installed it.

Now the system is not freezing at all."

"I had a similar problem.

My solution was when I disabled and stopped the ""Windows Search"" services. It almost completely removed the freezing. Though there was still micro-freezes of 1 second, no more."
