Windows 7: Need help diagnosing intermittent and temporary partial freeze

Need help diagnosing intermittent and temporary partial freeze

I've been experiencing an intermittent and temporary partial freeze and don't know how to narrow the cause any further. The main thing I do on my laptop is use Firefox, and about once per hour it will put up a spinning icon and not respond to any input. At this time I can still move the mouse and bring up the start menu but I can't launch anything. I also can't open the task manager. After about 30 seconds all my input will suddenly be processed (windows/programs that I tried to launch will open) and everything will be back to normal. This issue started about 4 months ago.

I ran Process Explorer in the background for multiple days as a test and when the issue occurred the CPU usage was not spiking and often it was <10%. I looked at the event logs and there are no administrative events around the time of incident. For example the issue occurred around 11am today and I only have a single event log from today and it was an error at 9am related to DHCP. I don't think they're related but I do get the DHCP error quite frequently: "Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x001558C348B2. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server." The network address it mentions is my active wifi adapter and I haven't had any issues with it.

My SSD claims to be healthy according to Samsung Magician software. I've got about 20% of the drive free. I'm typically only using about 50% of my available RAM.

In device manager I see no error icons.

Not sure how to diagnose this issue further. I'm tempted to switch to a different browser, but the fact that it seems to lock-up more than just the browser indicates a more fundamental issue. Any advice appreciated. Thanks!

You can try:
Open Task Scheduler (Start menu search)
Enable All Tasks History
When lockup occurs come back and refresh
See if you can find anything (select Task Scheduler (Local) - Task Status (Last Hour))

Does it happen with a clean boot? Troubleshoot Application Conflicts by Performing a Clean Startup

Thanks, I'll try the Task Scheduler approach first, and then try the clean boot. Might take me a few days to gather the data but I'll report back.

Well the Task Scheduler history didn't show anything when the issue occurred, so I've moved on to trying a clean boot.

Haven't had any issues since disabling various non-essential services and startup apps. Overall things seem more responsive too.
Thanks for the help GokAy!

Always run a Clean Boot with only your AV and synch starting with Windows.
