My computer has been having an issue where I am having intermittent "Not Responding" messages across the board. Almost all programs (especially Firefox) will occasionally go non-responsive for several seconds, then wake back up. Opening the Task Manager seems to almost always immediately wake up all the process again.
I've ran virus scans, diagnostics, computer cleaners, updated drivers and software, ect. No viruses, not even any warnings in the diagnostics, and I cleaned out a good deal of garbage using CCleaner. I have checked the system error logs, and no significant errors are occurring regularly.
The problem has gotten better, but still exists. At this point, I would like to see if I can figure out what is going on when the issue occurs. To me, this looks similar to a process or thread locking issue, where some process is taking extraordinarily long to handle interruptions or to release control of the CPU. If I can figure out what process that is, maybe I can find a fix for it.
So I wanted to know if anyone knew of any program which will allow me to watch which processes currently have control of the CPU, so I can figure out if there is some trend going on.
Thanks in advance.
