- Nov 22, 2012To All,
My secondary PC has momentary hangups that last for a few seconds to
several minutes. I have Task Manager continuously open and displaying CPU
usage sorted with greatest user at the top of the list, but it doesn't show
any process using an inordinate amount of time. The greatest time consumer
is "System Idle Process" at about 95 to 99 percent. No process ties up more
than 700MB or 800MB of memory. I also observe the disk drive in-use monitor
light on the system unit and it shows only a few very short blips during
both normal and hung-up operations.
The PC isn't fully frozen during these hangups. The mouse is still active
and I am able to change state of the Num Lock key, but I can't navigate
within Windows Explorer or launch any applications or change views within
them. Even Free Cell pauses.
The machine contains 2.40 gigahertz Intel Core2 Quad processor and 3 gigs
of DIMM memory running WinXP SP3 with all updates current. I have done a
recent CHKDSK and a disk defrag. Microsoft Security Essentials updates
every day and runs a full scan on all disks without reporting any malware.
All operations on this computer appear to execute without errors. The only
problem is the momentary pauses.
Any ideas what is causing these hangups? Any further troubleshooting ideas?
