Use the utility, Activity Monitor, to see if some problem may be due
to a need to install more chip RAM into the computer; since it will
often show there, in how the current level of resources are used.
Also, the hard disk drive may be worn as it gets older, they all do.
Could be the drive may stand to be replaced, probably with one of
more capacity and better specs, as supported by the computer.
If you copy/cloned most of the same files back into the computer
that had been there prior to using disk utility from booted install
disc to secure-erase or zero the hard disk drive, then use Partition
map GUID, followed by reformat in HFS+, the drive capacity would
still be compromised with what could still be too much stored on it.
Archiving user-created works to an external partitioned drive, where
some libraries of music and/or images may be accessed, could free
up some of these kinds of files, if set up & maintained that way.
How is the battery and charging health of that part of the computer?
Some power issues can result in a freezing activity. You can usually
see several kinds of activity in the system logs, between those located
in System Profiler> software, and those found in Console's various
locations, they may show something in regard to the causes of freezing.
And, you may be able to run some tests using the included Apple Hardware
Test, when booted into the test, that's on the original software disc.
Narrowing down a cause of various computer freezes is a matter of trouble-
shooting; finding a cause and effect relationship between symptoms & the
kinds of log files generated by the computer may help. There also is another
possibility, in that such a freezing may be related to heat. Either graphics or
computer processing units may be running hot, for whatever reason, and if
there is excessive heat that can't be dissipated that may cause a freeze.
So, there a few probable causes for the symptom you refer to.
Good luck & happy computing!
It does seem to run kind of hot so I installed an app that's supposed to speed up the fan. But I still seem to have the freezes.
I moved all of my files to an external networked hard drive to keep my onboard hard drive freed up for just the application files. And when I reinstalled software, I went right from the disk instead of from backups so I wouldn't recreate a damaged file or some kind of malware.
I'll try the activity monitor to see if I can figure out what's happening. It doesn't seem to be caused by one particular app - I usually use Firefox and OpenOffice and some of the Adobe Creative Suite apps. But it doesn't seem to matter which app I'm using at the time of the crash.
Thanks for the feedback.
Temperature Monitor is free: it creates graphs and gives audio warnings. I use it (with an ice pack) when burning DVDs. (Normally, I place my laptop on four little blocks or, preferably, a brass, legged cup coaster from India. You can judge the temperature of a PowerBook by touching the thin steel just in front of the screen.
Large applications, such as those you mentioned, often require a lot of juggling virtual memory (for it also must run all those little processes in activity monitor). The processor will run hot if your disk is too full or needs de-fragmenting. Try this, and see whether your processor heats when running large applications:
When using Temperature Monitor in some Apple Portables who also have
a temperature widget installed, you may have to choose which item you
want to represent the temperature indications, and turn off the other one.
Same in some Apple desktop computers, in my experience with both.
I've found the iStat Pro's temperature meter to be in conflict with some of
my Mac computers when using the app Temperature Monitor, so I have
turned off the iStat's temperature section. Not sure why a conflict in these
exists, but in some of my (four) computers, this was the case. However, in
a later OS X version (run mine in 10.4.11) or perhaps in an Intel-based Mac
this may not be a consideration. But if that is an unknown, it's worth a check.
Thanks for the input...
Good luck & happy computing!
The use of a widget by the name DashQuit can stop the Dashboard
and its family of active widgets from using any system resources if
they are quit this way; and one can simply re-launch Dashboard to
use the widgets there, again. Some methods of disabling widgets
are a bit of trouble for those who may not wish access terminal or
another means of minimizing the impact on system resources the
Dashboard and its widgets may add. I use DashQuit to disable it.
Contributing factors which can generate heat due to excessive or
intensive use of the computer's software, and hardware components
have to be monitored; and when someone is pushing the device to
a limit or thinks they may, it can be handy to be ready ahead of time.
I've found as a computer gets older, things run slower; so I have a
clone of the entire computer contents and can restore the Mac from
a bootable external FW HDD enclosure; and then use appropriate
tools to make best use of the free space and wiping out old data on
the drive. Plus, making the clone gives me a bootable backup.
Since rationing or carefully considering system resources can be
important when they are either lacking from the outset, or may be
pressed into a near-failure state due to overtaxing reserves, short
of handicapping the system, in some cases a tool can be helpful.
Dashquit: (appears this will work for OS X 10.4 - to 10.5.8)
Developer site shows separate Tiger & Leopard version links:
While not directly related to the main issue as presented, most of
the items in a computer can indirectly relate to overall performance.
Good luck & happy computing!
Spiffy! I'll take it!
The Dashboard had some nice uses at times, just not enough times to keep running.
Mine's a budget system. If I don't burn discs with my Quicksilver, it takes two ice packs to burn a double-layered DVD with the PowerBook.
I should probably 'max out' the RAM on the PowerBook, but the additional heat worries me. I normally run it extremely conservatively (Better Energy Savings), with an inch of ventilation beneath it.
Backup & archive
I've two terms I use frequently: backup & archive. Often I wish I, too, had taken a snapshot of my system just after building it. However, now I use a backup program to daily copy passwords & bookmarks (&c) to a LaCie key. Photos, Movies, Music, I archive to optical media and pop these in when needed. Finished projects go to DVD-RWs for a while, then the important parts are archived to DVD-Rs (with a LightScribe label).
If I need just a file from last week or month, it's in the Trash or a DVD-RW project holder. If I need a catastrophic restore, that requires just a new clean install and backup restore. (Now that 10.4 applications are disappearing, I'm archiving the app.dmg to DVD-RWs or DVD-Rs, which removes one more log file from the backup.) Small is beautiful.
In contrast to many, I believe in good maintenance; which includes using iDefrag to minimize movement of the disk head. (I would use a file-by-file backup & restore, if I made one.) I also use anachron, and 'Onyx' monthly, when I'm not using the computer.
(I used to enjoy tuning automotive engines, so I guess this makes up for that.) In any case, keeping computing resources optimized, so as not to stress the computer is, I think we both feel, like preventative medicine. There are many ways of keeping one's computer unstressed.
I like the concept of owning a desktop and a laptop. The stressful tasks are left to the desktop, and the laptop moves about. Finished projects are copied to the desktop when done.
I'm also toying with the idea of assigning all security & mailboxes to the Desktop, stripping these stressful tasks from the family's laptops. 'Firefox' has sufficient security for browsing when away from one's LAN. Web mail exists.
The point we're both making is that there are many ways of reducing the stress on your (high quality) hardware; and that can reduce health problems in the future.
Just some thoughts,
