I have a Mac G5, dual 2 GHz with 1 GB SDRAM and 2 hard drives, each 500 GB. I am running OS 10.5.1. My computer is soooooo slow! In the past few months it has gotten increasing slower until it is now just infuriating. It doesn't matter what application I'm using, it just drags. I haven't installed any new software. A few weeks ago one of my hard drives started knocking so I replaced it, but I was having speed problems before my main hard drive went out. I had hoped that when I replaced the hard drive my speed issues might be resolved, but they weren't. My internet is fine; it's just my applications. For example... if I click on an InDesign or Quark document it takes a couple of minutes for the document to open. What can I do to speed up my computer? Please help!!!!

How much free space do you have on each of  your drives? If you are running out of room for your virtual memory file, that will slow things down.

Does this happen when you have only one app open? If it only happens when you have a lot of apps open, then you probably need more RAM.

Use Activity Monitor (found in \Applications\Utilities) to see if something is hogging RAM or CPU time. You can sort the list by either CPU time or RAM usage.

Download and run the DNSChanger Removal Tool to make sure you have not picked up this Trojan which can slow things down:


Is there any possibility that your other drive is also dying? What result do you get when you run Verify Disk in Disk Utility? Also check the S.M.A.R.T. status of both drives.

You might also download and install SMARTReporter:  http://www.versiontracker.com/dyn/moreinfo/macosx/23232

Finally, download a utility like Onyx http://www.versiontracker.com/dyn/moreinfo/macosx/20070  or MacJanitor http://www.versiontracker.com/dyn/moreinfo/macosx/10491  and run the maintenance scripts to clear out old logs and caches.

Thanks tons! I actually tried everything you suggested and something worked b/c so far my speed seems to be back to normal. I didn't have a trojan and I have more than enough ram. My hard drives tested out good so I am guessing it must have been the cache, etc. I used MacJanitor and Onyx. Thank you soooooo much for your help!!!
