When I leave my mac on for a few hours and resume work again, I am unable to use the computer for about 2 minutes because it is doing something very disk intensive. After that, the mac runs fine. I am unable to pin point the problem.. Any suggestions?
When I leave my (unknown model) mac on (running some unknown version of System / MacOS X) for a few hours (in an unknown state - either with / without a screen saver or in 'sleep' mode) and resume work again, I am unable to use the computer for about 2 minutes because it is doing something very disk intensive. After that, the mac runs fine. I am unable to pin point the problem.. Any suggestions?'
Tell us the Mac model.
Tell us the System / MacOS X version.
Tell us what applications you have launched.
Tell us if the Mac - just sits there, executes a screen saver, or 'goes to sleep' - when you 'leave (your) mac on for a few hours (and before) you resume work again'.
Tell us if you are connected to a network (such as - you are at work and connected to a server).
Making some assumptions - that MacOS X 10.2, 10.3, or 10.4 is the unknown Mac model's operating system.
Launch 'Progress Viewer' (10.2) or 'Activity Monitor' (10.3 or 10.4) and determine (via the 'User Processes' (10.2) 'My Processes' (10.3 and 10.4) popup menu selection) what applications and additional processes are running. You may also want to view the processes via the 'All Processes' popup menu selection.
Click on the '%CPU' column heading to place the highest %CPU processes first (and in decending order). Now, the next time the '2 minute' delay occurs - view and note the top most process(es).

The computer only goes into screen saver after 15 minutes. Never into sleep mode. The application running at the time the computer is left for extended period of time ( ~3+ hours ) vary. Sometimes no applications, sometimes photoshop, terminal, icq, mail. I've noticed the problem is the same whether I have no applications running, or multiple applications running.
Sorry about not posting system info, I used to have it in my signature and didn't realize it was gone.
Via 'System Preferences' 'Accounts' 'Login Items' tab's panel, what applications (processes) are listed?
You can select all the processes, do a copy, paste such into 'TextEdit', edit out the names, and paste them into any reply.
The came copy, paste, edit steps can be applied to the 'Activity Monitor's 'My Processes' and 'All Processes' list of applications.
Just in case - you may have to click twice on the '%CPU' column heading (in 'Activity Monitor') to have the highest % processes listed first (in decending order).
