Lately I've been experiencing slow downs, crashes, non-responsive apps and sometimes when I shut down my computer it gets stuck at the little twirly loading thing over my desktop image. I've repaired permissions, checked the disk, everything, and I'm still getting these problems.

I've installed the following apps recently:
DropBox
Microsoft Office 2008
Tooble
Flash Player 10 Beta
Safari 4 Developer Preview
Disk Inventory X
 
i agree, sounds you ram is faulty. check the ram sticks individually and make a backup if you can. it could be that the ram starts writing garbage to your hd and you lose data.
 
I just ran a test on my RAM and it's fine. I can't physically check it right now, but if the test comes out positive then there shouldn't be a problem right?

No , sometimes these things don't show in the test .

Take out the RAM , re-seat it then start up your Mac .

😱 -how did you manage to run the test yet you cannot physically check the RAM ?

I'll give that a shot when I get the proper tools.

Um...you don't need to.
 
You can boot up with the install disc (disc 1) and hold down T (I believe, might be D). This will bring up a 2 minute test of the RAM.

But as mentioned about, it still might be something physical with the RAM that the test isnt picking up.
 
The RAM seems fine. I quit DropBox and Quicksilver took them out of my startup items and restarted. That seemed to have worked, according to activity monitor, they were both using over 800MB of virtual memory.

That's a lot right?
 
Known bug

You're very likely running in to the 10.5.3 hang bug. Wait for 10.5.4, downgrade to 10.5.2, or see if Apple has any work-around by calling them.
