iMac is suddenly running very slow!

[Babs330]

Hi everyone,
Within the last few days my iMac (Mac OS X 10.5.8) has started acting up. It is running very slowly. I have over 100GB of space left. 4GB of Ram.
I have been so worried that I have tried everything, including a virus scan (which I knew would be useless) and turns out I have no virus'. I have repaired the permissions on my HD. I have also rebooted it a bunch of times, did a software update.
Things like my hot corners won't work. My dock doesn't pop up when I run my mouse over it. Right click is VERY SLOW. It's gotten so bad that when the screensaver on my iMac turns on the motion of the mouse doesn't do anything. I have to actually push a button on the keyboard for the screensaver to go away.

Please help. My iMac is sick and I feel like a bad mommy! lol

it might be some software that was recently installed that has memory problems. how much RAM are you using.

I haven't installed any new software in months.
I'm only using about 1.47 GB of ram.

Any other suggestions?

Even if it isn't a HD issue, you might want to take this as a reminder to back up if you haven't already. Activity monitor might help to see what's using what resources.
Did you recently update or install anything?
