iMac 20" 2.4 momentary freezing

[grinningmouths]

Has anyone had any problems with their new iMacs momentarily freezing?
I've noticed in the last week or so mine has been doing this quite a bit. When i'm watching a video on youtube or even just scrolling through a web page it will freeze every now and then for about 2 seconds and then go back to normal. This happens about every 10 seconds on a youtube video. Just looking at activity monitor now and it says safari is using about 20% cpu and this other process called windowserver seems to jump up to around 35% when i'm scrolling through web pages. Is this normal?

I've also noticed that when i'm playing counterstrike it does the same thing with video settings on medium.

This is alot worse when using firefox! Firefox-bin process goes up to about 75% cpu when scrolling web page.

You're lucky your freezing is only momentary. Mine freezes up for good. I have to hard boot it 3-5 times a day.
