since I got the iMac going i've been plagued with problems when using flash and/or my webcam.

anything with Flash makes the fans go mad til it's closed down - if I use it for more than 10 mins I get a Kernel Panic.

Ditto for webcam, although this lasts less time wise.

Any ideas? I have latest version of Flash player and the correct driver for the camera - I use the latter for VOIP and was fine before I installed tiger.

Ignore the 9 in the title, typo!
