IMac kernel panics and freeze

Question

My iMac is one year old and has worked fine but two days ago my iMac G5 (w/ iSight) started crashing and the kernel panic message comes up. So when I force restart I get to the log on screen and then the mouse freezes. Sometimes, I am able to log on but then about 5 minutes later the mouse will freeze again. This has been an endless cycle for these past two days. Luckily, I am using my iMac G4.
I tried resetting the PRAM and PMU, but it didn't work.
I tried installing the 10.4.9 combo but it didn't work either.
My computer doesn't fall under the repair extension program.
I don't know what the problem is :[

Hi
I am not sure if this is where I should put this, but, looked up kernel panics - yours is the most recent one! I had one today, and had not had one for years...
So - here it goes - I'll copy and paste...
I haven’t had a kernel panic for years – but today I did.
Here’s what happened:
On the internet at the school where I work. Just had Mail open – nothing else. Went to shut down, and the panic thing showed. I pushed and held restart, and it just shut down, and did not restart.
When I got home tonight, it started, said that OSX had quit unexpectedly – and I had the choice to report or not. I clicked report, but nothing happened. So I am posting this as suggested in Mac OS X: How to Log a Kernel Panic
Thanks.

I have updated to 10.4.9
Hoping this gets looked at by Apple or Dr Smoke...!
Thanks
