Hi All, first time poster. I have had an issue with restarting since I upgraded using the non combo update to 10.5.8. 10.5.7 was fine however now on most occasions I get a Kernel Panic Error after the OS boots to a Desktop Screen.

I also notice Youtube videos running very slowly when in fullscreen mode.

Below is a description of my PC

Model Name: System Product Name
Model Identifier: System Product Name
Processor Name: AM2 6000
Processor Speed: 3.0 GHz
Number Of Processors: 2
Total Number Of Cores: 2
L2 Cache (per core): 1 MB
Memory: 12 GB
Bus Speed: 800 MHz

If you need more details let me know.

Is anyone else having the same problem?

How can I fix?
