Big Problem after Update 10.5.2

[ebbyd]

Hi everybody,

 

if searched a lot to fix my problem but nothing to find.

 

First my hardware:

 

- Pentium D 2,8 GHZ

- 2GBDDR2 Ram

- Geforce 7800 GS

 

There was no problem with 10.5.1 kalyway. I decided to update with kalyway combo update to 5.2 and everything works fine.

 

But no after boot if got every 15-20 seconds a cpu increase to 70% from the kernel_task. So every 15-20 seconds my mousecursor freeze, videos stop and keyboard freeze. It's very f**** up.

 

Could anyone please help to fix my problem ?

 

Sorry for my english i'm from germany;)
