Command Shutdown Don`t Wokr Completely

Everybody hello!
In one moment my PC with standart shutdown function don`t turn off completely. (FAN and all hardware work) (sweat)
Before standart shutdown function I used kshutdown, but kshutdown don`t turn off PC again.
PC shutdown off completely only when I use command halt in GRUB, with root I can`t shutdown PC completely and last what I can see after standart shutdown is message: PC will be shutdown immediately.
I boot from LIVE-CD with OpenSuse 10.3 - and shutdown was correct (fans stoped and power work as ATX)
I don`t modify kernel, only I install AMD/ATI Radeon drivers.
[22:19:37] … How I can repare this mistake???
Opensuse 10.3 - 64-bit!
Sorry for my english and good luck!
