[opensuse] System shutting down problem

I am using Open Suse 10.3 HP Compaq Presario C555 TU. I have got problem in shutting down the system at times. At the last moment of the shutting down process, the screen becomes coloured and nothing happens after that and the system does not power down automatically. Kindly help me to trouble shoot this problem. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
