System restarting its self and Apps shutting down on their own.
Mac mini (PowerPC) 1.5 Ghz, 512 Mb RAM, Late 2005 with OS-X 10.4.11
Seems to work fine but after 5 minutes it just displays you need to restart press and hold power button
Safari & Firefox just close by them selves
I Run Disk utility and repair folders permission and so but still the same.
Is this a good question?
