Thank you for reading this post
I am running Kubuntu 8.04 AMD64 on an Athlon 4000+ with 4Gb of RAM, two identical SATA 500 Gb HDD, two identical GeForce 8600 GT 256 Mb Graphics Cards on SLI. The Motherboard is an ABIT KN8-SLI.
I have only one problem: Sometimes, randomly as far as I can tell, the system freezes completely. The screen(s) freeze, the system becomes completely unresponsive, Ctrl+Alt+Backspace will not restart X, I cannot invoke the task manager and waiting does nothing (I've experimented waiting up to 6 hours). The only thing I can do is a hard reboot, and then the system reacts as if nothing odd has happened.
I apologize, I know that I am giving next to no information...
I don't know how to diagnose or begin to investigate this problem, any pointers are greatly appreciated.
Here's the output from sysinfo:
