If you have a clock showing seconds, is it still ticking?
No.
Even, if power is OK, hard disk may lock up for other reasons as mentionned above.
All IO is dead as a result of the crash.
Have you tried running the system from LiveCD with no HD connected at all?
Yes, still crashes :(
If loading video content causes the crash, this may suggest it occurs on high cpu load. I have seen cpus locking up when throttling up and down under changing load. Can you set the system so cpu throttling is turned off and see what happens but probably means it will run on rather low frequency? (a bios option?)
Loading video is a more or less reliable way to force a crash. However, system load does not appear to be the cause. I've had the system crash a number of times recently just reading email or sitting idle. I don't have any CPU frequency scaling tools installed, and I've been reluctant to mess with the BIOS settings and introduce more complexity into debugging. The system had been stable for some months since assembly with the present settings. Might be something to look into later though. Cheers, Dave
