Folks, thanks for the replies, To answer a few questions:
Have you completely exercised the memory for at least a day using memtest86? And, are you *certain* it is the correct rating for that board? Can you rule out any questions in this regard by swapping with known good modules or falling back to one at a time and then the other?
I have not run the memtest program but I installed DDR400 ECC Registered memory as specified in the manual, but that is something I can check once I get some additional memory.
Does it freeze on it's own, seemingly randomly (no one at keyboard) or does any user activity (or even a specific activity) trigger it? If the freezes are seemingly random, is there at least some kind of discernable common timeframe?... i.e. minimum uptime of 20 minutes; after 3 hours, etc. ... or can the machine run for days before suddenly freezing?
It seems to freeze on its own as well as when I am using it. I have cron jobs that run to download info. It usually does not freeze when they run, but I have known it to do so at least once. I initially thought it was the mouse, so i switched mice - no change. Sometimes I can use the computer for days without hanging. The only significant telling activity is disk activity. Recenty I have tried to copy large amounts of data from the SATA array to the PATA drive. After a few seconds or sometimes minutes, the system hangs.
What power supply do you have and how big This is a fair amount of hardware for a single power supply so you want to ensure it is sized correctly... you don't want a convergence of simultaneous subsystem activities to momentarily outdraw it's capacity. This is especially true if you've got a high end graphics card with lots of memory to power. (You didn't state your graphics setup.)
I am using a 460W power supply, but I will consider an increase. I have seen failing power supplies cause strange/random activity in a computer before - so I may in fact work on this issue first.
Have you tried any of the special boot parameters, i.e. failsafe, disabling acpi, etc.?
I have disabled ACPI on the board and use noacpi parameter on boot, but the system still tries to start acpi anyway. I have also disabled the NV raid, but linux detects it and loads the nv_sata driver too. I have rmmod'ed it but it does not seem to make a difference since there are no drives attached to the controller.
Does it get hot !!?? How about airflow !! The CPU's run at around 114F and 120F respectively (not sure why there is such a big difference) and system temp is ony 113F according to the bios.
None of the components seem unusually hot. The drives are actually cool to the touch so I am not inclined to think there is a problem with heat. Thanks for the feed back. I will try replacing the power supply first and report back when that is done. Stuart On Friday 20 January 2006 03:34, Carl Hartung wrote:
