Homebrew PC with:<br>
A8N-SLI Mobo</a> With "Cool-Pipe" (liquid-cooled) technology (the fan
just NEVER turns on)<br>
AMD Athlon 64 X2 4200 Dual-Core Processor<br>
2GB DDR2 Memory (4-512MB DIMMs, cannot recall make or designation)<br>
2-160GB Western Digital SATA HDs, configured as a single 16GB /boot

Running FC5 with up-to-date PlanetCCRMA packages including the latest
I'm running the GNOME desktop. I also have an <a

49e MIDI keyboard controller</a> hooked up through USB.<br>
Several times now since I've had the system up and running (about two
weeks), the system has just "frozen up" in a very un-Linux-like manner.
Everything just stops. I have left it sitting overnight, hoping that it
would come unstuck somehow over time, but it appears to be a permanent
session-death. I have to to a hardware-reboot (which I hate to do on a
Linux system) to get it back up and running.<br>
I have the following questions:<br>
1) Any ideas as to why this is happening?<br>
2) Where might I be able to find information (e.g. log entries) that
might help me pinpoint the cause?<br>
3) What are some recommendations for other diagnostic measures?<br>
BTW, all the above components are new, except for two of the memory
DIMMs, which are a few months old. There shouldn't be any "memory
incompatibility problems" as I have the DIMMs in separate banks, but
if, say, the memory specs ARE different between banks, could that be
the culprit?<br>
