[ale] Losing stability

[Andrew Brown]

Another lil cheat is to run knoppix or other live cd linux flavor. If it
boots up and runs on the disk without the beeps or sticking, then you
know it is the HD and not the mboard, memory or the cd drive... if you
are getting the same problems you know it likely isn't the HD. Running
this with the memory check will give you a broader look at what could be
the cause. 

Just a thought...
