I sort of understand what your saying i'm still pretty much learning and 
breaking things regarding linux :-)

I have had this machine running unbuntu and fc2 fine before no random 
rebooting, although fc2 did need a modified i586 kernel as suggested by 
the fedorafaq people, this fixed the random reboots on that, but seems 
no such fix for fc4 as of yet.

I haven't tried memtest no, or looked in the syslog, but I will give 
those things a go and see how I get on.
