My system rebooted itself over the weekend. I assumed it was a
network issue since my network backup was not completed. The
crash yesterday was a lockup. However, I did not reboot when
I replaced the network driver. Maybe I should have rebooted
instead of just restarted the service.
Lack of messages is it !
ATI PCI Express 3001 FireGL video board is the only card.
Only two sticks of Ram.
I had this problem on an Asus A8V motherboard also. I replaced
that motherboard with the A8N SLI due to this issue.
The 250 GB USB drive is externally powered.
The network problem only occurs after hours of copying files across
the network. Very hard to duplicate.
Thanks,

Smartpower II 450W (+12V2 for processor, +12V1 for motherboard)
+5V@30A +3.3@32A +12V1@15A +12V2@17A

Minimum current draw on both +12V outputs is 1 amp. According to
a picture of the supply on Newegg. The Antec web page says this
minimum current is 0.4A. I don't really see the power supply being
a limiting issue. X2 4800+ is 110 watts, 110/12*(1/0.90) = 10.2A
FireGL 3100 is an x300, so I don't think it draws excess power.

I did a Google search to review your history. I think this is
roughly the hell you've been though.
1) Bought A8V Deluxe plus X2 4800+ dual core.
2) Had to buy a 3200+ to flash BIOS to 1013 to make X2 work.
3) Had network problems with the Marvell LAN. Tried an
Intel Gigabit card (82540EM based?). Computer would not POST ?
4) Switched to A8N-SLI Premium.
5) Tried many Marvell drivers. Still random reboots.
6) Tried Intel card again ?
Actually, I have some additional suggestions for the Prime95 test.
Since you are running dual core, you should run two copies of Prime95.
Apparently, there is a setting you can apply to each instance of
Prime95, called the "affinity". I'm not sure where you'll find
this, but it could be Task Manager. You want to assign one copy
of Prime95 to "processor 0" and the other copy to "processor 1".

I was reading some interesting stuff about overclocking dual core
processors the other day. A number of people had commented, that
the two cores on the X2 do not overclock equally. In one case,
the second core was barely able to meets its spec speed. A couple
of bright lads, used a razor blade to remove the heat spreader
on their expensive processors. That allowed their heatsink to be
applied right to the silicon die. To their surprise, both cores
had equal overclocks, after that modification.
The hypothesis there, is that there is some defect in the thermal
material between the silicon die and the metal heat spreader on
the processor package. These overclockers suspect there could be
a hot spot on one of the cores, caused by bad contact, or a
void in the thermal material.
I am not suggesting to anyone to get out a razor blade and try this
mod. It is much better to RMA a bad processor, then burn your
warranty with a mod like this. This is just to illustrate how a
badly cooled core can result in cranky processor operation, and
the need for a processor RMA.
So, that is why I am suggesting running two copies of Prime95
and using the affinity feature to make sure one copy of Prime95
runs per core. You may find, by doing this test, that the processor
immediately reboots, in which case you can suspect a dud
processor. You could also blame it on the motherboard, but this
is, after all, your second motherboard.
As a crosscheck, remove the X2 and put the 3200+ back in the
computer for a while. See if a network backup will run without
problems that way, and one copy of Prime95 running on the 3200+
is OK. While it won't really prove anything, other than that
the motherboard I/O devices are in fact OK, it will help point
the finger at that X2 of yours.
I still cannot figure out why the PCI Ethernet card doesn't work.
What were the symptoms when it was used on the A8V and the A8N ?
