[SNIP] That's a stupid crash typical of windoze, but unusual in linux.

People have mentioned cooling, and memory faults. Check them.
Apart from that, back off the memory timing a little, and try booting
with "acpi=off noapic" as boot parameters.
I've a via chipset & XP here also. Fine box. But the apic (Interrupt
Controller) implementation is broken on the via chipsets. In my case
everything (all 4 parts of the sound, ide0, ide1, lp0, com1 & com2) get
either irq 10 or irq 11. Things that can _acutally_use_ irq 10 or 11
(usb, nic) get some half assed irq. You end up that the box thinks
something is one place, but the card ether can't go there or thinks it's
somewhere else. So you get spurious interrupts because everything jumps
when one irq is touched, and dead items because the irq is unreal, and
the drivers won't use it. acpi (newer power management) is also hairy,
but it doesn't matter as much.
The possible interaction on boot could be because windoze sets up the
irqs a little differently.
