I'd be running a RAM test.

Try out Memtest86 - I think it's also usually an option in the boot menu on Ubuntu live-DVDs.

Let it run overnight, I've had crashes like that before where the RAM only starts failing after a few hours of memtesting.

I tried to work around that by trying different RAM sticks. 2 initial + 2 new, both sides, swapping, using only one, etc.

I guess next step would be Memtest! Thanks for the reminder.
