Comment 1 for bug 254820

is this a brand new machine? We are going to struggle to get to the bottom of this one I think given the logs are empty, try the memtest boot option from grub, run it for an hour or 2, you are hoping for no red lines in the lower half of the screen. Try it with less RAM, as in only 2 sticks, I have seen machines not like the dual-channel memory on some types of RAM, see if there is any other similar reports on the ASUS forums. Try BIOS updates.
