I would also note that leaving it for a few hours is generally recommended. I have used memtest86 to identify a few bad sticks of ram and all have shown errors within the first few tests, but it cant hurt to run it a little longer. |

In addition - if you have multiple DIMMs and find one is bad, run memtest again after removing the faulty DIMM to make sure the others are fine. |

As for the graphics card in the system in question - check that the cooling fan is working correctly. I had some awful artifacting in Linux on a card a year or so ago when the GPU fan snuffed it and the GPU was overheating (the heatsink was hot to the touch such that you couldn't hold a finger on it for long!). |
