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!). -- djn Disclaimer: I represent no-one else in my emails to this list.
