Might it be temperature issues? Dust gets into everything.
Thanks Ken, Bengt, It's not temperature. (I regularly put a thumb-tack through the fan grill to peg the fan and run a shop-vac over both sides to suck the dust-bunnies out. If you try this MAKE SURE you have pegged the fan, otherwise you will wildly overspeed your fan. Also, if you get dust-bunnies sucked up against the screen from the inside when you shop-vac it, just rub a bit of hook-velcro over the screen on the outstide and it will catch and pull them through... :) After another 3 hour memtest run, I do get a couple of errors on random bit test 7 near the end, 2-new sticks of pc2-5300 SODIMM ordered. Had to cough up $19 for 4G. I'll set you know if that does it. Bengt, glad to see you use a heredoc similar to the way I use it for small C code tests.
