And although it starts and picks up the load in 10 seconds or so, the damage to a computer may well be done before an incandescent lamp is dark. So I'll take the 2gig dimm out and reseat it a couple times, and reset the bios to defaults and turn the hyperthreading back off, then see if memtest86 will run. If not, I'll check the other supposedly identical box as a src of supposedly good memory. But its out in the shop building at about 40F. So that won't get done this evening. This is the short, fat sticks that lay well down like used in lappy's. 2G's worth in both boxes. Thanks Przemek Klosowski.
