>>Just a thought...Does that computer use shared video memory (with RAM)? Also, need to consider a bad network cable and/or network card, check IRQ's to ensure that you are sharing the NIC IRQ w/another device. Try using hooking the computer up at another connection first to check the cable.<<

We chnaged to 800x600 256 color display mode and no more lockups. I am leaning towards the video driver as the culprit.
