I seem to have the same problem. My television screen goes white and I have to turn the computer off and back on. It seems to happen more when I have bigger programs in memory, for example a 4K Basic putt-putt game or a 2K determinant program. Does anyone know what causes this? Can I correct this with a bigger power supply, or should I use a more (physically) stable connector for the memory? Will permanently attaching the ram pack to the computer via some sort of clamp help any?
