Just speculating: PC hardware uses the keyboard controller to generate the reset pulse. On some older hardware, this fails. The CPU is not powerful enough to generate a clean reset pulse, too. You may either remove boards (thus reducing the load of the reset line), or replace the board. To put it short: It is a hardware problem I have seen in older PCs now and then.
