There are issues with the ECS K7S5A boards in general, but don't get me wrong, I still like it. Some boards have a problem with excessive voltage to the SiS 735 chipset. This can exhibit itself in several ways, most of them intermittent. Also, you can upgrade the BIOS with one that has more control over the clocks and voltages. Here's a couple of links: a Google search. and more on the voltage problem.
