It is possible someone tried to overclock the memory, and or the CPU which can manifest strange problems usually with random issues, but can also appear to be reproducible. Power supply problems can also have similar effects. You may also want to get a can of compressed air and blow all the dust bunnies out of the machine and its power supply, then remove and reinstall all the cards, modules and memory sticks. While performing this task you may discover, that a fan is seized or something was loose. You may also not discover anything wrong, and the problem may persist, but at least you now have clean parts to recycle. ;^) By the way, I use some 300 MHz P3, Compaq Deskpros for R&D and testing. They work fine for that but will likely never be reimplemented. It is fairy easy to find small format low power consumption machines with a lot more processing power than your HP for a fairly reasonable price, and they will support newer drives.
