Try removing everything that is *not* absolutely needed in the computer. Ie all the cards that are not needed. Could be one of those causing the problem. Remove *one* of the memory chips if possible and leave the other in. then change it over. some systems will allow this. remove CDROM temporarily if not needed etc.
Also unplug/replug in everything a few times as mentioned in another post. check that there are no bent pins on devices too. swap keyboard and mouse, monitor if things start to get desperate. I've had them cause computer hiccups in the past. take an image of the machine that you can restore later with imaging software and install the operating system again. if it falls over again it's most likely hardware... perhaps... you know... try different stuff...
