What brand is the Power supply? Start there. If it's a cheap tacky unit, get it replaced immediately. Your system draws a reasonable amount of power, and that power supply is unlikely to be able to keep up. Secondly, I assume all this is second hand? If so you need to be able to guarantee it all still works.
