That's a good idea to try atleast Martin, I have also seen some really weird behaviour because of powersupplies that are faulty. One minute the pc works fine then ram disappears on next boot and you think it's faulty ram, then the hdds will disappear completely must be the board and in the end it's faulty power :/. Short of replacing all my components I don't know why mine won't suspend. Intel Core 2 Quad SSD 120gb Nvidia 480 gtx 4gb DDR3 ram
