Sounds like a good power test failure- put the memory back in, unplug the power connector and IDE cable from the hard disk, then try to boot up. Proper pin alignment must be maintained on connections. Some IDE connectors are not keyed and the connection could be reversed. Also it is possible to plug the power plug in to the hard drive upside down- opposite of normal.

A number of other things could be going on with your system components, anything could have happened- e.g. static discharge from your body could have damaged something on the motherboard?
