Query: Computer cuts off with new memory

I ordered 2 sticks of memory (512 MB) for my Dell Dimension 2300 to try to increase its performance. The installation for memory sticks is pretty simple and they appeared to be new and in good condition. After installing I rebooted the computer, but before it was fully rebooted, all power was shut off. I started the computer multiple times with the same results. I tried switching the positions of the sticks, placing only one stick, and using one of the new sticks with the old sticks...same results. I had a local tech come by to give me his opinion. He believes that either they're defective or noncompatible and should be returned. He also said that I should probably go with a more trusted memory maker like Crucial or PNY. I've reinstalled the old sticks and have no problem with the computer turning off. I've contacted Buy.com about getting an RMA for returning the items...We'll see.
