Query: Crucial 2GB 256Mx64PC2-5300 CT25664AC667 DDR2 200-Pin SODIMM Laptop Memory

I purchased the 2GB memory upgrade as suggested, when I purchased my HP210 notebook. I have tried several times to install it, however without success. All I get is a blank screen when I turn the notebook on. I am very pleased with the notebook, but don't know what to say about the memory card as it does not work.Crucial 2GB 256Mx64PC2-5300 CT25664AC667 DDR2 200-Pin SODIMM Laptop Memory
