Sometimes my computer locks up after I install my memory. Could the new memory be the problem?

Possibly. Remove the memory and see if the problem persists. Reseat the memory module into the socket and see if that solves the problem. Try rearranging the order of the memory in the machine. Some computer power supplies don't output enough power (or other components may pull too much power), either of which can deprive the memory bus of the appropriate amount of power. If the problem persists, try the module(s) in the system alone. If the problem goes away, it could be a compatibility issue with the existing memory. If this occurs, or the problem persists, please contact us for further assistance.
