I now have a Dell E520 with Vista (Core 2 Duo E4300) purchased after my emachine died in Jan. Bought two 1GB sticks of RAM to add to the 1GB that came with it (Vista just seems sooo slow) and can not get any combination to boot up. In the past, any RAM additions I have made were "plug & play"...Any thoughts? Couldn't find anything out of order in the Setup.
