If you have several sticks of ram and did not install at least a stick properly, the system cannot use it and will not register in windows (right-click, "My Computer", see "General" tab). If you only have a stick of ram and it was not installed properly, the PC will not boot and will start beeping.

To permanently get rid of them, the Hard disk need to be reformated and the OS re-installed. If you have other hard disk volumes (whether physical or different partitions within the same hard disk), make sure there are no viruses there also before reinstalling the OS.
