What motherboard does your computer have? Have you fitted the RAM cards on the same colored channels? – Doktoro Reichard Sep 2 '13 at 8:17
See if your RAM stick is supported by your mobo – Ashtray Sep 2 '13 at 8:43
Check which slot the RAM should be fitted to, it should probably be fitted using alternate slots – Tog Sep 2 '13 at 8:53

The problem is unlikely to be a Windows problem or require a Reinstall as the OS will pick it up automatically - it will either be that the RAM has not been correctly seated, or is the wrong type of RAM or the slot is not functional. Try reseating the RAM, and checking it is showing as available in the BIOS.
