Hey there John and Welcome to CompuForums!
Thanks for registering, and I hope that you come back often and post in other topics.
You can find out your socket type and more with the application CPU-Z. Just download it, unzip it and run the "cpuz.exe" file. Under the Main tab, the "Package" box will tell you your socket type.
Download CPU-Z from:
