I just built my first computer. But for whatever reason, it continuously keeps beeping. I have taken the CPU out and applied new thermal paste but when I go to turn it on, it just keeps beeping. I have a GIGABYTE GA-78LMT-S2P motherboard and a AMD Phenom II X6 1045T CPU. If anyone can give me any recommendations on how to get it up and running, that would be great. And also does the absence of a video card effect it. I am still yet to buy a video card. Thanks
