If you have an Athlon XP or an early model Sempron then it's a no go, as the CPU lacks SSE2 which is required by Dolphin. The best way to check what your CPU supports is to download CPU-Z and post what is reported here:

If your CPU does indeed support the SSE2 instruction set, then we can go from there to figure out what the problem may be.
Things to post:
Your CPU make and model, graphics card make and model.
