Err.. no. HDMI working, but not VGA sounds an awful lot like faulty hardware to me. What brand of gpu do you have? What model? Find that information and contact whatever company it was produced by. (Gigabyte, Asus, MSI, Powercolor, AMD, NVIDIA, XFX, etc...). Though, seeing how you have access to HDMI output, why not stick with that? Though, I would still get in touch with them as if you have two dead outputs, god knows what else might be wrong. This doesn't sound like a drivers thing.
