Problems with Blender 64bit install

Hi, can anyone help me with this. I have installed blender twice and have the same problem. I am missing menus and buttons from the screen as you can see below. Has anyone come across this problem before? I am using Windows 7 on a 64bit machine. It is the 64bit version of blender. I would really appreciate any advice with this.

Pic “Blender sd1” shows what my screen looks like.

Pic “Blender sd2” shows what my screen should look like.

I’ don know what is but seems like a video card driver issue, try to update your video card driver;)

I can’t see yor images but if you are missing buttons then probably a permissions issue. Run blender as an administrator. If you installed onto an external drive try installing on the C drive.
