Problem with taskbar Zorin Os 6.4

Hi, I have installed Zorin Os 6.4 Amd64 core with windows 8.1 on a notebook Acer Aspire 5630 with Intel Core Duo 1.66 Ghz and 4Gb of RAM and graphics card Nvidia Geforce Go 7300 and 128 Mb video memory, well, I have a problem with Zorin Os 6.4 is that when you sign the taskbar will only see a piece of the top and the icons and the rest of the taskbar not seen and have to log off and log back on to make it look correct, how can I fix ?, I would appreciate if you could help me fix it. Also want to tell you that my hard drive has a problem because he has "relocated sectors Counter" Zorin be why you are failing? I also want to tell you that Zorin OS 9 is apparently not compatible with my Nvidia video card and I can not prove it from the live cd mode, as the screen goes black. A greeting just install it and the screen goes black. A greeting and thanks.

If you are having graphics issues with 9 try doing the text-based install method by decalman:
