Vio Laptop
Some problems after upgrading to Win 7

I own a vio laptop (1GB RAM) FJ-VGN-FJ57GP model.

I reformated from Windows XP to Windows 7.

All else is fine but when I connect it to LCD Projector for presentations, it does not send signal to the projector. The function key F7 does not prodcue any results.

PLS help URGENTLY by calling me at 098212 77330.

Thanks
