Toshib A100 display is split into 4 parts

Hi,

The display screen had a black strip of 3" on the right side and 1/2" at the bottom. I was told by updating the BIOS and the chipset should solve the problem.

I updated the BIOS from the download from Toshiba site, as soon as the flushing was completed it rebooted and displayed 4 equal split screens on the display.

I need to get rid of this 4 equal split screens, what should I do?

Your help would be appreciated.

Thanks
