problems

Start with Sony.

If they do not have the drivers available for download, then you need to determine who's chipset Sony used for the motherboard, and the graphics, and download the correct drivers from them.
(Intel, AMD, SiS, ALI, VIA are a few chip mfg.)

To help determine whos chips are on the board, try utility programs such as Belarc Advisor, or Sandra

Also, you can look at your user's manual to determine the model of your graphic card, and go to their website and download the driver. Or literally, you can open your computer and look inside, read what is written on your graphic card. Also you can go to
control panel/display/settings, your graphic card model should be there, presuming it is not erased, just not behaving properly.

I can't find the model number that your looking for go to this url and all the support pages for F Series Sony Vaio's. http://www.ita.sel.sony.com/support/link_fseries.html

Good luck...
