Sony Vaio Screen Goes Black

Sony Vaio Screen Goes Black

My Sony VAIO FW screen goes black when I try to spend a video (YouTube) in full screen, but audio still works?

I watch videos on YouTube, for example, the small screen in the normal, but if I try to change the size of full screen, the screen goes completely black, but the audio still playing. The screen does not return until press escape, then return to the small screen. Does anyone know what to do?

The flash is installed incorrectly. Uninstall the current, go to http://www.adobe.com/products/flashplayer/, Click Download, click Download and select Save, not run, when finishes downloading close the browser and double-click the downloaded file. When the installation is done reboot and go where you want and try.
