So i've recently upgraded my system OS to Windows 7 64 bit and all was going smoothly and great. However i've recently noticed that whever i view videos on the internet (youtube etc) i can hear the audio but there is no image only a green background or screen.
Now this is on firefox (which worked fine before, yesterday in fact) not Explorer 8 as i cannot get flash support on that. I'm not sure if i even have flash for firefox as adobe are 'working' on compatibility for 64-bit browsers at present.
Anyone know how to fix this problem?
