hi. recently i have been having trouble seeing/playing things on the computer. For example, scrabble on FB, videos of film trailers and national lottery scratchcards (instants)
i thought it might be flash so have just installed flash version 10.3 but no difference -what other application could i need to make them work? It only seems to be since ibe pgraded to IE9
I think that you were correct in the first place. It's probably a Flash problem. However reinstalling (or upgrading) Flash doesn't work if your computer recognises that Flash is already present (even though it's not working).
Reboot your computer, pressing F8 as it goes through the initial sequence. That will take you into Safe Mode (so that programs which normally start 'in the background' won't do so). Your display will look very odd (because the video driver won't have loaded) but you'll then be able to uninstall the Adobe Flash Player Plugin.
Then reboot (to get back into normal mode) and download Flash Player again.
