Sound and Video Problems

[BananaMann]

Operating Windows 7. Recently updated itunes. flash player, and downloaded RealPlayer.
At some point (& I'm not sure when) problems started on sound & video.
Itunes- click on song just sits @ 0.00 no playback
Youtube (Firefox) plays 11 seconds with no sound then freezes
Youtube (IE) plays sound & vid for a few seconds (once) if it's the first audio use after logging in then will sit @ 0.00 for subsequent plays (bar shows it is downloading the whole vid.)
Windows media centre will not play anything either except when first operated as in (Youtube (IE) above).
Since the problem started I used a restore point before Itunes updated. Have removed all 3 programs & reloaded Itunes & Flashplayer (not RealPlayer)
Thanks for any help that might be forthcoming.

Try doing a System Restore to before you did the updates. If that fixes it then update one at a time until you find the one causing the problem.

Nope same problem exists.

Maybe try an earlier restore point? I'm wondering if a Windows Update was the real cause?
