Black screen Playing Videos dilemma desperate for help …!!

[romancenmore]

[CLOSED] I’ll try to make it short , downloaded & interrupted an active X which resulted in a black screen whenever I playback a video ( WMPlayer10, Nero 8 , Quicktime , Divex NOTHING WORK) (audio is fine ) , I tried the following (NONE worked ) :

• Rolling back wm11 to 10 & Reinstalling wm player 11
• Installed & Uninstalled à XP_Codec_Pack_2.4.1 , Nimo50Build8 , Codecs6030_allin1 , klite codec417
• Scanned registry using Mechanics
• Ran Gspot and sherlock2.0 didn’t show any missing or corrupt codecs (UNLESS I dono how to use it )
• Uninstalled codecs from Device manager à sound , video& Game controllersà video codecs à properties (removed one by one )

other things noticed :

• Video played back just fine when booted from my other HD (vista)
• prompted when downloading codec pack to delete a broken registry which I did
• the only time I am able to playback video is when running VLC media player (choosing Direct X or Open GLwithout hardware acceleration )
