Can't watch video and play games that require flash player

I'm using windows7 family premium version

internet explorer 10 last version 10.0.5

exploitation system 64 bytes

flash player verson 11..700.202 the latest one

So as i say can't watch video and play games that require flash player, they keep asking me to install flashplayer... i did everything i read in the forums, unistall it, clean the memory, reinstall it, disabe active x etc... but still have the problem.

More specific about my problem is that: let's say that i'm trying to look at you tutorial video under thi forum  Re: How do I fix Windows permission problems with Flash Player? i'm just seeing a black screen.  So I'm able to guess where is the play button so when i push on that place, i can hear the sound of that video.  Second step guessing where is the  enlarge  button, and when the screen is enlarged, magic i can see and hear the video.... So you figure that it's impossible to use my computer like that and guess right all the time, so....

Second fact, it seems that bug happened after an update (windows or explorer) and i even talk with a microsott tech who was not able to resolve it... But if i'm  undoning  the update and go back to a prior image, i have no problems with flash player anymore... it' been moths that i'm delaying my updates cause i cannot find any solutions.... So Please please please, help me .... don't know what's the problem is and i'm not a pro, don't know what to do.  (Excuse my english it's my second language)

Thank you
