A few days ago my daughter got on the pc and couldn't hear anything. "no active mixer devices available" I investigated and found a solution online (i can't recall exactly what it was..embarassed**) yesterday i updated my flash player to ver. 10 the problem with that was it would never install. I investigated that a little as well and in the process i deleted my old version as part of someones solution. another part of that solution was to get the current ms updates which i hand picked 3 since there were no critical ones available. the would update. my screen froze forever and i abandoned ship with the power button. buit befor i did i noticed the taskbar had gone gray. now it goes gray randomly and freezes up....any ideas?
