Well, far as I remember, That stuff has gone since well Windows Vista.
Youre talking about the tests etc right?
If so, then yeah, that feature was removed since Vista was in private beta..
To test your videocard/s use 3DMark Vantage or what ever they call it.
There are many sound testing apps out there, sorry I can't think of their names
One that comes to mind, but bare in mind that it's a 30 day evaluation is Passmark tool
So far looking at your screenshots, you got nothing to worry about "No problems found"
