got a infuriating issue with a hp w19e monitor and vista
a monitor alert screen pops up at random
it has a blue border, about 4 inches on each side and says audio 100%
its not telling me what is wrong
often it will not go away and just sits in the middle of the screen
if i hold in the auto button on the monitor it will sometimes
dissappear but will pop up again randomly
before vista was loaded we had no issues like this
my sound is working fine and music plays ok

hp have not been helpful with this issue

thanks in advance for any tips or info
