Re: Screeching on start up and streaming video, help!
Uninstall your sound drivers, uninstall your graphics drivers. Update them with the latest versions.
If you don't know where to get the latest drivers from, post up your sound card model number (or motherboard model number if the sound is onboard) and someone here will find them for you.
"As a result of all this hardship, dirt, thirst, and wombats, you would expect Australians to be a sour lot. Instead, they are genial, jolly, cheerful, and always willing to share a kind word with a stranger, unless they are an American." -- Douglas Adams
