I am posting this thread for a friend as I was unable to help myself.
He recently has been getting BSOD when using youtubemp3 converters or websites for similar purpose. Also videos will sometimes just turn into a green screen.
He's using a Dell Laptop on Windows 7 & wasn't able to tell me the model so far, but as soon as I can get that info from him I will post it up here.
Many thanks in advance for any help!
