Jock1e ~ you've asked me three questions I don't understand! 'last good configuration' - do you mean system restart? Don't know what tune up utilities are , so I guess I don;t use them. Don't know if this is relevant to that but I do use Soluto. And if I look in device manager what should I be looking for? I just looked and there 's a list of everything but no notations or anything. Sorry to be a pain. Isn't there something which can scan your pc to detect what's wrong?
