Earlier tonight Tsunami's laptop started producing a very high pitched squealing sound. She thought it might be her hard drive - it did sound a bit like a bearing failure - but to me it sounded more like audio feedback; it wasn't, but it sounded much like that. Then, about an hour ago I had the same thing happen as soon as I connected to a particular site. I was googling at the time and shut down the link so quickly that I'm not sure where I was. Tsunami's computer went to the BSOD [blue screen of death] and required a re-boot. A serious error was detected. Then, all of her inbox mail in Outlook Xpress was gone. Later it reappeared with nothing other than a virus scan done! No virus was detected. Since in nearly 20 years and seven computers I have never seen this happen, it really got my attention. Any ideas? Has anyone else had this happen?
