Late yesterday my 4 year old Dell Inspiron Laptop started getting blue screens. The situation deteriorated, and this morning while in Safe Mode, the computer went completely dark. Now it no longer powers up at all. Fortunately, I have a backup laptop, which I am now using. I've spent the whole morning updating the McAfee virus checker, Windows 7, Acrobat, and RegCure.
I think I can recover my critical files by taking the hard drive out and using it as a portable hard drive -- this is not hard to do. I'll attend to that later.
