As to the system crash, now is the time to make sure your restore media and files you can lose are handy and on backups.
Running Win 7 64 bit on Asus G60jx - Keep getting "The properties of this item are not available" every time I click on the properties button for any of my hard drives, but I can get the properties for files without any problems. Please Help. I'm afraid if this goes on the system will crash.
