hard drive problems - no more posting

Apparently my third hard drive is going to fail. I thought I had a virus attack, which might also be the case, but I ran a hardware test first expecting a message about the battery. When this hard drive was put in just before the end of the warranty in Sept 2016 I got a message indicating that they had sent it back with a bad battery. The combination of Dell and Costco has not resulted in a good purchase for me.
