I've had everything protected through battery backup/surge protectors for 15 years and always thought I was covered. Our power blinked the other day during the hurricane. My console and monitors were plugged into the same USP or is it UPS battery backup and they are fine. But, I realize that doesn't really mean anything. Regardless, I think I should do as you do and start unplugging the backup unit from the wall when not in use.
Scott, you mentioned caps on the mother board. I hate to sound so dumb but I have no idea what you are referring to. In short, I'm a little over my head. My son is a bit of a computer geek, hoping for a little help from him. Thanks for the input guys.
