I just got my new computer yesterday. The initial use of it made two freezes. I had to shot the computer down by holding the power button.
Today, I was trying to install Epson scanner, but it kept saying that OS not supported. What does that mean? and what is OS? Also something about TWAIN problem. What can I do? Please advice me. Thanks
