Thanks again, Milo, will have a look at ebay.au. when I get time. The first time the thing wouldn;t boot up, I took it to a computer shop and they reseated the hard drive, when I got it back, the scroll keys and the ? didn't work. Then last week when it wouldn't boot up and I reseated the hard drive and got it to boot up, the other keys (see previous post) didn't work. And still don't. That's why I thought the 2 problems were related.
