but I got a list of 'things to do with your new computer' and step 5 was to update drivers and firmware. Are you saying, Mark, that the ones installed on here already should be good enough for now? Should I delete what I have downloaded but not installed? TWB404, thanks for the link will go there. I did think long and hard before buying a ready-built computer and didn't think I could build my own but have heard a lot of good about going that route - maybe for the next one. I so appreciate the help I get on the forums. Thanks.
