TCS,
You were right; it had diagnostic start up set, probably from when I had problems before. So, I put it to normal start up, and had the same problem; it died in the middle. So I started in Safe Mode, put it back to diagnostic start up, and it gave me the choice of starts again, and now it starts fine, but...I'm back to not having the whole screen!!!! Now now I suppose I'll have to try to remember how to install the video driver again. This is ridicuulous. If I can get it working again I might just leave it. But if you feel like send me a pm with a phone number, maybe we can sort this out...if you can be bothered that is.
Posted 5 minutes later...OK, panic over; I've reinstalled the video driver and got my full screen back. I'll leave things as they are I think. I think when it seized up again it ask me to check settings(?) in Config.sys(?)...though I panicked too much to take it in. Also, all this happened when I installed Norton anti-virus; it was fine before that, I think. Does that give any clues? Anyway, as it is, I love it...so maybe I'll put up with its strange ideosyncracies until or unless I can find a tame expert to fix it. Any volunteers?
