@FreeDuck,
It's funny you mention the battery, because ever since I bought it, the battery never lasted as long as the manual said. But it shuts off when I have it plugged in as well. And I tend to have it plugged in a lot because I never trust the battery. About 1 year after I bought it I had the battery replaced. And the new one did the same thing. The manual said 4 hours. I would say I got a good 2 hours at first and then just over an hour.
I'm starting to think I just bought a lemon to begin with. But it's not very old, about 4 years.
Yes it is slow after shutting down normally, and I am the type of person who does not like short cuts. I use them once in a while but as a habit I always open and close things step by step. For example; to shut down I close every window, go to start, click on log off, wait...and then click shut off. I always open things through Start never desktop icons, my kids yell at me sometimes, "Mom you don't have to do all that you know!" Ha Ha Ha. Just under three years after I bought it, I remember because I got it fixed just before the warranty ran out, I had about a 1 and 1/2 inch solid black line running vertically, about mid way through the screen. I had the screen replaced, so the whole thing about the screen saver from the other kind person on here I'm not sure about. I have a screen saver and a background. And the wait is set at 60 min.
It also gets very hot and always has. I can hear the fan running, but yet still it gets hot.
So if I understand correctly, it's not shutting off because of FAT32. FAT32 is getting the error because it crashes. So I need to figure out what is making it crash. If it's getting so hot maybe it's over heating? But I turn it back on right away and it could stay on for another couple of hours without a problem.
It's an ACER by the way. Ever heard of them?
