Hello everyone,

I have a Macintosh Plus that I got a couple of years ago. When I first got it I had a problem where I would turn it on, it would come on, get as far as the flashing question mark icon on a floppy disk, but after a fraction of a second on that screen it would reboot. It would continue doing this until it was manually switched off. After about a day, the problem went away, and I never thought much about it.

I had not used it for quite some time (a few months), but when I turned it on again today I found that this problem had returned.

Does anyone know what is wrong and how to fix it?

Thanks,

Andrew
