Hello everyone, This little machine's been my pride and joy for a year. Hardly given me any trouble at all; but, since yesterday, it's going nuts. Programs close unexpectedly all the time - iTunes, Safari, Mail - and when I reopen them, it's only a matter of time (probably a few minutes) before they crash again. There's 70GB free on the SSD - I've known OS X to mess about before when the drive's been too full - and there's 8GB of RAM in it. I can't see any reason for the computer to be behaving like this. Any thoughts? Cheers, DH.
