My old 17" MacBook Pro (the 3,1 version, running 10.6.8) seems increasingly slow, and i think it's more than just the comparison with a newer and whizzier 27" iMac... I seem to have experienced many more incidents in the past few months where I've been twiddling my thumbs waiting to switch between applications, between Safari windows, or for the thing to simply wake up. Also a few incidents where the screen became scrambled, and I then had time to take a picture of said scrambled screen, see...
My hard drive isn't too full (about 20% free space)... so:
• Can anyone suggest a couple of good routes for troubleshooting here? Maybe tests I can run to see if everything's running as it should? (It's taken a couple of knocks over the years, had to replace the screen, and my simplistic take on these kind of repairs is that when I put it back together it's either going to work perfectly or hardly at all... but maybe that's not quite right.)
• Do those screengrabs suggest any particular kind of trouble?
It might be almost time to retire the old girl, but I'd rather keep her going.
