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.

 

 

A few more details:

 

Model Name:          MacBook Pro

  Model Identifier:          MacBookPro3,1

  Processor Name:          Intel Core 2 Duo

  Processor Speed:          2.4 GHz

  Number Of Processors:          1

  Total Number Of Cores:          2

  L2 Cache:          4 MB

  Memory:          4 GB

  Bus Speed:          800 MHz

Also, I replaced the internal CD/DVD drive with a second hard drive a while back - the second drive doesn't do system stuff, and is used for video and audio data.

 

Over to the hive mind...

    You have one of the MBP with the NVIDIA defect unforunately (GeForce 8600M GT).

    The scrabled screens are the GPU overheating and failing.

     

    Apple had a repair program that has now ended.

    You can still try making a genius bar apointment and asking about a flat rate repair or take it to an authorized Apple service provider.
