    My mid 2007 MBP seems to be locking up during CPU intensive tasks, such as, emptying the trash containing large files and other tasks that make the fans scream. Two things were done before this issue has came up. First I installed a OWC 3G SSD and then I upgraded to Mavericks when it was released. I even get lock ups while just surfing, but usually it's when I'm multi-tasking or something as stated above. Any thoughts?

    thanks in advance! below are my system configs.

    Next time this happens look in the console log for relevant error messages.

    You also might try a command-r boot to recovery and use Disk Utility from there to do a disk repair and see if any errors are found.

    Also try running the Apple Hardware Test.

    Do you still have your old drive? I would pop that back in and it would tell you if the new SSD is bad.

    okay...yeah i have run the hardware test a few times and it showed nothing wrong. i'll try the log next time it happens. i still have the old hdd and was thinking of swapping it out to check, but wanted to make sure it might not be something OS related before i did that. thank you!

    just an update...after a lot of troubleshooting, i have decided the problem exists while using Mountain Lion or Mavericks. so far i have zero issues while using Lion. what is causing it specifically shall remain a mystery i suppose.

    This is just a theory but you may want to look at enabling Trim on your SSD (if it supports it) Not having TRIM enabled can cause a huge performance drop while write operations are happening which might explain a few of your issues
