    image.jpeg So my mid 2012 13inch MacBook Pro keeps freezing and then restating. It's been occurring more frequently, and it makes it hard to do anything on my computer. I have recently installed new ram and a new hard drive (it started after the ram so I wonder if that's the issue?) I've attached an image of what the screen looks like before it shuts down.

    Has anyone else experienced this problem/ knows how to fix it?

    Thanks!

    What results to you get after booting to your Hardware test?

    Ideally, try it as soon as possible after you get a freeze/restart.
    Run both the standard and extended tests.

    Bad or incompatible RAM can cause what you're seeing. Reinstall the old RAM and see if the problem goes away.

    I would think it's a video issue. Seems to me to be a video distortion.....

    13" MacBook Pros use system memory for VRAM. Bad RAM can cause video issues like this.

    The 2012 models have common failure with the RAM slot on the bottom. You can verify by running with 1 RAM stick only in the top slot.
