Why does it crash? SSD or switching graphics

    Hello Forum,

    I've had crashes now recently since i put my OCZ agility 2 240 GB SSD in. It just freezes one app after another and a reboot is required. It also crashes at the login screen if leave it there without typing my password for 5-8 seconds. (weird huh)

    So, what do i do? is it really the ssd? it usually happens when i'm doing a lot of full-screen app switching so maybe it's the switching of the video cards (integrated vs discrete) ? I'm not sure

    Any tips or help will be greatly appreciated
    Thank you

    it's not your graphics switching; you can rule that out (at least, with the way you described it). The graphics switching on a MBP happens when you open or close apps that request the dedicated graphics, not when switching to them. So switching between full-screen apps doesn't switch what graphics card you are using.

    Looks like the SSD is the culprit to me... are you on the latest firmware for it?

    Correct me if I'm wrong - but the OCZ update is simply an EXE that will run within DOS. (via the command line) Create a bootable CD-ROM or USB with FreeDos on it, and drop the EXE updater into the root directory. Boot from the CD, run the EXE, and update the drive.

    Please reference this thread on OCZ for instructions:

    There will be at least one bootable image that you can use to launch the tools. Its actually pretty easy once you figure out the image that works for you. The only special thing required is to run an enable AHCI script. Depending on the image, the script may actually enable AHCI and run the update utility. If not, there is no harm running the update utility manually.

    FWIW, I have 7 Sandforce based SSDs and all are very stable.
