    I have a MacBook Pro from around 2010, and it has functioned perfectly up until recently. I just completely wiped and reinstalled my OS to see if the problem would be solved: no luck.

    What's happening: every once in a while, my screen will go blank and the computer will shut down. However, the keyboard stays lit up the entire time. I've recently noticed that when I'm not using a mouse, this either doesn't happen or it hasn't happened recently. I've also had problems with a SanDisk flash drive- when I plug it into the USB port, the computer inputs will freeze up. I can still use a mouse if it's connected, and the computer is still functioning. However, the trackpad and keyboard are completely non-functioning.

    Has this happened to anyone?

    Any ideas?

    Thank you!

    trackpad and keypad not functioning translates into a failed usb hub on the logic board. Does the usb port work fine ? if it does then your only option other then replacing the logic board is to use external keyboard and mouse.
    I had this issue on my macbook pro, it hung and crashed when i restarted both trackpad and keyboard would not function, so i took it to the AASP a few days later they told me they are replacing the mainboard as when both fails its a problem with the usb controller.

    Thank you!

    Got it. This sounds like the problem I have when I connect my USB Flashdrive. The other USB port still works but it's annoying... I wonder what the cost of fixing that would be.

    Right after I posted this on the forum, however, my MacBook restarted itself a couple of times without anything plugged into the USB drive. Any ideas on what this could be?

    I was doing some research and came across 'Kernel Panics'

    This appears to be exactly what my computer is doing. It was doing it beforehand, but I decided to reinstall my operating system. However, I lost my re-install disc and thus downloaded and installed a bootlegged copy.

    Because it was doing the Kernel Panic before this, I don't know if this is the issue. Is there a way to get replacement operating system install discs? Is this issue even related to the Kernel Panics?

    kernel panics usually occur due to hardware faults.While sometimes it can be software to. If you could post the starting few lines of the crash maybe we could help you.
    Include just 10-15 lines.

    You know what... when I click 'Report' after the computer reboots, nothing pops up. Is there a way to show past reports/error logs?
