    Windows 8.1 64 bit


    Temps look good before the crashes. It's a laptop so it runs a bit hot but nothing went over 65 C before the crahses. If it is a problem with my GPU how would I go about fixing it? I know that the video card is on the motherboard itself so I would I have to replace the entire thing?

    From what I was able to find, the GPU is soldered to the motherboard on your laptop (the Lenovo Y580).
    As such, you'll have to replace the motherboard in order to replace the GPU.
    Good luck!

    Alright, luckily I didn't have to replace the motherboard. I found a relatively easy fix which and haven't crashed in about a week or so. Using MSI Afterburner I was able to lock the clock speeds of my GPU to the 3D clocks. Before launching a game I just run Afterburner for a minute or so and then boot up a game. I'm not sure if my GPU couldn't throttle itself to full speed or what it was, but if I manually set the clock speeds it doesn't crash. Thanks for all the help, I really appreciate it.

    I'm glad that you found a fix for it.
