    Okay so when I plug my power adapter into my laptop it charges is but as soon as i put a big load on it as Unigine Valley the laptop instant turns off.

    It IS charging the battery and can play games on battery but as soon as I plug it in and give it full 3D load it dies.

    740QM
    M6000
    150w PSU

    When this happens is the adaptor also dead? (Light off) until you replug it?

    If the answer is yes then probably the PSU is bad.

    If no and the adapter light is still showing after the laptop shuts off then it could be a more serious motherboard or gpu related problem.

    Sounds like a bad PSU.

    Hmm, I wonder if these m6000 cards may be the culprit. Have you tried replacing the m6000 with your old GPU to check if these problems repeat?

    Would be very strange if this were true.

    I didnt think other than the 580M there were any cards that posed a problem to the M15x.

    Gofspar can you confirm the problem has disappeared?
