    Hi,

    I'v recently faced some problems with my c90s.

    Problem is as follows:

    When I turn on any game that uses 3d, problem appears.
    After few minutes into game notebook starts to hissing strangely. I think sound is coming from left side where CPU and GPU is placed.
    Also there is really little change in monitor brightness when that hissing starts and also a little lag on game.
    After a while notebook turns into 'power saving mode' same as when AC is unpluged for maybe a half second then into 'normal' mode same as when AC is plugged. And this continues, 'power saving mode' / 'normal'.

    I'v unplugged battery and when this problem appears c90s shuts down without any error message. Then I have to turn it on with power button and everything appears normal except 'unexpected shut down' information after BIOS is loaded.

    I'v used CUPID Hardware Monitor to check temps.
    In normal mode [on desktop] / specs when game running:
    Motherboard: 60C / 78C
    CPU: 56C / 76C
    GPU: 74C / 87C
    Battry Voltages: 12.44V / 10.22V <- [minimum value]

    So this problem appeared 1 day ago and I have this notebook for maybe 4years now and it's first time this happening.

    I would really aprecciate some help. Maybe someone run on this problem before.
