    out of spec voltages are often the first sign of a failing PSU. and can cause all kinds of strange system glitches. I would replace the PSU AFTER double checking them with another program. Check the voltages shown in the bios under computer health.

    Ok i checked my voltages in my bios, they were as follows:

    Vcore 1.50V
    +3.3V 3.23V
    +5V 4.91V
    +12V 11.52V

    To me these look fine, but im kinda noob when is comes to voltages,
    So are they alright??

    It could well be that MBM is showing the wrong voltages. Download the free Everest programme and see what it says your voltages are.

    The voltages reported in the BIOS are always correct (and they are within limits in your case), but alas, your system is not under normal operating conditions when you are poking around in the BIOS setup. The GPU is virtually idle and most peripherals are not doing anything either.

    As howard said, try several programs in case one of them just can't get your readings right.
