  1. my laptop screen has been going blank at random times for no apparent reason. It's not in sleep mode and the screen didn't shut off. I'm not sure if the computer is still responsive but i tried starting windows shutdown with the power button but it didn't work so the only way to fix it is by forcing the power off. I've also been getting this system warning in the event viewer a lot.

    Code:
    A corrected hardware error has occurred.
    
    Component: AMD Northbridge
    Error Source: Corrected Machine Check
    Error Type: 14
    Processor ID: 0
    
    The details view of this entry contains further information.

    im not sure if its connected to the screen problem or not. i googled it and other forums said it my be something with the motherboard or the power supply but i don't have the same problems as the other people had.


    specs
    gateway m2626u
    cpu: amd turion x2 2.1Ghz dual core
    ati: radeon 3200 hd
    OS: windows 7 ultimate

    EDIT: okay it seams my whole system freezes when the screen goes black. also i noticed that that the screen sometimes flickers once now. (well not the monitor just everything on the screen. the backlight stays the same.)
