    Hi guys,

    I'll keep this short cos I know people don't like to start reading long threads.
    My 5920G Acer Notebook freezes, mainly in the first half hour after boot, completely in Windows. I'm not sure what it causes since it happens at most random moment (not in idle though).
    It is just completely stuck and nothing responds anymore, causing me to have to reset it using the power button although it should 'automatically restart on freeze'.

    When it then starts up again, it 4 of the 5 cases it shows a black screen, not even a BIOS post. There's just nothing. The computer turns itself off again and does it over again.
    Sometimes it gets a little further (at windows boot) but then freezes at that point. Or sometimes it freezes at the Acer POST screen.
    It also seems to reset the BIOS every time this happens, since I turned the ACER screen off but it keeps coming back.

    I first believed it had something to do with heat, although the temperatures at which the computer freezed (I had speedfan running once when it crashed) were around 60 degrees for CPU and GPU and 50 for HDD (which is acceptable right).

    What I believe is that it has something to do with the GPU. Sometimes it also shows artifacts at random places on the screen before killing itself and this would also explain why it wouldn't show up anything when I turn it on.

    I'm still planning to run memtest86 to test the memory.

    What could be causing this?
    Thanks in advance.

    Hi, it sounds like it could either be ram, your test should pick that up, or the gfx card failing to intialise through hardware failure. It is hard to pinpoint but you are going through the right diagnostics, if there is a utility for testing the video card then I'd try that as well, not sure with the NV cards...

    Ok I tried, appears to be nothing wrong with memory.
    It's probably a problem with the 8600gt.
    I get artifacts more often, followed by lockups.
    It appears to happen when a fast temperature change occurs. This means, going into a game right after boot or 1 min after closing a game.

    Can this be related to the problems that were reported by nvidia a few months ago regarding the 8600 series ?

    I guess that this is your case :rolleyes: Have you tested it on external monitor? If it had the same issues, your GPU is going to die. It is just me, though, I could be wrong.
