    Default Random freezes

    Hi,

    I have a GA-MA785GMT-UD2H board with onboard Radeon HD4200 and AMD Phenom II X2 545 and 4GB Corsair DR3 SDRAM.
    I was running Vista Business X64, now running Windows 7 Professional X64.
    I recently started getting sporadic freezes, no response to keyboard or mouse, reboot only way out.
    Have run Memtest and Lavalys Everest stress test on memory, cpu etc. Nothing showed up.
    Suspected might be GPU so put in latest drivers from ATI.
    Still get freezes.
    Is there any diagnostic package I could use to pinpoint the problem?

    Do you get the same error if you fully remove the ATI Drivers?

    If you don't then that might be the problem and you would need to try an older/newer version.

    I can't really help with AMD, but I can tell you that you should at least be setting your memory voltage to spec and if using 4GB you will also need to increase NB VID (Northbridge Voltage, may be named differently)

    Thanks for your input.
    The system had been running OK since December 2009.
    The freezes started a couple of weeks ago while I was still running Vista and were not the result of any software changes, hence my feeling that the problem might be hardware related.
    Only put on latest ATI drivers as part of Windows 7 upgrade, but will give it a try with the windows drivers.

    Well you upgraded your OS, so that may have partial blame as well. Did you upgrade to win7 or do a clean install?

    Have you since installed all the latest chipset drivers too?

    Could be hardware, can you test a different GFX card in your system?

    Also test your memory with memtest86+

    Problem was occurring prior to upgrade.
    Have tested with Memtest86 and also with Lavalys Everest.
    Neither showed any problem with memory.

    Will try a different GPU and will also try with Windows 7 drivers instead of ATI.

    It would be nice if there were some way of testing the GPU.



    Thanks again for your help.

    Did you test with the very latest Memtest86+ that I linked? Just wondering, and if so or not, how long are you testing? 5-10 full passes is suggested.

    You can test the GPU for heat, and see if that causes it to produce the same error. If so then that might help you narrow it down, use this but watch the GPU temps
    FurMark: Graphics Card Stability and Stress Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net

    Test at a few resolutions, use stability test and just watch it for errors or overheating (it does not stop so you need to stop it manually)

    Thanks again.

    I had already used Memtest86 and Everest before starting this thread.
    Did the full 10 passes with Memtest86 and also did full stress test with Everest on CPU, FPU, Cache and Memory.
    Nothing showed up which is why I was looking at the graphics side.

    Will give Furmark a try.
