    Whenever I play a game for about 3-10 mins, the GPU's memory controller load drops to 1/0% and the GPU load goes to 99% - this happens in all games. The temperature doesn't exceed 83 C, with an average of 74 C.

    It started about 2 months ago, but has gotten very bad recently. I have the latest drivers etc. and have had the system (a laptop) since december '10.

    Anyone had this problem? Any suggestions.

    What game do you play?

    Is it just one game, or a multitde of games?

    What exact gpu and make/model do you have?

    It's in all games; some I am able to play for longer (eg TF2) than others (eg ME2) before this happens. It's an nvidia geforce GT 325M (1GB) - it came with the laptop, I don't know the manufacturer.

    I've tried rolling-back & reinstalling the drivers, with no effect. Over those 2+ months I installed several different drivers & none of those solved the issue.

    That could be a possible explenation, laptop gpu's are more different than desktop versions.

    I'd look at updating your drivers, and not just your video drivers. Look to update your chipset drivers as well. :)

    i ment a proper full uninstall / delete all of the nvidia driver files.
    reboot and then reinstall them.


    make sure you delete the C:\Nvidia folder.

    Tried fully deleting then reinstalling drivers - didn't work. I can't update my BIOS because MSI doesn't seem to make an updater that works in 64-bit windows 7

    I have had the same problems on my gtx260. Is your card running hot or is it over clocked? the main reason my card was doing this was a high and unstable over clock. maby try lowering the clock speed? or crank the fan up full.

    I haven't tampered at all with it - it just started doing it for no reason - it's not overheating as far as I can tell (is an average of 74 C high?).

    To me 60 deg is hot but for vid card i would say under 80 deg is fine. just try to crank your fan up and see if that helps at all.

    Thing is though, that the temperature remains pretty much constant throughout - even when the memory controller load drops; so I don't see how temperature is an issue. Plus the fact that it didn't use to do it until recently.

    Okay. I've tried uninstalling the current driver and installing the one the laptop shipped with, with no success; so it's not a driver issue.

    I'm really despairing here - if I can't fix it that's money down the bog.
