    Hi, I've got two GTX 560s in SLI using the latest drivers from nVidia (320.18) and GPU-Z is crashing on launch instantly at the splash screen.

    Anything I can do to help fix this?

    I'm running Windows 7 x64 fully patched

    Are you willing to try a few test builds? Do you have an instant messenger? Skype (just text chat, not gonna call you)?

    turns out I had slightly out of date onboard Intel HD 3000 drivers and it was causing the app to crash. Epic response time to the dev!!

    Same problem

    I just installed a EVGA 670 Signature 2, and GPU-z 0.71 is crashing upon launch.

    I'm using the Nvidia 320.18 drivers. System is:

    i5 750
    8GB RAM (4 x 2GB)
    Gigabyte P55A-UD3R
    Windows 7 Home 64-bit

    Any suggestions what might be behind this?

    I tried an older version, 0.6x, and it did the same thing. Also, I installed EVGA Precision X, which bundles Riva Tuner to monitor stats, and that also crashes - RTTS.exe. Though it might be related?

    Thanks.

    when you start gpuz after the crash, do you get an opencl warning? like "opencl crashed last time gpuz was loaded. do you want to disable open cl detection?"

    No I don't get any such warning. I looked in the error log and it's some sort of exception handler with an associated dll. I can't remember off the top of my head, but I'll post it this evening when I get home from work.

    I am worried because I picked the card up second hand and want to make sure it's ok.

    Thanks very much for the fast response!

    Do you have an instant messenger, so we can go through a few test builds ?

    Daneel, the latest nvidia 320.18 drivers are known to be problematic in some cases, so perhaps try rolling back to the previous driver and see how you get on?

    I was experiencing problems with other apps, not just gpu-z, and after a lot more digging, got to the bottom of it - DisplayLink. I was using it to allow my iPad to act as an external monitor. It worked fine with my Radeon card, but seems to interfere with the Nvidia driver.

    I hope this information helps :)

    so did you uninstall the displaylink software? or upgraded it?

    old gpuz works now, too ?

    I uninstalled it. GPU-z 0.71 now works perfectly.
