Hi,
Image files don't show up on the screen when I do stop signal task.
I posted about this problem few years ago, and I wonder if there is any solution for this problem now.
It works fine when there is only visual stimulus in script, but it doesn't work when there are both visual stimulus and auditory stimulus in script.
I can only hear auditory stimulus, but can't see any visual stimulus.
I also tried to change image file format (png, jpeg, bmp...), but it didn't work.
I updated graphic driver to the latest version, and checked if there is any problems on it. It was ok.
following is information for my laptop.

windows 7 Enterprise K, Intel(R) Core(TM)2Duo CPU, 64bit, 6.00GB ram,
Geforce with CUDA (GeForece 9300M GS),DirectX 11.0 version.

I wonder how I could fix this.
I would appreciate any comment.
Thanks,

I am (still) reasonably certain that the problem is caused by a faulty graphics card driver. Given the age of the card and that laptop vendors often do not provide the actual latest drivers, it may well be that even the latest one available for your system still contains the bug.

The only solution is to find a driver that works. You can

- Try to obtain the latest drivers from nVidia directly (not from the maker of your laptop or via Windows update) or from another laptop manufacturer that used the same graphics card model in their machines.
- Try *older* drivers available from your laptop's vendor. With a little bit of luck, you'll find one that works.

Hope this helps.
