something wrong with my GPU card

Yesterday I run my cuda program and
found that something wrong with my display…
According to my experience , I just need to restart my computer…
The problem will be resolved…
But…after restarting the computer…
The display problem is still existed…
ex: the icons of desktop can’t be displayed correctly…

About my CUDA program…
In order to avoid copying the data from GPU → CPU…
I called the openGL instruction to create a buffer to store it …
After doing this…the display problem was existed…

Does anyone have this problem…? Please…help me… External Image

It will happy when you do sth wrong with the GPU memory…

eg: write memory to wrong place. check it.

what~~~!!!
If I do something wrong with GPU wrong buffer…
How can I recover the GPU memory ?

sorry!

That means memory access error. It’s not hardware^_^
