nMP GPU issues

[macuser1967]

Hi,

I've been getting a lot of screen glitches and freezes recently and I was wondering if anyone had similar problems. I'm uploading couple pictures of the problem.

Also, I've upgraded my ram back in june but I only started to have problems last week. Should I reinstall the original ram just in case apple might give me a hard time about it? The ones I got are mac certified.

Thanks

I've seen some other post have similar issue, and end up is the graphic card's (VRAM) problem.
