Screen Flickering

[Keltoid]

I have both a main monitor and a second monitor. My second monitor does not flicker. The main monitor usually flickers during big movements such as moving tabs but doesn't happen during games. It usually happens during or after using microsoft powerpoint but also randomly (may have a pattern which i don't see) . I tried changing the dp cable but that did not work. I have updated my video drivers twice now from nvidia and still doesn't work. Does anyone know how to fix this?

If its possible to make a video of it happening it might help people offer suggestions for what it might be.

I can't really make a video because i never really know when it will happen. The flickering has no colour to it. The pixels just turn black for a couple frames and then back.
