I recently put together my new Haswell build. I've been using the integrated graphics until I can get my graphics card. My issue is that it randomly stops displaying and my monitor goes into sleep mode. the system itself continues to operate. I would like to point out that it didn't start doing this until I replaced the stock cpu cooler for the noctua nh-d14. I've been tracking the temps to see if it was a heat issue and it stays right around 30c. Another thing is it only does it when I try to open/close a program, when it is just idling it's fine.
Is this a known problem when using the integrated graphics or could it be something else?
