I am having this problem recently whenever I am using my PC my moniter would go black and back on again and yesterday I was just browsing the web when the same issue happend again but this time the screen had white, green and pink stripes in the middle and them went back on again....It doesn't happen to me that often and when the issues accures I can still hear (let's say) a Youtube video playing in the background. I didn't overclock my moniter or my cpu or gpu....so is it a problem with my moniter? Or could it be an issue with the HDMI cable?
