Help, Screen randomly blinks black for a second

[CrackheadKyle]

Please Help,

At random intervals I notice my screen blinks black for about a whole .5-1 second at just completely random intervals.

Whether in Firefox, in game, steam, wherever I am at. I find it gets even worse whenever I have to alt-tab. It has been doing this since

Thursday when I logged in. After being annoyed by the blinking I updated from 375.95 to 376.19 in nvidia (I have a GTX 1070). My

Monitor is brand new and I tried replugging HDMI, etc to no avail. I tried going through Task Manager. Nothing. I tried checking

Super Anti-spyware and Malware-bytes. Nothing. Not even a cookie. Do I have to update chipset? BIOS? Revert Nvidia? This blinking is

slowly driving me nuts so I would like some help. Thanks in advance.

I had this problem before once. 

Try making sure your PCI-E cable is in snug to your graphics card.

Ok, I dusted my computer, cleaned the contacts of video card and I check status of cable. Wire looked worn and like you know like kinda bent with the little indent in it so I switched 6 pins and I made sure that and 2 pin was secure. They both came off with minimal effort and when I put them back on they were a bitch to do so. Therefore I suspect the problem has been eliminated with securing cables. I will come back to this thread however If I notice anymore of the blinking however I have been in Firefox and Steam which would normally trigger it.
