Image Distortion/Flickering lines

[Dklovedaisy]

I've been battling with my computer for well over a year now diagnosing issues. It flashes lines on my screen, different color squares, black and white checkers, and almost anything else you can name. I sent back 3 monitors, two being the same kind before opting for a 4th different one as my final. I've also sent back five 1080 ti's, which have have all "failed" Zotac's testing facility. I am just getting back the 6th which "Passed." Don't even get me started on the nightmare they have been. I don't know whether my motherboard is potentially the issue and is corrupting the GPU's, or it is some other hardware issue. I've screen shared with a computer technician, and he is unable to see the issue when it's happening on my end. We've ruled it down to a hardware issue (we believe). I've sent in the motherboard, and it also came back with no issues. I've tested all four sticks of my ram individually. I've used onboard graphics to see if the problem persisted (it did). I've tried to use four other monitor cords (HDMI and DP) all which came with my two monitors and the problems persisted. Alt-tabbing is extremely slow and causes the screen to flash black and also sometimes flash lines.

 

All of my drivers are up to date. Same thing with BIOS. I've tried 3 different versions of BIOS, a fresh Windows install, manually installing drivers, etc. all to no avail. I've found one other person with the same exact issue before, but it was back in November 2017. He never figured out the issue and stopped responding.

 

I'm including a couple links with video of the issue happening. It has also distorted my monitor which did not go away instantly like in the videos.

Thanks in advance for the help.

Might be an issue with your power supply (not necessarily the computer's power supply, might be 'dirty' mains electricity) or your display cable, I've had similar issues happen when I had a bad HDMI cable that would cause the display to occasionally flicker like that

I have it plugged into a surge protector with my monitors plugged into it. It might be the protector not being able to provide enough power, but I doubt it. I'll have to pick up a new one and see if that fixes it. I've four cables in total (2 HDMI and 2 DP) which didn't fix it. It happens on both of my monitors where it will flash different colors of lines. Might just have to send in my PSU and see what they say.

if you managed to murder 5 GPUs, i'd rather think of the power supply or a serious fault in one of your monitors.

I honestly doubt they were actually DOA. I sent in GPU after GPU and they only said it's broke and sent a new one within a day that they got it. This last GPU they spent about 5 days testing and actually sent pictures of it on the test bench with pictures of it running correctly. Don't know if I got lucky or if they finally just tested it. The same problem persisted the same exact way through 5 GPU's so I doubt it's the GPU that's the issue. Onboard graphics shows the same issue without the GPU plugged in. Probably is PSU since I've used 4 different monitors.

Definitely sounds like the PSU or surge protector is somehow killing your components
