Question Flash of color lines on screen please help!

[GageLA]

I've been having random flash of colored lines on one portion of my display thats last a fraction of a second and it's very random it might only do it 1-3 times when using the pc or could be doing it 3-20 times, does it when sitting on desktop, playing games, surfing the web. I've tried different monitors, new graphics card, new power supply, new display cables and a fresh windows install and nothing has helped.

Did you try a new power supply cable for the monitor/monitors? try wiggling it to see if it causes the flashing lines.

I have tried that

I dont know what monitor your are using but it most likely has a power supply that plugs into it, then a power cable that plugs into the power supply and into your houses power sockets.

when you said you tried a new "power supply" i assumed the one for the PC.

Power supply is built into the monitor I've bought a new monitor already and still does it. And I tried a new power supply for my pc

it seems like the only things left to rule out are the rest of your PC components and the houses electrical sockets that you plug your system into, i'm not sure if the motherboard, cpu or memory can even cause this kind problems, try moving your PC to a socket that uses a different electrical breaker, are you using a surge protector or a power splitter?

Using a surge protector

Using a surge protector

try connecting your PC and monitor do a completely different power socket without the surge protector, like your neighbor or friends house, i know it seems impractical, but if the problem persists after you do that, then it must be a problem within your system, bad surge protectors can cause voltage fluctuations, electrical problems within your house can also cause voltage fluctuations.
