Pc monitor flickering and green artifacts. Sign of death?

[fourosg]

Almost every time i boot up my pc my screen gets full of moving green dot and artifacts and flashes on and off. After a few minutes it gets normal again. I switched to another graphics card and the problem remains. I have an asus gtx 950 graphics card and a 6 year old samsung led monitor.
Could it be something else except faulty display?

Thanks in advance

It sounds like the monitor since the graphics card was changed.

To be absolutely certain use a different PC or media device (i.e. anything with HDMI output if you have an HDMI input on the monitor)

Unfortunately i dont have any other hdmi device nearby. Could it be any psu or motherboard problem? i have a 650 watt corsair VS psu and i use pretty heavy overclocking on cpu, but its stable 24/7 for almost 1.5 years

AFAIK these issues are solely from either a graphics card or monitor, thus if you changed the graphics card it SHOULD then suggest the monitor is at fault.

A DVD player or BluRay player would also confirm things, or even moving the PC and hooking it up to a monitor.

I don't believe a faulty video cable would account for this but I don't want to rule that out, so. In order I'm guessing:

1) monitor, or
2) video cable (unlikely), or

Nothing else?

I found the solution for my problem. It seems that there was a problem with the hdmi port, as the screen work flawlessly with DVI cable and the flickering happens only with hdmi. In the meanwhile i bought a new screen and now i have 2 27" screens side by side 😛

Glad it was sorted out.

Just FYI, there's a technique in troubleshooting called the 50/50 (or half split) method. For example, take the computer as a whole and then take the MONITOR as half and the PC as the other half (assign the CABLE to the monitor side)...

So if you hooked up the PC + different cable to another monitor/HDTV and it works you proved it's the Monitor + cable that's problematic. You then do the 50/50 thing again by swapping one of those components.

It's a bit trickier with some issues, but I do it for example with some major software issues that may or may not be software by booting a Linux distro. Network or whatever works now? Must be a software issue then and NOT hardware.
