RESOLVED plase help getting green flimering pixels on my screen? gainward 780gtx whit pictures of the problem

post #1 of 8
Thread Starter 
not that long ago i bought a 780 and suddenly i got green pixels in my screen they come and go one day they are there the next they are gone and some days it is worse, i like talked to the place i bought the card and they said something might be wrong whit my card at first i thought so aswell.
i did try and change the hdmi cable tried to change monitor and did all the basic stuff even tried to change pciE port.
but when i already packt my card and was ready to ship it away i put in a old 620 card that i have used before just for dedicated physicx i got the green pixeles there aswell. now i aint so shure what it is since i get it on both graphic cards the 620 might be damaged since i change the cooling block on it a long time ago and it is like 2-4 years old but. but what are the chance for having the exact same problem on both cards. i really need some help here before i send back my card if it aint the card there is no point in sending it back.
il add a few pictures below
and on nvida control panel you have something called power management i had set it on perfer maximum performance like i always do innsted of adaptiv and that made the problem worse. but after i tokk it off the problem decreased it is still there sometimes but less ofter when it was on maximum performance it went like realy bad,

any clue to what it can be?

my specs are
Mainboard asus maximus vi
Ram corsair dominator platinum 2666
psu Chieftec 1200w
grafick card gainward 780
grafic card 2 msi 620
ssd samsung ssd 840pro





It was the Tv that was gone bad aswell as the other old monitor i tried out biggrin.gif

Do you have an extra monitor to confirm it is the card and not the monitor itself?
What about drivers?
Finally, your PSU might be in question as well. Which version of the 1200w do you have? Nitro or the Super Series?

Well if your PSU isn't providing the power it has to, please see past the fact that it's a 1200w, then it might be an issue. I'm no expert on PSUs so I won't go into details that I know nothing about. I couldn't find any reviews on the 1200W Nitro, only the 750W and that received a good review from KitGuru.
Your cable can also be an issue, especially following what you said with the disconnect and reconnect.
Do you have any way of trying out a different monitor and a different cable? It could be an old 1024x768 monitor even. It's only in order to eliminate your TV from the equation.

i am no exspert my self on a psu but iv never seen or heard off a psu that cuses a problem like this,
but the wird ting is the 620 dose not use cable only power from the mainboard witch makes it kinda wird. like the 620 barly use and power tho. and it still gets the same problem
iv tried changing the cable and iv tried whit another monitor. iv seen alot of wird stuff when it comes to computers but nothing like this.
i was so shure it was the gpu that was faulty until i put the 620 in and got the same problem but my psu i probaly 3-5 years old so i guse it is time to change it. i just never knew that a psu could make this kinda issu. iv would have tought the psu would shutdown or someting if the psu couldent hadle it. and when i think about it my computer like starts upp for a 1-3 sec then turn back of then back on and it dose that 1-3 times every time i start my computer. but as i said i am no exspert on psu nither iv seen like the restart of the psu problem before and that was on a asus rampage 3 exstreme but that was due to 2 faulty ram slots.

To me the final part is trying a different PSU, if necessary, cut down on your components if you do not have a large enough unit available.

Chieftec 1200w, now that sounds like a no-name brand to me. (Correct me if i'm wrong). I'm thinking of a dying PSU, depending on the age, or if could be even that it's not that good of quality.

I've heard 12V rails on some of these PSU's begin to deteriorate after a year.

Yeah i'm pretty sure it's the PSU because, that graphics glitching like that may be because the power supply is not delivering a stable amount of power into the GPU, I think the 6x 8x PCI-E power plug connectors run under the 12V rails so there might be the issue there, try testing another PSU e.g borrowing off a friend or a spare one.
