Problems with new graphics card


#1

I recently bought a new graphics card and a number of problems started to appear occasionally under Windows 7:

  1. A green screen shows for a couple of seconds and a continuing flickering on the monitor.

  2. The monitor goes off and on every a few seconds.

  3. Sound is distorted (a scratching noise is heard from the background).

The above happen with either displayport or hdmi cable from the graphics card to the monitor. I have speakers connected to the monitor. The above don’t happen with Ionboard graphics, so I am assuming it’s not the monitor. I am using the latest drivers.

Should I return the graphics card?

Any other ideas?

Which card?

Which PSU?

Do you have only sometimes these probs and most time it works?


#3

ASRock Radeon RX560 4GB and Corsair CX430.

They don’t happen all the time and not at the same time, but they keep repeating every 1-2 days.

Hm, heard of these or similar problems with AMD Graphics and mostly with Dell monitors. Do you have one?

Can you try DVI?


#5

It’s a Samsung and it only has displayport/hdmi ports.


#6

The green screen happens with AMD Graphics if:

RAM voltage is to low (not sure whether it´s only a prob of onchip-graphics)

Old graphic driver

To high RAM/GPU-clock in the graphic card settings

Here I found a topic, but not sure if it help you

I don´t want to start a war of opinions, but I prefer Nvidia-cards, especially after trying AMD-cards

I am using the card with its default settings and I don’t stress it (other than using 3840x2160 resolution). I intentionally bought an AMD card to use FreeSync. I don’t see the topic in your reply.

Oops, sorry


#9

…could be easily the fact that the PSU is too weak for all your hardware…


#10

Nope, if it happens in idle.

The CX430 is not high end, but a stable build by CWT.


#11

IF THEN ELSE…

Nothing of that were mentioned.

From what I could find, it appears that the problems above are not with the graphics card, but with the motherboard. I got a reply in a different forum, that there is a known issue causing these problems, that happens randomly under some configurations, affecting several motherboard models of the same brand as mine. I contacted technical support, but they neither accepted that there are any known problems, nor they were willing to try reproducing them. As these do not happen very often, I can live with them for now, but one thing is for sure, I am not buying from them again.

As a system-builder for many years I can tell you it´s not that easy to find and reproduce those bugs.

There are only a few mainboard-manufacturers left with a good amount of products (Asus, Asrock, Gigabyte, MSI) and some more exotic or special ones (Biostar, EVGA, Supermicro, Fujitsu).

All of the brands I used had sometimes buggy boards, atm I only use Asus, Gigabyte and Asrock, most of their boards are OK for my use
