PC Building

[Triks134]

Recently I purchased a new GPU to upgrade my computer. It wasn't until some time later that I noticed this problem.

The problem is that at random times small red squares (artifacts) appear on the monitor, arranged in a ladder across the monitor. At this time, the PC freezes, so I can't even move the mouse. After that, after 1-2 seconds the monitor goes out, then after about the same period of time the image returns again, but without any defects. This problem most often appears under the load on the video card, for example, in games. The video card is connected via a VGA to HDMI adapter.

The video card is not new. I want to know if the problem is due to the video card chip or not. Because artifacts do not appear all the time, but only in certain cases. 

My specifications:

OS: Windows 10, 64 bit;

CPU: Intel Pentium G2120;

GPU: AMD Radeon RX 580 2048SP;

RAM: 8Gb DDR3, 1066MHz;

Storage: HDD, 512Gb;

PSU: FinePower 400W.

It sounds to me like your video card is either overheating or not getting sufficient power from an off-brand 400 Watt PSU.  I don't think it's the monitor.  First, see if you can monitor the GPU temperature to see if it's getting above 60 C.  Then if the temperature doesn't look too bad, I would try uninstalling the current Radeon Adrenalin graphics driver and then downloading the one AMD identifies as appropriate for your older card - it won't be the current one, but they might identify one from 2022 or 2023.  If the reinstall of the graphics driver doesn't do the trick, I would consider a more powerful (and name-brand) PSU.  I wouldn't bother buying another video card until you at least replace the PSU with something closer to 600-700 watts.

That's why I'm register here, compared with Nvidia rtx  this is doing lots of artifacts , i had to disable GPU scaling, virtual super resolution because lots of artifacts and white horizontal flashing lines...
