If you have installed a new graphics card and the symbols and other objects show shadows or striped, flickering lines , the solution is very simple!
It is possible that the graphics card is defective, but it is usually due to the weak power supply!
Even if the PC power supply has the recommended wattage that is recommended by the graphics card manufacturer, it is possible that, for example, the 12 volt connection (6-pin or 8-pin) does not deliver the required wattage!
Read in the manual for the graphics card how many watts or amps are required at the 12 volt input and compare this with the values from your power supply unit (can usually be seen on the power supply unit).
If not, use the model number of the power supply unit to look for the information on the Internet!
If it should be enough, it can still be the cause, because there may be slight deviations from the specifications for the power supply or the graphics card, the power supply should already be 20% above the required values, so to speak as a safety buffer!
It may also be that your motherboard does not support the graphics card (also has something to do with the PCI-e wattage), if there is not enough power here at the PCI-e connection, this effect will also occur!
After working on the PC for a long time, the errors become more and more annoying or more visible and the cast of shadows increases.
This is because the heat from the power supply unit also causes the power to drop by a few percent. Overloading the power supply generates more and more heat and you are in the wrong cycle.
When changing from ATI to NVIDIA or vice versa, all graphics card-specific software should also be removed, as well as the drivers of the old graphics card!
Please also note the power supply specification ATX 2.1, ATX 2.3, ATX 2.4 etc.!
