Intermittent GPU Hardware Faults Triggering Random Screen Artifacts

It seems your graphics card has a VRAM issue that points to a possible defect. But check first if the card's temperature are below the specs. It is strange to see this in Gaming and non-gaming mode. If you overclock it to high and the temperature is above specs; that can damage your card. Also check what this card normally draws (Watt) add this figure to what your system is drawing. If your PSU is below that figure you have to buy a higher Wattage PSU. On average 850W Gold will be enough unless you have a RTX5090 card that draws more power Some needs a 1200W PSU. If you have 850 PSU and it occurs also in non-gaming mode my suspicion goes to the videocard. Make sure you don't overclock it. (In non gaming mode there is no need to do so) Use HWMonitor to check the temperatures. If they are normal then your graphics card is defective. You can have have some artifacts (not as heavy as these!) maybe but in normal non-gaming mode these should not occur.....
