No, dead integrated GPU does not harm the CPU.
Your integrated graphics might affect CPU performance, but they shouldn't cause the CPU to stop working. They could slightly impact processing speed depending on the load. For your CPU model (Intel i5 4590S), this is generally safe unless you have a known issue with power delivery or overheating.
It might not be your GPU at all; just clean the ports and it should resolve any graphics problems. You're unsure if the GPU can fail independently, so assume both will stop together. You could try a low-end GPU with a budget price to test.
What concerns me is the possibility of failure. Honestly, that’s not really how such devices function. Intel’s integrated GPU has always been quite average at best. (Although they’ve improved recently, it’s still not suitable for an 8-year-old). I suspect you’re dealing with other problems that might not be solvable just by adjusting software. In short, just like a doctor would advise someone without medical training, DO NOT self-diagnose! This also applies to computers—if you don’t understand how they work, you shouldn’t expect to predict the outcome.
Thanks for the updates. I thought my IGPU would fail since I began noticing artifacts during gameplay and even at startup. Colors were off, objects distorted or blinking erratically—like a disco effect. Everything else in the browser works fine, just these strange visual glitches. Temperatures are normal too. I've attached some images showing what's happening.
Have you considered switching to another monitor or cable? It might be one of them. Alternatively, a failing PSU could be the issue, struggling to maintain required power levels. This is less common than the first two possibilities, but not impossible. In my view, those three factors are more likely than hardware failure, though anything is still possible.
I've got two monitors working identically, but it's still happening on both sides. I tried changing cables and ports, but the issue persists. It seems like the PSU might be the culprit, especially since it's a Lenovo OEM unit that's quite old. I'm planning to replace it with a new one once the graphics card is installed. Thanks for your assistance!
