Device shut down, emitting a strong odor.
I was about to play some games with friends when the PC suddenly stopped working. It cut off completely and gave off a burning odor, similar to solder. My CPU (i5 9600k) had been struggling with overheating for some time. The machine I built seven years ago needed its CPU and motherboard replaced in 2019. Everything else, like the Corsair RM750 PSU, was still original. After trying to restart, all USB devices powered on along with the GPU and fans, but no output appeared on the monitors. When the PC shut down, the Corsair AIO light turned red, suggesting a possible CPU issue. I’m not sure about any beeps, and since it’s unplugged now, it shouldn’t start a fire. However, if the PSU was the problem, could it cause a fire when turned back on? I’m a bit worried but haven’t been very active with PCs lately. I might just clean the dust out and see how it goes, possibly needing a new CPU. Any suggestions or thoughts? Is there a risk of damaging the house? =D
It's a good idea to be cautious while working on your PC. Avoid spraying any files while the device is powered down.
This occurs when you rapidly spin an unplugged fan, producing electricity.
I believe it was a can of air. Just examine the extended nozzle. If it were hair spray, the residue inside the case would also have ignited and burned for a bit longer. It seems more likely a fine dust was involved, forming an ideal fuel/air blend, with the fan producing sparking embers (like @SimplyChunk suggested).
Key tip: when using compressed air to clean fans, avoid spinning them. They may rotate much more than intended and destroy themselves. If linked to other parts, force power through the device, which can also harm it.
Great to hear! The hairspray comment was probably just a joke.
