It was always crash to desktop without any errors or sometimes it was a stuck on loading screen with cogs spinning. Music plays and nothing happens. All of those problems gone after CPU fix I mentioned above.

There is probably more chance that your hardware fails because of a power surge from your electrical outlet than from a hard freeze because the CPU goes to 100% on all cores and you have to hold the power button. Holding down the power button cannot harm your pc, it's designed that way. Even plugging out the cable shouldn't although it's probably more risky.
Having your CPU lock up for a few seconds before you reboot won't do anything. It can absolutely sustain that and high temps as well. Now if you leave it in that state for day, that's another story but "people with a brain" wouldn't do that, right?
Modern CPUs and MOBO come with built safeguards that prevent this, so it probably wouldn't even be possible.
If you're scared for no reason, please do and don't play the game, it's that simple, but don't spread misinformation.

Even 0.1% chance is too much for an issue like this. And chances are much higher than 0.1%, although still low.

"Holding down the power button cannot harm your pc, it's designed that way." I will tell you an important rule in engineering(and life in general): "A failsafe is not a feature." In this case the power button shutdown mechanism is designed as a failsafe for situations where the OS or system becomes unresponsive. It is not intended to be the primary or routine method for shutting down a PC. Using it frequently undermines the purpose of a controlled shutdown process.

Incompleteness of shutdown process interrupts system operations, which can interrupt critical tasks leading to data corruption. Even with modern file systems, an abrupt shutdown may leave temporary files or critical system configurations in an inconsistent state, requiring repairs during the next boot.

In mechanical drives, a forced shutdown could interrupt the normal parking of the read/write head, potentially causing minor wear. While rare, repeated occurrences could increase the risk of a catastrophic "head crash", a severe mechanical failure in a HDDs that occurs when the read/write head, which hovers right above the spinning platters, comes into direct physical contact with the platter surface. Since the platters are coated with a thin magnetic material used to store data, any contact with the head can cause permanent physical damage and data loss.

For SSDs, which lack moving parts, and rely on firmware to manage data, if a forced shutdown interrupts critical internal operations (like garbage collection or wear leveling), it could result in data loss or even firmware corruption.

There is also electrostatic and capacitive effects. The key here is "Charge Imbalance". Capacitors in power circuitry store charge. A sudden shutdown might not allow for controlled discharge, which could affect components over time due to uneven stress cycles.

Another problem you might encounter is with all-in-one (AIO) liquid cooling systems. In these the pump is responsible for circulating coolant through the loop. An abrupt power cut halts the pump's operation instantly, which can leave coolant stagnant in the system. Stagnant coolant may allow air bubbles that were previously suspended in the liquid to collect in the pump or tubing. When the system restarts, these bubbles can disrupt the normal flow of the coolant, causing cavitation (tiny air pockets in the pump), which manifests as unusual sounds like gurgling, grinding, or rattling.

In some other cases where the cooler was already on its last legs, if the liquid cooler contains any sediment or impurities, sudden stops could lead to clogging in the radiator or pump, potentially resulting in noise or reduced performance. I am mentioning this because there is a person in this very thread that was talking about "weird sounds" from his cooler so when I read that I thought about what might have caused it.

There is also how this crash is (supposedly) happening in the first place: 100% CPU utilization. This happens in a spike format. A sudden spike to 100% CPU utilization generates significant heat in a short period. If the system crashes at this point, the CPU may remain hot while cooling mechanisms (fans or pumps) that should have been dissipating heat are not functioning because forcing a shutdown stops cooling systems immediately. The residual heat can cause localized overheating, particularly in the CPU die (and Voltage Regulator Modules on the motherboard). Repeated instances increase the risk of thermal degradation.

The sudden power-off may induce transient voltage fluctuations, which can harm sensitive components like the CPU, GPU, or motherboard power circuitry. These components are especially vulnerable during high load conditions.

There is also the capacitor strain: The power delivery systems on the motherboard and power supply unit (PSU) experience increased strain during peak utilization. Abrupt shutdowns can exacerbate this strain, leading to shortened component lifespan.

For air-cooled systems, fans running at high speeds during 100% CPU utilization experience mechanical stress when stopped abruptly. Over time, this can degrade fan bearings or motors.

For any component that is already on its last legs, an event that would lead to shortened component lifespan might be the finishing blow.

And remember, this is not once in a while event, these crashes happen frequently, with short intervals(if one keeps playing the game after the crash and crashes again and again and again).

I never said "use your brain" at any point. Are you sure you are not confusing people you are answering to?

That's not the problem in this thread. Although your fix is great for the other thread(s), the ones with crash to desktop and loading stuck leading to desktop crash.

This thread is about the hard crash where event viewer not even registers a problem and PC locks up until you manually shut it down via pressing the power button.

it is very reasonable to assume that your hardware will break when you force a restart because it is very unusual for a game in recent history to cause a total system malfunction.
YOU are not trustworthy for saying that this is fine

Imagine reading these posts and having some random online telling you they fixed it by reinstalling windows only for you to do the same and it not fix a single thing. LOL. There is currently still no valid fix for this issue. Unfortunately, it is best to just wait it out until GGG actually comes up with a resolution.
