I think the correct answer is "Overclocking" and "Reduce CPU Clock speed" CPU is at 4.5 Ghz when normal is 3.2 Ghz. Overclocking too much can cause freezes, and this is a gaming computer so the user probably took it too far. http://blog.logicalincrements.com/2018/12/4-troubleshooting-tips-overclocking-pc/

wouldn't it be overclocking instead of device incompatibility in that case?

we don't know if there's enough thermal paste already or if the cooling system is bad or not. we only have the info thas was given to us

Overclocking, reduce clock speed. Overheating the PC would shut down. This is my final answer.

Activation of the processor's thermal control system may cause performance loss as the processor typically reduces frequency and power to prevent overheating. The maximum junction temperature limit varies per product and usually is between 100°C-110°C. This CPU is only at 80C so it is NOT overheating. The CPUs Junction point is 94C. 80 is less that 94! Junction point is effectivly the tipping oint at which the CPU is too hot and mitigation techniques are employed like reducing frequency and power.

ok bro but the cpu is at 80 degs while idle in the bios, what do you think is gonna happen once it starts calculating?

Reading this again, at first I thought overheating, but the answer really is overclocking. First, you can see it's way over the base clock. Second, you can see that despite that, the temp is 80C, which would be within tolerance. Lastly, and most importantly, the computer LOCKS UP. Most CPUs nowadays have overheating protection and the computer would likely and plainly just shut down, or the CPU would be throttled to protect it, and clearly this CPU is not some old thing. The locking is up is typical of overclocking and happens when you're past what the CPU can actually take. Same for RAM, things just freeze. "Overclocking" and "Reduce CPU Clock speed"

Cause: Overheating Resolution: Replace thermal paste Explanation: The issue of the computer locking up within a few minutes of startup suggests that the system may be experiencing overheating. The CPU temperature reaching 80°C and the high-power components like the CPU and GPU indicate a potential thermal issue. By replacing the thermal paste between the CPU and the liquid cooling unit, the technician can ensure better heat transfer, which should help alleviate the overheating problem and prevent system lockups.

Comptia is against Overclocking, so likely they will use Overclocking as an example of an error

Because its a GAMING Computer , i would say overclocking and lower clock speed. I dont think its overheating because the junction speed is 94C , just above the 80C the pc is currently running at

They are overclocking but thats more likely to lead to overhearting. They need a better cooling system, therefore a larger Radiator. Google says: "The number one problem caused by overclocking the CPU is overheating. Overheating will cause your CPU to fail, and can also cause permanent damage. Overclocking will sometimes introduce an element of sporadic performance in your computer." In fairness dropping the CPU speed would also work!

I have seen this issue in person, and the answer is overheating, and reapply thermal paste. 80 C is way too hot for a CPU, and should be around 30-40 in most systems. If the user forgot to apply thermal paste, or applied it improperly, the system will run for a little while and then freeze/shutdown. The issue I experiencded in my case is that the user "cleaned" their computer and wiped off the thermal paste thinking it was gunk.

30 degs under load while gaming? maybe with an expensive cooling option but not with the little cpu cooling in this example

Chat GPT answer- Given the information provided about the customer's gaming computer and the potential causes and resolutions, here's a likely cause and resolution for the issue: Cause: Overheating Resolution: Install a Larger Radiator

Explanation: The liquid cooling system with a 40W power rating may not be providing sufficient cooling capacity for the CPU, especially considering that the CPU has a high TDP (Thermal Design Power) of 165W and a junction temperature of 94°C. The symptoms of the system locking up after a few minutes of use could be due to the CPU overheating. Installing a larger radiator for the liquid cooling system can help dissipate heat more effectively, ensuring that the CPU operates within safe temperature limits. This should resolve the overheating issue and prevent the system from locking up. It's also essential to ensure that the liquid cooling system is correctly installed, with good contact between the CPU and the cooling block, and that the thermal paste is applied correctly. Additionally, monitoring CPU temperatures during operation is crucial to confirm that overheating was indeed the cause of the lockups and to verify that the larger radiator resolves the issue.

I would say it is overheating. With a resolution of replace thermal paste. If the system is at 94C at boot there is an issue. Although at these specs the user should not be allowed to build a computer again.

Ok i did an extensive research on this question and it is not OVERCLOCKING because the base clocking for both Video(GPU) and CPU is within Range .. Now here is the catch ... The Junction Temperature is generated by semiconductors on the motherboard that works closely with the CPUs and both shows Temperature is higher than normal which leads to lock shutdowns. My answers Component Incompatibility (to be logical, not enough thermal paste or maybe Video card incompatibility leads to overheating) during the build and lower clock speed to 3.80 to get a throughput (TURBO BOOST) of 4.5 when needed.
