[SOLVED] Could my CPU be failing, or is it my PSU ?

[Walawe]

So, my PC keeps turning off suddenly every time I play The Witcher 3 Next Gen (it has happened three times already after around 20 minutes of gameplay). The GPU (Radeon RX 6650 XT) temperature is around 70–80 Celsius, and the CPU (Ryzen 5 5600) temperature is around 50 Celsius and never reaches 55 Celsius during gameplay. I tried troubleshooting the problem the third time it went off by removing the RAM and reinstalling it. However, after doing that, my PC wouldn't turn on when I tried to start it. The fans and GPU were running, but there was no display—just a black screen.

So, I replaced the CPU with an older one (Ryzen 5 2600, which I bought 3 years ago), and then it booted up normally. I played the game again, and after another 20-60 minutes, it ran normally, but now my CPU is experiencing bottlenecking issues but still playable at 40-60 fps. Despite this, there were no sudden shutdowns. Could my CPU be failing, or is it my PSU?

PC specs:
Motherboard: Asrock B450M HDV R4.0 (BIOS vP.10.01, 3 years old)
CPU: Ryzen 5 5600 (It came only as a tray when I bought it last month, so it might be used)
GPU: Radeon RX 6650 XT, 8GB (1 month old)
Monitor: 24-inch, 165Hz
RAM: 2x8 GB DDR4 2666MHz
PSU: Corsair CX650 (3 years old)
CPU Cooler: DeepCool AK400 WH
Storage: VenomRX M2. 2280 NVMe Gen3*4 2TB
OS: Windows 11 Pro

Also whenever I attempt to remove the Ryzen 5 5600, after taking off its air cooler, the CPU comes off with the cooler and sticks to it. However, when I try the same process with the Ryzen 5 2600, the CPU doesn't come off with the cooler; instead, it remains in place on the CPU socket of the motherboard, unlike the Ryzen 5 5600, which comes off with the cooler. And this is consistently happening.

Welcome to the forums, newcomer!

Motherboard: Asrock B450M HDV R4.0 (BIOS up to date, 3 years old)
What BIOS version are you currently on for your motherboard? I would try and reflash the BIOS , clear the CMOS and then see if the issue persists. One other thing you ca do is to drop in your Ryzen 5 5600 onto a known working motherboard with the right BIOS on a donor platform and see if the issue is reciprocated there as well.

If you think the PSU is at fault, source(borrow, not buy) a donor PSU that's reliably built and with 550W of power at the entire system's disposal, from a friend or neighbor.

A three year old PSU is a likely suspect.

Look in Reliablity History/Monitor and Event Viewer for error codes, warnings, and even informational actions being captured just before or at the time of the "turn-offs", crashes, black screens, etc..

Reliability History is much more end user friendly and provides a time line format that can reveal patterns. So start with Reliability History.

Event Viewer requires more time and effort to navigate and understand.

Any given entries can be clicked for more details. The details may or may not be helpful.

Increasing numbers of errors and varying errors are symptomatic of a failing or problematic PSU.

Take a look. Take your time looking and do not jump to any immediate conclusions.

Note error codes and post accordingly.

Thank you for the warm welcome! I'm excited to be here.

Currently, I'm using version P10.01. So, what I did again was I replaced the CMOS with a new one and reinstalled the Ryzen 5 5600. Guess what? It ran normally again. However, when I tried to run the game, after a few seconds, the screen just froze, and then the display went off. The CPU was still running, so I restarted it. The PC was running, but there was no display—just a black screen like before. And yes, I have checked the monitor, and there is no issue.

Hmm, I thought the PSU would last for 5-10 years, especially with a reliable brand like Corsair, which is what I'm using right now.

Yesterday, I tried checking the event viewer, but that was when my PC could still be turned on after shutting down. From the previous event viewer, I checked the current log, and it shows eventID 6008 and 41 (Kernel Power). I attempted to solve it by adjusting my power settings (based on a YouTube video) but was unsuccessful. However, this time, my PC really couldn't be turned on again, which is why I posted the thread above.
