Question PC Crashing After 30 Minutes of Playing Demanding Games – Need Help Diagnosing the Issue

[notead8]

Hello, good morning/evening,

For about 5-6 months now, I've been having a problem: my PC crashes after 30 minutes of playing demanding games. I’ve already tried fixing the issue. At first, my CPU would reach 100 degrees (during heavy games), so I changed the thermal paste and CPU cooler, bringing the temperature down to 60/70 degrees. I also tried replacing the power supply, but that didn’t work either. I regularly check my temperatures, and they are not alarming, staying at 60/70 degrees for the CPU when running games on ultra settings.

I also checked the Event Viewer, and it always shows the same thing before the crash:
The thermal zone ACPI _TZ.TZ00 has been enumerated, which results in a critical error.

Here’s my configuration:

• Motherboard: Gigabyte Z390 UD
• Processor: Intel Core i7-9700KF
• GPU: Gigabyte RTX 3080
• Cooler: Be Quiet Dark Rock 5
• Power Supply: Antec 750W Gold

Please note that I’ve had this PC for 6 years.

Thank you for your help, have a great day/evening!

Failure after a time smacks of a temperature issue.
There are many cpu temperatures. You might be looking at the package temperature.
Run hwmonitor when under load and look explicitly at the max individual core temperatures

That ACPI thing is a functionality and does not help much...

How old is that PSU and what is the variant?
Is there any kind of OC or UC executed on this machine?
Have you tried fresh Win installation?
Did you update/reflash your BIOS?
Did you turn off fast boot?
Did you reinstall your drivers?
Did you run SFC/DISM commands?
Did you run memory diagnostics?

My power supply is an Antec 750W 80 Plus Gold. I've had it for 5 years. Note that I already had it replaced with the same model, but it didn't work, so I got a refund.

No, there is no overclocking (OC) or underclocking (UC) applied to this machine.
No, I haven't tried a fresh Windows installation yet.
Yes, I updated/reflashed the BIOS about a month ago.
Yes, I turned off Fast Boot.
Yes, I reinstalled my drivers.
Yes, I ran the SFC/DISM commands.
Yes, I ran a memory diagnostic.

I ran HWMonitor while playing Escape from Tarkov and each core's temperatures ranged between 40°C and 57°C

The quickest and fastest way to figure out where to really start to look for the real problem is have a spare SSD and keep it around like you would a tool.

Spend about 35.00 on a SSD and for testing un plug your working "C" drive and install a clean copy of windows on the spare SSD , all drivers and a few games. If you now run fine it point to your old install of Windows . If it still acts weird than we dig into the hardware side.

I can't tell you how many computers I have been given that the original owner was up the wall and hated it and called it every name in the book complaining about every day it sucked and let them down . 98% of the time it was WINDOWS.

What specific model number is the PSU? Details matter.
