Problem with computers shutting down after 5 minutes
Problem with computers shutting down after 5 minutes
Hello friends, I’m facing an issue I don’t understand and need some advice. At work we have three identical computers. Last week on Monday the first one stopped working. On Tuesday the second, and on Wednesday the third. They freeze after about five minutes. I’ve tried many things—running diagnostics, checking drivers, reinstalling GPU software, changing BIOS or secure boot settings. It worked for a week. Now after a week, two of them are freezing again after five minutes. I’m hoping to hear from someone soon about the third one. Do you think there’s something specific I should know or how to fix this?

When sharing a troubleshooting thread, it's standard to provide your full system specifications. Please list the details as follows:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Include the age of the PSU along with its make and model.
BIOS version for your motherboard at this time.
To add, are you the IT professional on the team?
I just formatted them and reinstalled Windows.
Where did you obtain the OS installer?
Hello, thank you for your response and for bringing up the details. All three systems are identical: CPU I3-4170 @3.70GHz, stock cooler, motherboard Asrock H81M-DGS R2.0, 16GB DDR3 at 1600MHz RAM, Samsung 870 EVO SSD with 500GB capacity, AMD Radeon R7240 2GD3 L GPU, power supply LCPower LC420A V2.3 (350W 80Plus), ATX midi-tower LC-Power 7024B, operating system Windows 11/10.0.26100, and the monitor I currently use is an LG 22MP47D. I’m the IT specialist here, but this setup has been quite a challenge. The OS came from a verified, licensed source within our organization. Appreciate any guidance you can offer!
I observe that you are running Windows 11 and I’m unsure if this is the reason for your issue, but I recently learned that a second Tuesday update led to numerous problems. One person mentioned they had to send 10 people home since most of their machines wouldn’t even start. Their article might be relevant, though it’s unclear.

It seems unusual that this happened again after a clean reinstall, what antivirus software do you use? I see ESET, which includes a network inspector.
Will the systems start in Safe Mode?
Can you access Reliability History/Monitor and Event Viewer to see error codes, warnings, and events?
Additionally, how was confirmation that the OS came from an official and properly licensed source through our company achieved?
Even companies and "official sources" can be deceived. Please check the serial numbers, license keys, etc.
