PC is experiencing frequent crashes or freezing and does not respond to shutdown requests.
Hi everyone,
Yesterday my computer froze completely and I had to keep pressing the power button until it shut down. Once I reopened Windows, the CPU was behaving oddly—running at 0.54 GHz and not increasing further—which led to significant lag and freezing. After several attempts, I managed to fix it by updating and resetting the BIOS. But today I experienced two more complete freezes: the first time the screen went all black while the PC remained on, and the second time I had to turn off the machine using the power switch on the PSU to cut power entirely. Unfortunately, my PC has frozen again, and the power button isn’t working at all this time.
Could anyone help identify what might be causing these issues? Could it be related to a failing PSU, a motherboard problem, or something else entirely?
It might be worth noting that the first crash happened when I was playing a game, and the second time it was just while watching YouTube videos.
Here are my system details:
- Motherboard: ASUS ROG Crosshair VIII HERO
- CPU: AMD Ryzen 5950x
- GPU: RTX 4080
- PSU: Corsair RM850
- RAM: 32GB G.SKILL Trident Z RGB
- AIO: Corsair H150I PRO XT
I’ve tried the following troubleshooting steps:
- Running the sfc /scannow command in the terminal to check for Windows errors (some corrupt files were found and repaired).
- Checking NVME drives for errors (no issues detected).
- Testing the AIO to ensure it’s functioning properly (no problems observed).
- Performing memory diagnostics via Windows tool (will update if any issues are found).
Please let me know if you have any suggestions or need more details.
Thanks.
For clarity, what BIOS version is installed on your motherboard? How recent is the power supply unit in your system? Did you reset the CMOS after confirming your BIOS was updated to the newest release? Which operating system are you using? You can identify your PSU by obtaining a known-good unit and testing it before powering up your setup. If it works fine, the PSU was likely the issue.
I'm using the newest BIOS for my motherboard, version 4805. It's likely the oldest part of my PC, possibly more than five years old. I updated the BIOS with the EZ flash tool in ASUS AI Suite 3, though it might not have been completely automatic. I'm currently running Windows 11.
Was diese Konfiguration mit einem neuen Windows-Update begleitet?
Laden Sie und starten Sie memtest86 hoch. Keine weiteren als null Fehler sind besorgniserregend.
This is the harsh truth about modern computers—so many problems can occur and the chance of getting expert assistance is very low. I would suggest starting by replacing the RAM and ensuring the CPU cooler is properly installed. It might be worth trying a different power supply unit. Perhaps avoid RGB components since they’ve affected system stability before. Keep the initial RAM speed as it came out of the box, as changing it appears to lead to issues.
But I believe the main problem lies in a deeper incompatibility or failure with the motherboard and its components, making it impossible to fix on your own. You may need to begin again with another brand and model of motherboard.
Does this refer to the PC build? I've had several years with some components (possibly the PSU is the oldest), and I just installed a new Windows version since I wasn't sure if Windows was the cause. The freezing and crashes are still happening, so it seems hardware-related. I ran a memory test on OCCT before and it didn't show any issues, but I'll try memtest86 too. I'm not sure if my memory is the problem because it's one of the newer parts, but I'll check if memtest catches anything.
