Alt + Tab reboots PC

After updating Adrenalin (24.12.1), the computer occasionally restarts when alt-tabbing.

In the Event Viewer, the following error is logged:

  • A fatal hardware error has occurred.
  • Reporting component: Processor core
  • Error source: Machine Check Exception
  • Error type: Cache Hierarchy Error
  • Processor APIC ID: 3

In the past, a complete reinstallation of drivers resolved the issue, but this time it doesn’t help.

Initially, I suspected a hardware problem with the PC components, but stress tests using FurMark, Prime95, and MemTest revealed no issues.

PC Configuration:

  • CPU: Ryzen 5 5600
  • GPU: RX 7700 XT
  • Motherboard: ASUS TUF B450M-PRO Gaming
  • RAM: Corsair Vengeance 2x8GB
  • SSDs: WD Green 512GB and Samsung 980 1TB
  • PSU: Thermaltake 650W Gold

I don’t remember which driver version I was using previously, so if the issue cannot be resolved for this version, I would appreciate a recommendation for an optimal driver version to install.

First you might have a under powered PSU for your RX 7700XT. According to AMD that GPU needs a minimum PSU of 700 watts.

 

Try disabling in Radeon Settings the Hot Key feature and see if that stops the PC from shutting down.

 

I would stress test your CPU and GPU using OCCT  plus stress testing the PSU.

 

See if the PC crashes in any of those 3 stress tests. OCCT is good for checking PC stability. During the testing keep an eye on Temperatures, Fan Speeds, and PSU Outputs.

I ran tests in OCCT, and everything went well. The CPU reached a maximum temperature of 90°C and a voltage of 70 watts. The GPU had a temperature of 71°C and a voltage of 200 watts.

As per your advice, I disabled hotkeys in the Adrenalin settings. I also adjusted the settings to reduce the GPU's power consumption. However, before conducting the tests, the computer rebooted again, even though only the browser and Discord were open.

This might not be relevant, but it seems that every time the computer rebooted, it happened when I switched to Discord.
