49 is quite high for being idle in BIOS. You should ideally be in the low 30s, possibly even the high 20s. It seems likely it's overheating when you apply a load. It might be worth reapplying thermal paste to your cooler. What cooler are you using?
The issue is that I can run the Windows 11 installer smoothly on the initial screen without problems. However, if I don't format the disk or allocate space by creating a partition, the installer crashes during execution. The Windows 10 installer no longer launches on my PC.
Mediocre performance PSU rated as Tier B.
PSU specifications can be found in the attached document: https://docs.google.com/spreadsheet...JW...1973454078
For a gaming setup, a Tier A unit is recommended.
Tier A models are suitable; Tier A+ is even better.
It seems your PSU might have contributed to hardware issues you're facing now.
Upgrading to a higher quality PSU would be advisable.
Hardware failures can occur without obvious causes. Simply adjusting BIOS settings like enabling CSM isn't likely resolving the problem. Clearing CMOS and restoring default BIOS settings usually fixes such cases. However, since that didn't work, the issue appears more serious. It might have coincided with enabling CSM.
"Idle" mode doesn’t significantly engage CPU compute power, but booting the OS raises the CPU workload, which can cause instability if it becomes unstable.
Consider checking if your CPU operates correctly. (As mentioned in my first message.)
There’s no universal ideal idle temperature—values vary based on ambient conditions, cooling methods, fan speeds, and dust levels.
That’s why component reviews rarely list idle temperatures; they focus on performance under load.
For example, the R7 5800X idle temperature chart is available here: https://www.techpowerup.com/review/amd-r...0x/20.html
Please note: Ambient temperatures always set the baseline. Idle temperatures are irrelevant because even the best cooling can’t maintain them.
Low idle temps aren’t important since any cooler can keep CPU/GPU close to ambient levels. What truly matters is how well the system handles load, reflecting the balance between cooling performance and temperature goals.
In my Skylake build (with detailed specs and photos), current idle readings are:
- 27.2°C – ambient
- 30°C – CPU (i5-6600K)
- 42.7°C – GPU (GTX 1660 Ti)
- 41°C – MoBo chipset (Z170)
- 49°C – OS drive (970 Evo Plus 2TB)
- 35°C – OS backup drive (960 Evo 500GB)
- 33°C – data drive (870 Evo 2TB)
- 36°C – data backup drive (MX500 1TB)
These figures won’t help others due to differences in environment, components, and airflow.
There isn't much hardware-related problem here. You've already tried using a second RAM module, so it can be ruled out. That means CPU and motherboard are likely the causes. Motherboard alone lacks a processing unit, which makes it unstable. However, the CPU does have one. Possible issues could involve the CPU, motherboard, GPU, or power supply unit. Since all four are required for normal PC operation, you should consider replacing them. To check each, use a compatible second system to test the CPU and GPU. The power supply should not be tested because a faulty PSU could damage both the second system and your main PC. If you can't get a second system, a local repair shop can handle the replacement.
R7 5800X reaches a maximum temperature of 90°C, and as long as the CPU doesn't hit those levels, it remains safe. Additionally, this processor can maintain idle temperatures up to around 65°C, which varies based on the hardware and software setup.
On Reddit discussions:
- One user shared a link about idle temperatures not affecting overheating (https://www.reddit.com/r/Amd/comments/jo...dle_temps/)
- Another provided a comparison showing R7 5800X stays cool under load (https://www.reddit.com/r/PcBuild/comment..._rate_the/)
The original poster emphasized that idle temperatures are irrelevant, only load temperatures count. They mentioned having a high-quality cooler with a 41°C temperature difference, giving ample cooling capacity.
They also noted that compared to other CPUs of the same generation, R7 5800X stays at 75°C under load, 67°C under load for R9 5900X, and 59°C for R5 5600X—showing a 16°C difference versus the R5 5600X.
No further evidence was found about an "ideal idle temperature" for this model, aside from personal statements.
Let me address your question about what would happen if overheating were the cause. What would the system behavior be? I’ll answer based on what you’re trying to understand.
As soon as a load was applied, the CPU temperature would rise sharply and the system would shut down. This matches what’s observed here.
I’m not claiming overheating is the only factor, but it could definitely play a role. Before making major changes, I’d suggest starting with basic troubleshooting steps.
If you think normal idle temperatures are acceptable and higher than expected loads also indicate high temps, we can agree on that perspective.
