Is your new PC setup causing you a lot of concern?
Is your new PC setup causing you a lot of concern?
Was called in and now I'm here.
This clearly indicates a PSU problem.
However, it seems more likely a MoBo or GPU issue.
It might be that testing with a second PSU caused a failure. Since a failing PSU usually leads to MoBo being the first to fail, followed by GPU shortly after. CPU and RAM are more reliable but still not completely immune.
MSI MAG A-GL is of average quality, Tier B. For a gaming rig, a Tier A PSU would be ideal.
Examples include Seasonic Focus/Vertex/PRIME, Corsair RMx/RMi/HXi/AXi, Super Flower Leadex Gold/Platinum/Titanium.
Tier A will suffice, while Tier A+ is better.
(My three PCs are all powered by Tier A PSUs. Specifically, I have Seasonic PRIME 650 Titanium (Tier A+), Seasonic PRIME Ultra 650 Titanium (Tier A+) and Seasonic Focus PX-550 (Tier A). Detailed specs with photos are in my profile.)
Based on the symptoms, a new high-quality PSU probably won't solve your problems. As I mentioned earlier, the symptoms also suggest other issues that could be equally problematic.
If you replace the PSU with a good one and still face the same issues, then:
* Remove the GPU, connect the monitor to MoBo and check if it boots up.
If it does, the GPU is likely faulty.
If not, then CPU, MoBo, RAM or all components may be dead.
In this scenario, if you have a compatible build ready, test each part separately to identify what's failing. Otherwise, take the PC to a repair shop for diagnostics.
Thanks for the update! As mentioned before, I attempted what was suggested—using just one RAM stick and an integrated GPU instead of a dedicated one—but that didn’t resolve the problem.
However...
once I reinstalled the full setup with the dedicated GPU and the second RAM stick, everything started working properly. The main concern now is...
so, could there really be a chance that nothing is completely broken, as you suggested? Because again, I’m not sure if that matters, but the PC is functioning perfectly now. The only issue is during normal shutdowns, which is why I appreciate your time!
There might be a loose power cable somewhere. Inspect all connections carefully. However, if the PC doesn’t start after a cold boot but works otherwise, the PSU seems to be the problem. A good PSU should allow the PC to power on both during a first startup and when restarting from a soft boot. Usually, CPU, memory, and RAM function properly once the system boots. Occasionally, the CPU might still be defective, leading to various error messages after OS loads. You can test the CPU using programs such as Cinebench, Prime95, or AIDA64. For memory testing, use memtest86.

Testing frequency:
- Minimum: 1 full pass (15 tests)
- Better: 2 full passes
- Acceptable: 4 full passes
Recommended to run overnight for best results.
Time estimates:
- 8GB RAM: ~1 hour per full pass → ~4 hours for 4 passes
- 16GB RAM: ~5 hours per full pass → ~20 hours for 4 passes
- 32GB RAM: 32 full passes needed (long and not practical)
If no errors appear, RAM is likely fine. Errors suggest replacing the RAM. For thorough RAM testing, 32 passes are required (per test #7).
GPU can be checked with tools like Unigine Superposition, but MoBo testing isn’t possible.
