Pc requires several bootloaders to begin functioning
Hi everyone, I've been experiencing some unusual problems with my PC recently.
When I power it on, everything functions properly at first, but after a few minutes (between 1 and 5 minutes) the screen becomes black and forces me to shut it down using the case's button. After restarting, only the keyboard light appears (not the usual one) and remains active until the system restarts on its own or is manually forced.
On the motherboard, the VGA indicator lights up after a normal check.
Occasionally, it seems the system will boot successfully, but then the keyboard and mouse lights appear normally, followed by an unexpected shutdown and restart. It takes some time for everything to work correctly again, but once it starts, the computer operates smoothly even during intensive tasks.
Below are my current specifications:
* CPU: i5-12600
* GPU: Radeon RX 6700 XT 12GB GDDR6 Power Color Red Devil
* SSD: KIOXIA Exceria 1TB NVMe
* RAM: Corsair Vengeance 32GB DDR4 3600MHz
* Motherboard: MSI MAG B660M Mortar DDR
* PSU: MSI MPG A850GF 850W
What actions I've taken so far:
* Updated BIOS
* Installed new GPU drivers
* Replaced RAM
* Swapped the power outlet (assumed issue was with an extension cord)
•Signal strength inconsistent with expected levels
•Limited performance under abrupt load changes
•Poor power factor characteristics
•Underperforms by more than 70% at reduced load
•Unstable output when subjected to stress
•Ineffective efficiency in 5VSB configuration
for your psu, the negative information

Some quick suggestions to consider.
Since your CPU includes built-in graphics, try removing the 6700XT and connecting it directly to the motherboard. Check if the system boots up. This could indicate a power supply problem or a graphics card issue.
If you have extra money, consider buying a basic power supply tester on Amazon. They aren’t very precise but can help identify problems like faulty rails before replacing your PSU.
When testing hardware, do you have another machine or friends who don’t mind inspecting components such as the GPU?
Also, it might be useful to take the parts out of the case and build a breadboard setup on the motherboard tray or a table. Verify all connections are secure and that no pins are damaged. Also, ensure standoffs are correctly positioned, avoiding metal debris.
