The System isn't sending a POST, not even to the BIOS?
The System isn't sending a POST, not even to the BIOS?
Details
Motherboard: Msi Z650 Edge WiFi
Processor: Ryzen 7900X
Graphics: Asus 4070 Ti
CPU cooler: Corsair H115i
Memory: Acer Predator Pallas II 6000mhz cl30
Storage: Samsung SSD
Power supply: Corsair RM750e (2 years old)
Operating system: Windows 10
I connected all components, pressed power, and launched Windows. Default settings appeared correctly, and everything functioned properly. After downloading chipset drivers, I spent some time browsing and then the updates finished. Restarting the PC activated Expo mode. However, upon restarting again, it failed to boot and displayed an error stating "Over current has been detected on your USB device!" The system automatically shut down after 15 seconds.
I repeated the process multiple times, but the issue persisted. After disconnecting all I/O connections, removing the USB and USB 3.0 ports, and even swapping out the internal USB and memory cards, the error remained unchanged.
Searching online, I found discussions on Reddit and Google where others resolved similar problems by performing a BIOS update. I obtained the latest BIOS from another computer and applied it to my motherboard. The flashing succeeded, and the PC restarted without errors.
However, the system still failed to boot normally. It would only power on once before entering an endless loop in Windows. After several attempts, I encountered the same display sequence repeatedly.
I attempted the following steps:
- Updating BIOS versions
- Clearing CMOS
- Testing with a single stick in all slots
- Deleting CMOS without RAM or CPU
- Reinstalling the CPU
- Checking for bent pins on the CPU
- Inspecting the motherboard for damage or cross-connections
Despite these efforts, the issue persisted.
Later, I visited a local repair shop where a technician examined my CPU and RAM on a different motherboard. Everything functioned correctly. This led me to believe the problem lay with the motherboard itself. The latest BIOS caused a DRAM error, while the older one triggered an "over current" warning on the USB device. The technician recommended visiting Msi for assistance. I planned to do so but would have to wait two days due to upcoming Sunday and a festival that day, after which the service center might be closed.
Currently, my PC is non-functional. I’m seeking help from others who may have resolved this issue. I’ve tried everything available online, but if anyone found a solution to bypass this problem, your support would be greatly appreciated.

Are you using this motherboard? If yes,
the rear panel of your board features a BIOS flash button. Follow the latest BIOS instructions in the video to update it;

Once confirmed the BIOS update was successful, turn off the system and reset the CMOS by unplugging from power and display, then remove the CMOS battery. Hold the power button for 30 seconds to discharge any remaining charge. Replace the battery after 30 minutes.

I also faced this problem when updating to the newest BIOS—black screen and I don’t boot past it. This version works perfectly and boots much faster than any other BIOS I’ve tried. The issue needs serious fixing from Microsoft with the latest updates, since we can’t upgrade CPUs without a working BIOS. Trust me, download 7E10v162023-06-01; it should work on the first boot. It took me five days to test all the BIOS versions and most of them caused black screens or slow boot times after the logo.
