Device fails to load BIOS after installation
Power source: Corsair rm750e Motherboard: MAG B650 tomahawk WiFi AIO: Ls520 se CPU: ryzen 5 7600x Graphics: sapphire pulse Radeon Rx 7800 SSD: samsung 990 pro 2t ssd RAM: g skill trident ram z5 ddr5 (2 x 16gb) Situation: This machine has been running for over two years without issues. Recently, boot times have increased significantly—from about 5 to 10 minutes, and more recently it took over 4 hours. I thought it was normal at first, but now it’s stuck. After a fresh Windows install, I powered down the PC to perform a BIOS update. It hasn’t started since then. The fans are running and display red and yellow indicators, but nothing appears on the screen. I disconnected the RAM completely, reinstalled it one by one, double-checked the CPU placement, and even removed the GPU and CMOS. All cables were reconnected. I attempted to boot using an external SSD with Windows installer, but it still didn’t work after 30 minutes. Lights and fans are active, yet keyboard and mouse remain unresponsive. I’ve noticed the red light means CPU issues and yellow indicates RAM problems. I tried removing the SSD and using a USB drive with installation media, but nothing changed.
The main components to check are your boot drive, RAM, CPU, and BIOS. Start by resetting the CMOS memory—this is especially useful after updating your BIOS. It’s simple and free. If the computer doesn’t start, disconnect the boot drive to simplify troubleshooting. When the system boots into the BIOS without a drive, inspect the RAM for dust or debris, ensuring contacts are clean and free of dirt. Check the CPU sockets for any bent pins and handle the CPU and cooler with care, including applying thermal paste. If issues persist, consider testing the components on another machine, particularly focusing on RAM and CPU. If the BIOS is corrupted, you might try re-flashing it using Qflash (as indicated on MSI boards). This process doesn’t require a CPU or RAM to update the BIOS. Good luck!
To reset the CMOS, turn off the computer and disconnect it from the power source. If your motherboard has a reset button near the PSU, press it. Alternatively, you can discharge the CMOS jumper on the motherboard. Refer to your manual for specific instructions: https://www.manualslib.com/manual/327065...tting-bios
You're unsure about the next steps since you're testing on a brother's PC with the same motherboard. It means you need to confirm whether you should replace the motherboard or not.
It seems like the setup might not be ideal. Trying another power supply unit could help confirm things. Ultimately, you should choose a system that starts up with your CPU and RAM working properly. I just realized something important—have you checked if the SSD firmware is up to date? There were reports of early wear on some high-end Samsung SSDs, which could explain why your computer slowed down. You can search for "990 pro degradation" online for more details.
Discovered it was the CPU after trying it on a functional motherboard—it wouldn’t work—but confirmed it worked once the correct one was installed. Thank you!
