My PC was bricked and it won’t turn on properly, but before it happened, I installed Windows 11 via Windows 10 update to Win 11 without updating the BIOS. My MOBO is MSI MAG B550M BAZOOKA.

Note: I only messed with the TPM and Secure Boot and nothing more. I also didn’t update the BIOS before updating to Windows 11 and this may be the culprit of my corrupted BIOS.

So the current state of my PC now are:
  • - When you turn it on, the CPU fan will spin, the case fan will spin a little, about 1/4 of a full spin, and the GPU fan won’t spin.
  • - After a minute or so, the case fan will now spin but the GPU fan still won’t.
  • - The CPU debug LED stuck in white, but no display on my monitor (No signal detected)

The previous state were:
  • I can still enter the BIOS and enter Windows OS after about 5 minutes of boot time, but after between 5 to 10 minutes of using my PC, it will turn off and the state would be like the current state I mentioned above.
The steps that I took were:
  • - Tried removing RAM, but the problem would still happen
  • - Tried using generic PSU, but nothing wrong with my Corsair PSU
  • - Removed the CPU for about 5 times
  • - Change it with an old GPU (The old GPU will turn on, but my current GPU 1650 Super won’t)
  • - Used about 5 different old flash drives for the built-in BIOS Flash Function, but no luck
  • - And all the steps and instructions the internet could ever offer

Note: The GPU will turn on using the generic PSU without plugging it on the motherboard. Based on my findings, if the GPU is plugged onto the motherboard, the motherboard will instruct the GPU when it should turn on. So basically, it won’t spin because of the motherboard problem, specifically BIOS.

My final options are:
  • [1] To fix it by myself and use a programmer without removing the BIOS (The programmer can vary in prices like CH341A, ESP/EZPs, etc., but I’m afraid of the risks involved like bricking the entire motherboard because of varying voltages and my inexperience)
  • [2] To let an experienced technician to reprogram the BIOS using his expensive BIOS programmer (there’s a risk of bricking the entire motherboard)
  • [3] To let an experienced technician desolder the BIOS and reprogram it (The only risk is bricking the BIOS, but if so, I don’t know where to find a replacement).

Please let me know whether to choose option 2 or option 3 and if you have a fix for this problem.
Thank you so much for taking the time to read it.
 
Please connect only one stick of memory on DIMMA2 slot and clear CMOS by shorting the JBAT jumper for 5-10 seconds(with PSU powered off and power cord unplugged) to check whether the system could boot.
Has the 1650 Super graphics card worked on Windows 10?

Hi, I've already taken the steps you mentioned above. I've tried all the troubleshooting methods I could find, but none of them worked. I finally decided to have it de-soldered because I'm concerned that using a clip programmer might damage my motherboard. As for the graphics card, I used it with the system unit for three years, but I never encountered any problems.

I'll keep you updated if the unit is repaired
