Issue with BIOS update on NZXT N7 B550 Flashback problem detected in BIOS setup
It isn't mandatory, but given the problem, it's wiser to attempt this method since another part besides the motherboard could be faulty or causing a short circuit. This helps confirm the issue is with the MMO or PSU rather than elsewhere.
Despite having those parts, no power is being delivered. The motherboard depends entirely on 5VSB from the power source during this stage, meaning even if other elements failed, it wouldn't affect the outcome since they aren't functioning. I also question whether these parts are causing shorts or if a short exists that would be triggered by them.
I suggested removing possible error directions that don’t combine properly, meaning we won’t add many elements at once. This way, it will precisely target the solution and help you reach the root more quickly.
Removing the CPU, RAM, and graphics card together might resolve the issue, but determining which component was responsible remains tricky. If the problem doesn't repeat after replacing parts, it suggests a deeper issue. Be cautious about balancing risks during troubleshooting.
The goal is to update the bios. The problem is that flashback doesnt seem to work. this automagically puts the fault (if we ignore user error ) about 50% to the PSU 40% Mobo and 10% anything else. By removing anything else I now have to worry about the PSU and the mobo whcih are easy to troubleshoot (either they work at this stage aka at flashing the bios) or they dont. (that's attempt no1) So I will find out simply by testing an other PSU if bios flash fails (that's attempt no2) so in two steps I know what's wrong. If it happens to work then the issue is "anything else" so I go by checking one by one which component (or connection to the component e.g pins messed up in pcie slot or broken sata slot etc) is at fault by testing it out it would be most likely the RAM then the GPU then the CPU then the sata drive in that order. But it is highly unlikely (if the issue was that 10% aka anything else) for the PC to work properly because "anything else" can not just short the mobo just to the point where it cant make flashbacks if it was the reason (it being cpu ram or GPU or SSD) then it surely wouldnt work properly in general. or at all In other words I focus on what has 90% chance to be the failure and then if needed I test the 10% chance. Worse case scenario (when the problem is on that 10% chance issue so anything but the mobo and PSU) I will lose 2 steps but in most of the time (90%) I will save not checking out all the other steps needed for that 10% which are more than 2 steps quite a lot more. Ok you may now say hey how do you know that the percentages are 50% PSU 40% mobo and 10% anything else? I dont really but I have like 20+ years of experience with fixing hardware so I more or less know what is more likely to be at fault maybe in actuality (like in all systems I had to fix that had a similar problem) the distribution of fault wasnt exactly 50%PSU 40% mobo 10%anything else but it sure is more or less on that e.g 40% PSU 40% mobo 20% anything else or whatever. ** **EDIT obviously the above "ballparking" of the failure culprits refer to this or similar problems, obviously this can change depending on the nature of the issue e.g if the was to be "the PC boots but monitor turns black after posting" the distribution would drastically change.
I took apart the computer as suggested. While taking out the CPU cooler, I noticed the CPU wasn't in its socket—it was stuck on the cooler. It came off easily, suggesting it wasn’t firmly secured. The CPU itself appears intact, with no pins damaged or bent. Is this typical? The socket still holds the CPUs well. @Godlygamer23 I’ll check the other parts on my properly configured private machine.
Edit: Likely I applied too much thermal paste, which caused the CPU to stick. Cleaning it up was a bit chaotic. Updated March 8, 2023 by bakateo
Great update, the BIOS is now running smoothly! All set except the mainboard power cable—just plugged it in and installed the rest. CMOS was refreshed instantly. Thanks for your tips and support! I’ll install everything back into the case and test it soon.
