So let me give a backstory and see if anyone can manage to figure out what’s going on with my PC. I started building a PC a couple months ago. Upgraded the processor, the case, the graphics card, the motherboard. All individually at different times. None of the components are the original, but I still consider it the same computer. That being said, I have torn apart and rebuilt this computer at least 6 different times, and never had a single issue. Ever. Even with the mobo swap. Fast forward to my current situation. One of the NVME ports on my mobo stopped working so I had to get it exchanged from Amazon. I get the new one. Brand new in box. I tear the computer down in a static free environment. For reasons that would take too long to explain, I assembled the components partially outside of the case to test the new mobo (installed the mobo in case, but everything else was outside). Works perfectly. Just like my old mobo but with 2 working M.2 ports. Then today. I assemble the rest of the components in the case just as they were yesterday. Start it up. The mouse and keyboard won’t connect to Bluetooth and some of the fans connected to the NZXT Smart Device V2 aren’t working (same fans that have been working since I upgraded to a NZXT case a month or more ago). But here is where it gets interesting. I don’t think my network and Bluetooth adapter card is broken. Bluetooth connects to my Vizio desktop soundbar and my phone perfectly fine. Just not my mouse or keyboard. Also isn’t the drivers for those devices because I didn’t change the drivers from when those devices were working just the day before. And I updated the drivers again just to make sure and that didn’t change anything. Now about the fans not working. So I have 3 fans connected to the Smart Device (for those of you not familiar with NZXT products, the Smart Device is a fan/RGB hub built into the case). All have worked in the past. Now one works, one doesn’t work, and the third gets power, but I can’t control it with NZXT’s CAM app. So it’s not the Smart Device, and it’s not the fans. Then what is it? If anyone has any ideas, let me know. My computer isn’t really usable until I can find out what the hell happened. I did everything today the same exact way I’ve always done things, but something went wrong apparently.
