I found myself at the end of a goose chase that ended in needing to reset the OS through the Windows 10 reset function. No problems since as the original issue concerns, although I'm now unable to control my B450 Asus Elite's RGB through RGB Fusion 2.0 in the boot menu- perhaps on a related note I'm unable to install the Asus Aura Sync to control my RAM's RGB (some none-sense about incorrect parameters that no one on Google has ever seemed to experience). My slightly less than mediocre investigating skills point to drivers that have been removed since the reset (I couldn't even hazard a guess which ones), or an update to the BIOS being needed. There is a third possibility that the mobo isn't detecting or is missing a bus controller, again, no idea how to approach. So the main obstacles in my way of doing 2/3 of these options is that I don't know what's missing. The big one for me is updating/flashing the BIOS. I know for a lot of you that's a simpler thing to do these days, but for me it terrifies me to even think of trying it considering there's a possibility of my unlucky and inexperienced self bricking my newishly built PC, particularly after the heartache of having to reset the bugger's OS three times in reasonable succession. To me, this is a pretty big deal just to get some poorly made software to work. At the moment I'm on the cusp of paying a trusted local repair place to have a nose for me, but I'd rather not do that so early into my rigs life- particularly after being built air-tight by Overclockers and me messing it up over an accidentally deleted important system file (thanks OneDrive). If there's a simple fix for this that I'm just blind to and someone here brings it to light, I'd build a monument to your honour atop the greatest hill in Wales. Cheers!
