I've been having this problems for a couple of days now and don't know what to do. I keep getting the screen your device ran into some problems and needs to restart. stop code microcode revision mismatch. Tried to reseat my RAMs, unplug any external hardware. Tried to do a clean install with the usb but it won't boot it'll just take me back to the blue screen. I can only access the BIOs as of right now. Also looked it up with Microsoft doesn't really tell me anything. Bug Check 0x17E MICROCODE_REVISION_MISMATCH - Windows drivers | Microsoft Docs I guess it has to do with the microcode on the CPU.
