[SOLVED] Random keys on keyboard not working

[toaster389]

Random keys on keyboard not working - tried 4 wireless, 2 wired, all USB, all have different keys that won't work.


- All keyboards were new except the first

- Updated ALL associated drivers

- All other USB peripherals work

- Problem periodically stops for a day or two

- Replaced all PC components since it started except RAM, drives (1 HDD, 2 NVMe), and GPU

- PCIe USB card didn't help

- Did full antivirus scan via ESET NOD32

- Tried clean install of windows before and after replacement of parts

- Wiped all drives, even free space via CCleaner prior to clean installs and also reformatted all drives during windows installation

- Keyboard issues present EVEN AT BIOS LEVEL both on old and new motherboards, which can be seen by trying to set a bios level administrator password



I am using Windows 10 Home Edition (64 bit). My configuration is as follows:



Motherboard: MSI X470 Gaming Pro Carbon



CPU: Ryzen 3600



GPU: Red Devil Powercolor 8GB RX580



NVMe 1: 256GB, Samsung EVO 970 (This is my boot drive)

NVMe 2: 256GB, Samsung EVO 960

HDD: 2.75TB Seagate Pipeline



RAM: 32GB (2x16GB) G.Skill 2667MHz Ripjaws V DDR4



PSU: 750W Thermaltake Toughpower Modular Power Supply



Case: Thermaltake View 37



Sound Card: Sound Blaster Z



Does anyone have a solution I haven't already tried? All parts other than RAM, GPU, and drives are under 3 months old and I replaced them mainly in an effort to fix the keyboard problem. It didn't work. That was after trying all the things I previously mentioned. I'll try anything at this point.

Try a clean boot and see if it changes anything - make sure to read instructions and make sure NOT to disable any microsoft services or windows won't load right - https://support.microsoft.com/en-au/help/929135/how-to-perform-a-clean-boot-in-windows

if clean boot fixes it, it shows its likely a startup program. You should, over a number of startups. restart the programs you stopped to isolate the one that is to blame.
