Keyboard problem, not able to type at all.

A few nights ago keyboard was working fine, the following morning I turned my PC on and I cannot type with my keyboard.

 

Specs:
- Win10 Pro x64 - Version: 1803
- Keyboard = Razer BlackWidow Chroma
- Driver software = Razer Synapse 2.0

Things i've noticed:
- BlackWidow Chroma AND Mamba not showing in Synapse.
- Device manager showing the "!" next to some keyboard and mouse devices.
- Might of been a windows update.
- Keyboard LEDs works
- Keyboard works in BIOS
- Keyboard works on other PCs

- Mouse still working


Things i've done:
- Restart PC (almost every time after i do one of the things below)
- Changed USB ports
- Update Synapse

- Tried older versions of Razer Synapse 2
- Tired Razer Synapse 3

- Run Win10 updates
- Tried updating drivers in device manager.
- Uninstalled Synapse + delete devices in device manager + delete all razer folders in c:\programfiles x86 and c:\programdata + restart PC + reinstall Synapse
- Uninstall Windows 10 updates that installed in the last 24 hours.
- Hold down esc + caps lk + m5 and plug in keyboard.

- Boot windows into safe mode.
- Tired other keyboards. (no keyboard i plug into PC works)

- regedit - deleted UpperFilters in the keyboard class (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\some numbers and letters :))


Any help would be great. Let me know if i'm missing any information.
Also ceebs reinstalling windows so don't suggest straight away plz xoxo.

Try reinstalling the USB drivers for your motherboard.

Thanks for getting back to me.

 

I updated the USB drivers and a few other drivers while I was there, including chipset and even bios.

No luck, the keyboards I plug in still don't let me type and i tried multiple ports. Even pressing caps lock and num lock doesn't turn the little led on. (rgb leds on keys still on)

I also double checked keyboards on another win10 pc, they still work fine on that.

 

One thing did change though, I have no missing drivers in Device Manager now (no "!" on any devices).

 

Little more info:

- When I plug in and out the USB for the keyboards Device Manager refreshes itself each time.

- When I Teamviewer into the PC I can type fine from remote PC.

 

 

 

Any other ideas would be greatly appreciated.

Try going into your motherboard bios, finding a setting that lets you switch between "partial initialization" and "full initialization" for the USBs under the Boot menu if it's the same as my bios, and switch it to "full initialization".

This solved a similar issue I had with USB devices acting wonky after startup here and there.

 

Just be careful not to mess with other USB settings too much without a backup like a USB card or a PS2 mouse because some bios USB settings can cause your mouse and keyboard to stop working in the bios. I've even seen it where clearing the CMOS wouldn't fix it for some reason I can't explain so have a backup if you mess with anything other than what I mentioned.
