My keyboard stopped registering keys in the middle of typing. The function keys still seem to work, for instance when I press 's' it will open a search function in the app I'm in. But none of the text keys register for ordinary word typing. It's not just some keys, it's all the keys.
Things I've tried:
1. I have three keyboards, and tested and cleaned them all. The same phenomenon happens to each of them when I plug them in.
2. I've done a deep antivirus scan with Bitdefender, and a Malware Bytes scan. My system is clean.
3. My device driver says the keyboard is working properly
4. I've rebooted my computer several times. Then, sometimes on a random reboot, the keyboard will suddenly register the keys again. (I'm typing this on the 4th reboot this morning).
5. I've tried using different usb ports. Doesn't matter which usb port I plug the keyboards into, it's the same problem..
My system:
Windows 7 Home Premium
Motherboard: Asus P5Q-EM
Intel onboard video
4 GB RAM
When I've rebooted or switched keyboards, I'll test the keyboard by opening NotePad and start typing. Nothing happens, and no letters are being registered. But certain function keys seem to still work.
One thing I've noticed. When I open the start menu, I see an orange alert (!) on the shutdown button. When I hover my mouse over this, it says 'Installs updates and then shuts down your computer' So I'll shut down the computer thinking updates are being installed. But nothing gets installed. Then I start up the computer again and have the same keyboard problem. The alert on the shutdown button doesn't seem to correlate with the keyboard issue, since the alert is there whether the keyboard is registering the keys or not.
Is there some kind of Windows setting that may have been knocked off? Could there be a problem with a BIOS setting? Maybe a graphics issue?
I really can't figure this out.
Any advice would be appreciated.
