Gateway Desktop Shuts Down when Ctrl Key Pressed

[jcook07]

I have a Gateway ZX6980 desktop, approx. 5 years old, with the original Acer wireless keyboard. I upgraded to Windows 10 last year without any problems. However, after the latest Creators Update in May, my computer began to enter shutdown mode occasionally and without any warning. After a lot of frustration (and going down various dead ends), I've figured out that the shutdown cycle is directly triggered by pressing one of the two Ctrl keys on the keyboard. I've done a clean install of Windows 10, which didn't help. I've also run Malwarebytes and don't pick up any malware. Finally, I checked the registry and don't see any reassignment of keys. Ideas?

Put new batteries into the Acer keyboard - just a matter of elimination.

Try another known working keyboard on your desktop.

Try the Acer wireless keyboard on another computer if at all possible.

See if the problem stays withe your desktop or follows the Acer wireless keyboard.

Belated thanks for your help (and from a different account, but it's the same guy). I ended up replacing the keyboard and it worked fine.
