Question Keys being pressed randomly... Help!

[Thegr8ashish]

Hello,
Few days back randomly my mouse started sliding on its own, I tried unplugging and reinstalling the driver didn't worked but after few days it got fixed on it's own but now my keys on my keyboard started pressing on its own randomly, and it's making me impossible to navigate or do anything, almost a whole row of keys shown are pressed, I can see this because of a rgb mode.
There's is no usb problem I think because sometimes I work it's fine, but when I leave it idle for some minutes it starts acting up again.
I have a Logitech g402 mouse and ant esports mk 1000.

1.I have tried reinstalling drivers.
2.Unplugging and reconnecting the keyboard.
3.troubleshooting

Have the peripherals ever been exposed to liquid? Tried using different USB ports?
edit: This was targeted primarily towards the keyboard

As far as the mouse goes, simply grabbing a Q-tip and a bit of rubbing alcohol, then cleaning the sensor on the bottom on the mouse should fix that.

Yes, I tried all the ports available in my desktop.

I also tried using it on another laptop, it worked fine at first but after sometime it resumed to the problem again.

I don't think it have been exposed to liquid but I could be wrong.

Also the keys are pressed at all times, it's not about the keycaps too because I even removed them all.
