G 580 intel i5

product: 2189

no.series: CB20561632 

BIOS: SECN92ww(v8.04)

windows 8.1

Recently I've bought new Lenovo G 580 but I am having a problem:

Every time when I type in any number or letter(mostly no.1) into any window( password,bank account,log in,google translate, etc.), inexplicably starts endless series of dots which I must stop and cancel with cancel key every time it happens.

This creates me huge problems in daily work.(even now while I write this)

e.g.

Does it do the same when you boot into safe mode (you can change to safe mode in msconfig wiki for how is here)

Have you tried reinstalling the keyboard driver?

I would also run a system file check to check the OS

Please run a system file check (SFC)
