So, I have a 1,5 years old Acer Aspire 5742G laptop.
Yesterday, few of my keys stopped working.
The keys are s,d,g,h,m,* and uparrow, writing this from on-screen keyboard.
I have tried cleaning up the keyboard, re-installing the drivers, even re-installing the whole windows. Nothing happened.
I play competitive cod4 and I losing money because of this problem almost every day.
ANY help is very much appreciated.
Thank you in advance!
