Faulty Keyboard? or driver issue or something else?

[chaththa4742]

Recently i got a laptop - ASUS X540LA core i3 broadwell cpu 4 gig ram and Intel HD nothing special about it actually. But very recently my keyboard has been acting weird and Typing things itself especially the letter M and sometimes the keyboard will stop working at all. No keys will function. i tought this was a software level issue and installed a fresh copy of WIn 10 and all the drivers. But the problem seems to be still exist. I noticed that when the keyboard will not work at all once i start the PC but it will begin to work after i just make the laptop sleep and wakeup again. But the occasional auto typing and auto scrolling down is occurring. Do i have to send the laptop for repairs? is this is a fault on the software level? Please help

Did you just restored the system and kept all previous files or deleted everything from the drive and reinstalled windows?
