[Josf]

Hello,
I'm using Sony Vaio VPCEA16FG series laptop and I'm facing weird problem. Some times my laptop keyboard auto types randomly and some times some of keys like backspace, P, 7, Space bar they don't function and I can hear fan running at high speed and if I try doing power button reboot it get struck at windows memory diagonistic. I have recently replaced the laptop keyboard cause of same issue like 20days and with the new keyboard problem starts again. Please can any help me how to resolve this issue and what exactly causing the problem to malfunction like this. Is it cause of RAM, or poor battery or any other ?

It could be related to a virus or Windows has somehow became unstable / partially corrupted.

Do a virus scan, and also try using Malwarebytes so see if there is any malware. If a virus is not the problem, then you should re-install Windows. Backup any important files on the C: Drive because everything on the C: drive will be deleted.

Malwarebytes, scroll all the way down for the free version.

If re-installing Windows does not fix the problem, then you have a hardware issue which means you need to bring the laptop to a repair shop to see if the problem can be diagnosed.
