The keyboard that i'm using doesn't work right lately. I've been using it for months already. Now, the big Enter key doesn't work, sometimes it works and sometimes it doesn't work at all. Also, I couldn't type "m" and "o". I tried to press "num lock" and other keys on the right side of the keyboard, sometimes I got those two letters work only once, then they dead again.
I thought it is the problem with the keyboard that i'm using. Thefore, I changed to brand new keyboard. This time, the "m" works, ENTER key works, but the "o", ".", and "(" don't work at all.
Also, a weird thing is that eventhough I didn't type the "p" key, but i kept popping up when I typed "a" and "u" key. This problem happens to both new and old keyboards.
I'm thinking about virus that causes my PC doesn't take the input keys correctly.
Any suggestion guys?
