so this morning my Toshiba laptop keyboard went crazy, I hit f and it types out the date and time, I hit l it types out 3/jklop and so on. I did system restore and reinstalled keyboard driver, didn't help. I turned it off for 20min. keyboard worked for about 10 then same thing happened. I started using the on-screen keyboard and when I hit j it goes into the login windows menu. I restarted the computer and now only the on screen works. should I reinstall windows or is this issue hardware, even thou the on-screen keyboard didn't work at one point.

sorry, but many keyboards, act up, maybe water is in it.this is hardware, dat means dat u can getchuu another one, how much was this keyboard, and the name of it, if u dont rememba the price, just give me the name, and what year u got it
