Something is up with my PC

[SinHarvest24]

Here is what's wrong, this morning when i used the pc everything was working as normal but when i went out, leaving the pc on (for like 2hrs) and came back my pc was acting all weird. When i say weird i mean it's inputting keyboard commands and right clicking? i don't know if there's a keyboard command for a right click but it does all this without anyone's doing. It's also beeping as though i'm pressing more keys than i should. I think it's a keyboard problem, any idea's?

Restart your PC?

Check if any buttons on your keyboard got pressed down. My Ctrl button got stuck down more than a few times. XD

It might sound stupid, but turn your keyboard upside down and give it a few whacks over your knee or something. It could be crumbs or something stuck in a key, or a key (like ctrl, alt, shift, or f1-f12) stuck down. Also make sure sticky-keys is off (mash shift repeatedly) and run Spybot to be sure its not something/someone external doing it

I restarted already, checked sticky keys and wacked my key board as you suggested but the problem persists. I am quite sure that's it's a key board problem now, a short maybe? cause when i moved around the keyboard it seems to "act up" more.
