hp pavillion dv5000 windows 7 problems

So I just installed windows 7 recently on my sisters HP pavillion dv5000
There are a number of problems. First the keyboard is wack. After I type a few words it'll jump to a middle of a sentence before or 2 words before and start from there as I type. like I'll write hey how are you and it goes between h and ow and starts the cursor all the way over there or it'll be gone and start no where. and it'll go to the post button or something.
Another issue but not as big is the fact that there is a mute button if you are familiar with the HP pavillion DV5000 and when you press it the light goes on, if you turn on the mute. This always happens. It happened when I still use windows XP, now that I changed it to windows 7 however it no longer works. If I press mute or even if I don't the button is not turned on.
Any one can help? ESPECIALLY with the wacky keyboard situation. I can't type anything without it going back midway and start to type out of the wrong section of it. Thanks

Sound Issue: whenever I hibernate then restore windows the sound is gone! I cannot get it back unless I restart my PC.

Reghakr is right install the newest drivers from HP and that should clear up the issues.

you can install the Vista drivers for the media keys just remember to right click them and then run them in compatiblity mode with "Vista SP1" and run as admin.

You sure your hand is not touching the trackpad? This used to happen to me while dealing with certain laptops. I would think, wtf - wack keyboard. Even my dad came to me with a similar problem.

Try plugging in a mouse and disabling the trackpad. See if that helps.
