Beeps During a normal Windows session, my computer will make a scanning beep sound. It is really fast but not too loud. It is very random though. There are no errors followed by the beep or signs of change. WHAT IS THIS BEEP. (i know the normal hard drive read/write sound and this is different)

Go to a auto parts store, they can scan your computer for free

Hello, I personally have had this same problem. The loud beeps that you are hearing are notifying you that your RAM (Random Access Memory) is corrupt. The way to fix this is to remove the back plate of your computer and replace the RAM chips.

Here is how to do that.
Just select your model of computer, and then find the guide for "RAM Replacement"

some laptops and desk tops beep on start up.but some beep when it has ram problems.

those windows sounds are adjustable

start
control panel
sounds icon

look for windows sound settings find the one that says beep and disable it

Sounds like a bad/overheating hard drive or possibly the ram is defective.The hard drive may have developed bad sectors and/or delays.Overheating really seems to be a problem on the new smaller and thinner laptops.The hard drives are confined to such small area causing them to overheat and develop bad sectors and worn spindles plus disc surface damage.Try removing the hard drive and see if the beeps continue and also see if you can clean the CPU of dust and lent with compressed air with it off and unplugged.Get back to me after you try that

Looks indeed as if the TAB key was stuck or malfunctioning. The most common cause for such behavior is a liquid spilled on the keyboard, a bit of which got between the layers of the keyboard membrane films and causes intermittent semi-short between conductive areas.
A trace of liquid caught between plastic films is hard to get rid of, as it practically sealed and doesn't evaporate.
If it doesn't go away, you may need to replace the keyboard, which is not very expensive fortunately,

How many beeps do you get, this is very important to your solution.

This is normally a indicator that key is stuck, or multiple key strikes on the keyboard. It could also be an intermittent problem. Either way, this isn't something to get overly concerned with, unless it gets worse.

what is the beep combination? how many short and how many fast beeps?

The touch pad may be defective. There is a membrane behind the buttons that will cause problems like that. The only cure is to replace the touch assy.
