SOURCE: problem with compaq presario r4000 constant beeping no keyboard
Need to know the number of beeps. They're called beep codes. This page lists some of the Compaq beep codes and what they mean.

Use a computer with Internet access to download the drivers and then copy them to an USB memory stick. You then insert the USB memory stick inti your Compaq and install the drivers.
You can download the device drivers from the Compaq/HP WEBsupport/download page. Make sure you select your model laptop and the Windowsdrivers you require and install them. Click on this link to download thedrivers: -

Take it back to the place of purchase since it is under warranty, otherwise you will damage the processor which the cooling fan protects.

RESTORE YOUR COMPUTER! This just happened to me and i looked up and tried EVERYTHING! Since my wifi button had only stopped working 2 days ago, I restored my computer to 4 days prior because I was told that sometimes without you even knowing you allow stuff to get on your computer whenever you get online which could cause your computer to turn functions off automatically. My wifi button actually stopped working after I went into a mcdonalds with my computer an used their wifi so I think me allowing their wifi onto my computer did something to it because when I took it home the button was just red altogether and it was SOOO frustrating. But as soom as I restored it, my computer came back on and a little window popped up saying "Your wifi is currently off, toggle your wifi key to turn it on/off". I was so happy! The simpliest thing that no one would ever think of.

I have experienced the similar problem as yours. I forgot my HP Compaq Win 7 laptop password, finally got out of problem by DIY a password reset disk with Windows Password Recovery Tool 3.0. Your blank bootable USB Flash Drive will help you much now!
