2 beeps usually means a memory error, however, you should get an error message. Try removing and re-inserting the ram modules one at a time
I assume you have tried to see if the ac adaptor is putting out the correct voltage?

Delete any/all antivirus softwares on the computer. Restart computer and go here to download Panda free trial. Works great and after the trial I would suggest buying this software because it will save you from tech fees.

This advice relates to the Compaq Presario 3000 Notebook series but may also apply to other notebook computers as well.

The heat sink and fan assembly is probably clogged with dust and airborne particles. The clogged cooling parts can lead to heat problems with the CPU. When the system (CPU) gets to hot, the fan has to kick into high gear to try to cool things down. Once you remove dust and debre from the heat sink fins and fan, you will immediately experience better cooling and less fan usage. Your system may also be set for dynamic switching of CPU speed. If you CPU gets too hot, the system will reduce clock speed and ramp up fan and everything will slow way down. Use a good system monitoring software such as Notebook Hardware Control to monitor your CPU temperature, HDD temp and so forth. When the system starts getting too hot, first look at clogged heat sink fins as possible culprit. If you're good at electronics you may be able to service the unit yourself. Get a copy of the system's Maintenance and Service Manual or have a professional do the job for you as you will have to partially disassemble the computer to clean out the heat sink. Depending on the system, the job can take as little as 15-20 minutes once you become proficient at it.

If you're sure about your issue, you can get one hard drive on the internet and replace it.

Most CPU fans are controlled by CPU temperatures and even when loafing, they get hot. When you DON'T hear them cycling, it is then time to worry.

my sugestion is to place your ear near notebook and turn on if you hear the hard drive then majure problem but if you hear hdd is quite then it sounds like the fans thet cool the notbook down get this in for repair as soon as you can hope you get it sorted soon good luck
