If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp. Please click on this link and follow myinstructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

It sounds like you do have an overheating problem. When the laptop is running, peek inside the vent on the side or bottom of the laptop and determine if the fan is running. If it is running slow or completely stoped, that is your issue and it should be replaced by a local repair shop.

If the fan seems to be running fine, you may be able to deal with the problem and extend the life of the laptop a little by buying a laptop "cooling pad" which will have cooling fans of its own.

You can download the drivers from the Compaq/HP WEB support/download page. Make sure you select your model laptop and the XP or Vista Windows version of the drivers you require and install them. Click on this link to download the drivers: -

If the CPU fan speed is too slow or not working at all, the computer will shut itself off automatically to prevent damage to CPU from overheating. You may end up having to throw more money at the problem and get a new fan. I went to Compaq's web site, looked up your particualr computer, found out what type of fan you needed, and I did some research. I recommend getting the fan in the following link. It's very cheap, and has good reviews. The other fans on the site all have bad reviews. Hope this helps.
