A common reason for this is that one or both of your RAM is bad. If you have more than one stick of RAM, you can try take one out while the machine is totally off and battery removed. After it is removed, reconnect the power and try to boot it up. If nothing changes, swap out the sticks. If it comes up with one stick in that means the other one is bad. You can run, albeit slower, on one stick as long as you need to, but it is recommended to maintain at least 1 GB of RAM at minimum.

Good Luck,

I have hp compaq nw8440 model. when turn on my lap top slowly white screen will start. just shaking or holding the screen picture will come clear. please tell me what is the problem

Sounds like it could be a loose connection between the screen and the motherboard. Not much you can do to fix it short of taking the computer apart completely. I would recommend taking in to a shop for repairs.

Compaq nw8440, XP, does NOT read dvds but reads vcd and data cd..

I don't know when the last time that you have installed XP, but it certainly would not hurt to reinstall the operating system again along with SP1, SP2, and SP3. "Microsoft Updates" site offers all of these updates for free provided that you have a legitamite copy of windows installed. The manufacturer's wesite offers free downloads to your model specifically, which could help. If you still have the original factory install and recovery disks, reinstalling the original drivers would almost guarantee no hardware problems. Drivers become contaminated and can lose the necessary information to make hardware work. It is also possible that your hardware is going bad. There are tests from your manufacturers website that will help you decide. Good Luck.

My compaq nw8440 does not power on anymore!

When you say "I bought a new power supply", do you mean you bought a new ac adapter?

Try this method and write back to me with the results:

1) Unplug the notebook and REMOVE the battery pack

2) Hold down the power button for 15 seconds

3) PLUG IN the ac adapter to the wall outlet (DO NOT PUT BACK IN THE BATTERY)

After you plugged in you pc, try powering on the unit again.

If it does not power on, please write me back.
