Two things I would first check, \n1. Make sure the reset button is not stuck.\n2. Make sure your BIOS does not have the "Wake on LAN" feature turn on, especially if you have DSL, or Cable Internet.

Is the LED of the monitor glowing? Is it green or a different color? Is it steady or blinking?\nIf its a relatively new monitor, a message will be displayed if the signal cable is disconnected. If the LED is blinking, then the monitor is connected but not receiving signal from the system. If the LED is steady green, try increasing brightness and contrast. Do you see the monitor's onscreen menu?\nIf the monitor is older than 3 / 4 years you can expect a breakdown.

Could be that it was jarred and an internal component is not seated properly.  If you are comfortable with doing so, you can try reseating the memory, hard drive, wifi card, etc... to see if that fixes the problem.  If you are not comfortable doing so, take it to someone who is.

unplug it and plug it in again.  if this doesn't work, you may need a new power supply.  if you do need to purchase something, antec is good.

Reset CMOS. Better still, remove and replace the CMOS battery.  If that does not work, then you need to have the motherboard tested to see if the back panel connectors are working properly.\n\nEdited- PN   she said she already checked the keyboard on another pc, besides if the CMOS battery dies, it can do so quickly so you would not be able to tell if time was kept properly.  This is from years of experience with PC repair, so before you answer, read the question.

1.) Turn it off\n2.) unplug the power cord and ever thing on the back\n3.) Press and hold the power button for 20-25 sec then let it go.\n4.) plug ever thing back into your computer\n5.) Pressthe power button and see if it comes on.\n\nif it dose not work call someone who know what they are doing.

Sounds like it is the Ram. Take it out and re-seat it. If it stillbeeps take it out completely and see if the beeps are the same. If they are just go buy a new RAM stick. If that doesn't solve the problem it is time for a computer professional

mine would do that and it was the power cord , it wasn't in there tight enough . if there is a light that shows ou the plug is in see if it blinks every once in a while

u can't solve this problem unless u  repair the hardwares from ur pc. it might have an bios problem or ur hdd it's dieing... If u still got quaranty for it they should fix it.. if not go search some "hardware repairing shops" [could find a sinonime for that :P].

Reinstalling isn't always the answer. It may be that your touch-pad is faulty. You have to realize that touch-pads are extreemely sensitive not only to touch, but to temperature and moisture(humidity) too. you will need to order a new touch-pad, either from Compaq or another PC parts site, and just replace the old one. it's just as easy as replacing any other part. ps/2 parts are just plug and play.

I think it is problem in your BIOS settings. It is trying to detect a hardware that is not functioning. So try to correct the BIOS settings.

Your "back light" is gone - need to be replaced in service.\n\nPrice could be differnt from 0(still in warranty) to $200-300

I had a similar problem with my Powerbook G4.  The problem did not worry me for 3 years, until the logic board (motherboard) failed.\nThe stripe is most likely a sign of a failing logic board. Sorry.

The only way to really fix that is to exercise your warranty/consumer rights. If it's not acceptable most retailers will send you a replacement. If they have a dead-pixel policy that says one is ok, there's not much you can do from a technical perspective. The circuits are just too small and delicate to work with.

look at you device manager and if there is a ? question mark beside or inside C drive use the hardware wizard to locate it.if you have a systems check program use it and if all else reboot and see if the icon comes back on screen.if all that fails take in for repair.there are many pc geeks that can get you going in a few minutes if thats the problem but there could be others.prepare to pay some cash or check or use your plastic.
