My 1 year old computer has a black screen but u can hear the computer running help....


Are you getting any beeps while your computer starts up or when it has already started? If yes, then refer to the following HP Support page to get details about different types of beeps and the respective issue they indicate:
http://h10010.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c02222922#N315
If you are not getting any beeps, you can start troubleshooting the issue by first checking the connectivity and performance of your monitor. To do this, refer to the steps below:
1)Make sure that your monitor has power and the power light on it turns On when power is supplied to the monitor. If the light stays Off, turn Off the power supply- unplug and plug the power cord- reseat the power adaptor connection on your monitor's end- turn On the power supply. If the monitor's light glows, see if the computer still shows the blank screen. If yes, follow the steps ahead.
2)If your monitor is of flat panel LCD type, unplug its power cord and wait for around 30 seconds so that the electronics in your monitor are reset. Now reconnect the cord and turn On the monitor.
3)If you are still facing the blank screen issue, disconnect all the connected devices to your computer except mouse, keyboard, and monitor. Also remove memory cards from card reader slots (if any) and thumb drives connected to your computer (if any).
4)If the above steps do not resolve your issue, you can try (if possible) to connect your monitor to another video cable (if it is detachable) for testing purpose.
If the issue still persists, you can refer to the HP Support links below to troubleshoot your issue:

Hp desktop keeps crashing


Agreed not a lot of info, but you may not know what is going on, so s'okay.

There are three main reasons for desktop computer failure;

1) The computer is dirty inside.
Over 80 percent of the personal computers in my shop, suffer from this 'ailment'.

What happens?
The Processor overheats, and turns off. (BIOS turns it off)
This is because there is a fail safe feature built-in. Keeps the Processor from burning up.

The hardware components inside your desktop computer, (i.e., Processor, motherboard chipset, Ram Memory, graphics chipset, {Integrated graphics}, or graphics card, etc.), are cooled by AIR.

When dust, dirt, hair, food crumbs, spider webs,you name it; clog the cooling system for the computer, the temperature inside goes up tremendously. Especially for the Processor.

[ I just cleaned out an old Dell desktop computer, for a store. Worst one I have seen in 14 years. Had 3/4 of an Inch of hair, dust, dirt, and junk, on the bottom of the computer case. The computer case fans were so clogged with 'dust bunnies', I could NOT see them. The Processor fan was one dust ball, and the Heatsink underneath looked like a solid block. Couldn't see the fins.

Q-tips, a soft small brush, and THREE cans of compressed air for computers, later, the computer is working fine again ]

Start with this, then if it does not sure the problem, state back in a Comment.

ONE:
Unplug the computer from power.

TWO: FOLLOW Anti-Static Precautions.
(Don't know? State in a Comment)

THREE: Post the computer manufacturer NAME, and Model Number. I'll tell you how to open the computer case.

(It's on the back of the computer case, (Tower), next to the Windows product key, OR up on the side of the computer tower.
For an HP, or Compaq computer it is the Product Number.
It is in the white Service Tag, and is P/N )

3 year old Dell desktop computer does not power down, fan keeps running and green light blinking. I am going to Start, turn off computer, turn off. I have unplugged the computer and started it up again,...


Usually when a computer won't shutdown in WinXP it is trying to close many files. It sounds as if you have something hanging up and until you find the specific driver this will continue.
I would first check your registry with some type of utility like Norton Disk Doctor which checks and removes unused and garbage from your registry. This would be at least a first start to find out what is happening.

HP Media Center Desktop w/XP


Why would you want to connect to Windows? Yecch. Go to OSNews.com and check around for an interesting OS and filesystem combination.

Still, I'd chalk it up to your having plugged another bootable volume into the machine (e.g. a CD ROM) or otherwise changing the setup from what you brought to GeekSquad. Honestly, you've described the problem circumstances quite poorly. Does it not beep before booting -any- OS?

HP desktop monitor problem


hi try this ,,,
  1. Ensure the video cable is connected (and connected to the correct video port).
  2. Turn off the monitor using the monitor's power button and then restart the monitor.
  3. Cycle the power on the monitor as follows:
  4. Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
  5. Unplug the power cord.
  6. Wait 5 seconds.
  7. Plug in the power cord.
  8. Press the power button on the monitor to turn on the monitor. One of two things happens:
    1. The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
    2. The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution
    3. Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
      • If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
      • If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
      hope it will work for u .. little_angel
