    Refer to your motherboard manual, since the motherboard is the beeping device. These beeps are like Morse code, and each "beep code" is explained in the manual. Common beep codes include not having a monitor or keyboard properly connected; not having a CPU fan connected, or not attaching internal power cables to the video card. This black-screen-and-beeping issue is most common with newly-assembled computers.

    Check external cables to make sure they're properly connected. The most important external connections to check are the monitor's signal cable and the keyboard. If your monitor cable looks damaged or kinked, try replacing it with a spare. If your keyboard's cable looks frayed, try a spare keyboard.

    Also, a PS/2 keyboard plug (round, with holes in it, about the diameter of a finger) is often color-coded purple. If you have plugged it into the green port in the back of the computer (for PS/2 mice) switch it to the other one. If there is no color coding, the proper port should have a small, embossed icon of a keyboard on the back of the computer. If it does not, refer to your motherboard manual for the correct port. If all else fails, try a spare keyboard, preferably USB (Universal Serial Bus), which can be plugged into any USB port on the back of the computer.

      Check for additional motherboard power connections. Yours may require multiple cables attached from the power supply. There is the standard wide plug, which you know is connected properly because your motherboard is beeping. However, there may also be an additional, four-pin cable that connects elsewhere on the motherboard. Check the board's manual to make sure it has all the power connections it needs.

      Check your internal cables. Make sure that the CPU fan is plugged into the motherboard header nearby. Without that, the CPU fan will not spin, and the motherboard may detect this lack of connection and produce a beep code. Your video card also may have one or two internal power plugs that need to be attached to the power supply's cables. These cables have unique ends on them, similar in shape to a USB plug. Refer to the case or video card documentation if need be. If those cables are not attached, your motherboard may refuse to boot the system.

      Your video card may be faulty. If this is a new card, it may have arrived to you broken, in which case you will probably need to request an RMA (Return to Manufacturer Authorization) to receive a replacement. If this card was previously working for you in this system, you can contact its manufacturer yourself to receive a replacement, if the device is still under

      Why does the screen shut down after 1 sec while sound continues

      It sounds like bad luck to me. You cannot change any settings on a TV by connecting a computer to it. In theory you can damage any monitor by setting the screen resolution of the computer higher than the monitors maximum res. The Sharp 26" has a resolution of 1366 x 768 (1080i) so (again in theory and I have never seen it happen) if you set the output to 1920 x 1024 (HD - 1080p) it can kill the screen. Perhaps this is what has happened. You will need to take it to a Sharp service centre.

      Adding mp3's for the alarm clock.....

      If you are like me, you are not impressed with the alarms that came with the hero (sprint). They were too short, and I slept through all three that I had set. However, you can use any of your mp3's as alarms. This is not a difficult process, but it will involve using your phone as an external storage device, and creating a directory on your SD card.

      Connect your phone to your computer and through the notifications screen, mount the SD card so you can see it on your computer. Navigate to the /media/audio directory. Inside the /audio directory, create a directory titled 'alarms'. Copy any mp3's you want as alarms into this newly created directory.

      Remember to turn off usb storage from the notifications screen.

      Go to the clock function, set an alarm, and you should see those mp3's available on the alarm sound list.

      Good luck waking up!

      Precision T7400 power supply sounding an alarm

      Did you open the case on your computer? It may have an open case alarm which is a small switch typically located near the edge of the cover you removed. Make sure the case cover is completely installed, then see if the alarm goes off.

      So the big one with the screen on me took a **** awhile back. so i was only using the black one, but now the dog ate it? If i use the key the alarm goes off. HOW DO I TAKE THIS OUT MY CAR?

      Hello my name is Israel and I will help you. You can still use the alarm but you will have to do a couple of steps. Enter the vehicle. The alarm will sound. Insert key and turn to the 'run" position. Push or set the override button and alarm will turn off. The remote should be easy enought to replace. If you want to replace it, let me know and I will try my best to get a remote for you. Good Luck.

      Green light, black screens, no sound, needs new battery???

      The alarm is just a coincidence i suspect, green light comes on and stays on probably not the battery at fault. It would be red.
      If the green light goes out and screens just flash one of your screens are at fault or a loose ribbon connection.

      Alarm goes off when it starts up

      The alarm is a BIOS alarm. It is warning you of either a cooling fan failure or the processor getting too hot. Either way, you need to fix the problem, not just ignore it!

      I would check that all the fans are running correctly and would also recommend that you give the insides of your computer case a clean out - you'll be amazed at how much dust can build up in there! This may well cure the problem.

      If it is a processor temperature alarm, rather than turning it off, you may want to adjust it so it doesn't sound until a higher temp. is reached. You can adjust this from the BIOS screen, but I would check the maximum temp. that your processor is designed to run at before doing so.

      To get to the BIOS screen to turn it off, press the delete key (repeatedly) while the machine is booting.

      I can't tell you exactly when to find it in the BIOS, as this can vary from one computer to the next. Just navigate you way around until you find the relevant section.

      **** WARNING ****

      Changing settings in the BIOS can affect the computers performance, prevent it from starting, or even cause permanent damage to hardware. Unless you know exactly what you're doing, I wouldn't recommend changing things!

      Hope this helps,
