Desktop Power Light Pulses

Hello and good morning. My house, specifically my telephone and cable modem lines, took a direct lightening hit and now when I turn on my PC the power light just pulses. I had the power supply tested at Tiger Direct and it tested good. The PC was surge protected so I think the damage likely came through the cable modem. PC is a Gateway GT5222E with a MS-7248 Motherboard. I'm leaning towards replacing the motherboard but would appreciate any other, less expensive, suggestions. I do not currently have the necessary spares to move CPU etc around and run tests.

Try removing all PCI/AGP and RAM cards from the motherboard and disconnecting all drives via their power and ribbon cables too and see if you at least get the boot process to start. if not, that confirms your motherboard is bad.


If it does start but gives errors for the missing components, start putting them back in or connecting them back up one at a time until the problem returns and then you have your failed part.

Where is the wireless switch on the dell vostro 200


Unlike notebook computers, most desktops don't come with wireless networking built in. I can't find any mention on Dell's site that the Vostro 200 has wireless capability, so this computer doesn't have a wireless switch. To use your desktop computer on a wireless network, you'll need to install a wireless adapter. USB adapters are very easy to use since you just have to plug them in. They're not expensive and you can easily find them at retail stores and online.

My dimension 3100 is not detecting a modem


Sir,
Respectfully please first check if there is a modem in the desktop PC since the dimension 3100 is not pre-equipped with a modem. you have to attach an internal modem manually on one or more PCI slots on the mother board.
the process is given here....

1
  • Turn off the computer. Unplug the power cord from the electrical outlet. Disconnect the power cord, attached peripheral devices and any other cables.

  • 2 Locate the cover release latch on top of the computer, near the back. Place the computer on its side, with the removable cover facing upwards. Slide the cover release latch back and lift the removable cover off of the computer. Set the removable cover aside.

  • Locate the PCI and PCI Express slots near the bottom of the system board. Select a slot that corresponds with your internal modem card. Open the card retention door on the back of the computer and remove the filler bracket for the card slot you will be using.

  • 4 Place the internal modem card into the appropriate card slot and press it firmly into place. Close the card retention door. Replace the removable cover and return the computer to an upright position.
  • 5 Connect one end of the telephone cord into the LINE port on your internal modem card; plug the remaining end into a telephone jack. If desired, connect a telephone to the internal modem card via the PHONE port.
  • 6 Reconnect the power cord and all previously disconnected cables. Plug the power cord into an available electrical outlet. Turn on the computer. If any installation software came packaged with the internal modem card, run the program and follow the onscreen directions. Your internal modem is now ready for use.

    I'm having trouble connecting my emachine to a cable modem.


    Turn off the computer before you begin making connections. Make sure the cable modem is up and running with your service before you attempt to make the computer connection.

  • 2 Connect the coaxial cable from the wall outlet into the back of the cable modem where it is marked "Cable" and has the male coaxial connection. Use an extension coaxial cable if necessary to reach the modem.
  • 3 Connect the CAT 5 networking cable from the cable modem where it is marked "PC" (or something similar) and connect the other end into the back of your computer where the networking card is. These connections are RJ-45 connections that look like oversized telephone jacks. If you also have telephone service through your cable provider, you will want to connect the telephone line into the port on the back of the cable modem marked "Telephone."
  • 4 Connect the power cord into the back of the cable modem and plug it into a power strip with power surge protection. The modem should power on by itself once it is plugged in. It will cycle through a power on self test and then make the connection to your cable Internet provider. Once the lights indicating power and cable are green, you are ready for Step 5. It could take several minutes for the modem to connect to your service provider.
  • 5 Turn on the computer and test out your Internet connection. Should your computer still have a problem connecting to the web you may need to reset your cable modem. You will find a small recessed button the size of the head of a ballpoint pen either on the back or front of the modem. This button will be marked "Reset." Pushing it once will allow the modem to reboot and reset all its connections. Turn off the computer before resetting the modem to allow the computer to flush all the networking connections out of its memory as well.


  • If the power goes out and your connection is not restored when it comes back on, always reboot the devices in this order: cable modem first, computer second. Keep the cable modem where it can get proper ventilation. Call your cable Internet provider if you get frequent interruptions to your cable Internet service and rebooting the modem does not solve the problem.

    How can i connect my desktop computer to the internet plz i need someone to help


    Currently, the most common way to connect a desktop system to the internet, is by using the network jack to connect to a broadband cable modem or DSL modem. To do either you must have the service from either you cable provider or phone company (For DSL) and have the modem device for the service. Fees run $20 to $50 a month depending on speed you subscribe.
    You connect the device to the system using a CAT5 network cable to a RJ45 (8 wire telephone type jack). Some Cable/DSL modems also have USB connection capability for the few systems these days that do not have a built in RJ45 connector To use them, you install the associated software, then connect the USB cable when prompted.
    If you don't have Cable/DSL then dial up telephone modem is the next option, this requires a telephone modem that has an RJ11c telephone cord jack connection, most current computers only have a telephone modem as an option, but they can still be bought for around $20 and you will require a dial up internet service (Few remain, one is Netzero in the USA)

    IE has been only working off and on all day. What


    Probably internet connection issues.

    (***Do this after talking with ISP***) Power down your modem, router, and computer. Check to make sure the internet cable is secure. If you have a replacement cable try it. Power up your modem 1st (wait 1 min.), power up you router, then your computer.

    ***1st check with your ISP*** (Internet provider... cable or dsl) to ask them to check the integrity of their line to your modem (they can do this easily). They will give you a rating of Good, Poor, No Connection. They will help you if it is Poor or No Connection (their side problem). If it is good they may have you power down the modem (and router-if you have one) and connect your computer directly to the modem (and reboot) to help troubleshoot.

    HAVE TATA INDICOM LG250 MODEM CONNECTED TO MY DESKTOP PC I WOULD LIKE TO CONNECT IT TO MY HP PRESARIO C700 LAPTOP. I HAVE LAN & TELEPHONE CABLE TOO. CAN I CONNECT IT AND ACCESS THE INTERNET?


    as long as you have the ports for it yes, are you trying wireless, or a wired connection? depending on how old or new your laptop is you may be able to connect the telephone line right into your laptop, although that would be dial up and very slow so i would recommend using a cat5 cable aka normal internet cable

    Was able to get connected to the internet twice to day when i came back in to get on the computer it couldnt connect to the internet said no dial tone. this is a new dell computer with an external modem...


    Generally this is an indication of a modem failure. If there have been any storms in your area, then the modem may have been zapped. The dial tone curcuit is normally the first casualty when a modem gets hit with more power than normal.

    Provided that your telephone is functional on that line (Unplug modem, and connect a handset if this is a modem only line and see if the handset gets a dial tone, this is a good check to make sure the line is functional)
