Guide to upgrading a Motherboard (12/01/2000)


    UpGrading a Motherboard is not difficult

    Several different upgrades can boost your PC's performance, but for a real jump for your old PC, nothing beats a full motherboard upgrade. A new motherboard, coupled with a high-speed processor and a generous amount of RAM, can dramatically improve system performance. It's not a job for a beginner, but if you're comfortable doing major poking around in your PC (or have a computer-sa...This TV Show is available upon demand...This means if you want the download link for this show, you should  reply here and we will reply  for you the download link ASAP...So please if you want to download this please don't hesitate reply here and we will be more than happy to post it for you....y friend to help), the operation isn't too difficult.

    Most motherboards today retail for $60 to $250. Midspeed processors, meanwhile, cost from about $100 (for a Celeron-500) to $200 (for a Pentium III-600 or Athlon-700). Don't skimp on RAM, either. Go for 128MB (about $80). For a total investment of between $240 and $700, you'll have a powerhouse PC. If your budget is smaller, consider 64MB of RAM (about $40) and a lower-end CPU like AMD's K6-2-500 (about $60), dropping the bottom line to about $160.

    Most computers made in the past three years have cases that require a motherboard with an ATX form factor. If you're replacing an ATX motherboard, you can choose from a wide variety of boards, differing mainly in the processor types and speeds they support. Your best bet is to choose the processor you want and then purchase a motherboard that supports it.

    If your PC is older, its case probably requires a board with an AT form factor. Check your system manual to be sure, but if your serial and parallel ports aren't built into the side of the board, you probably have an AT motherboard. If so, consider buying a bare-bones ATX system--essentially a motherboard (usually with CPU and RAM) installed in a case with a power supply--and then transfer the drives and cards from your old system to it. Watch out, however, if you have lots of ISA add-in boards. Most new motherboards have few (or no) ISA slots...  or simply invest between $30 to $60 for a new ATX case as part of your upgrade.

    The occasion of replacing your motherboard is also a good time to upgrade other components in your system, such as the hard drive or the graphics card. Before you start your motherboard transplant, of course, run a full system backup.

    1. Remove the Cards and Cables
    Turn off your PC; unplug it from the wall; and disconnect the mouse, keyboard, monitor, printer, and any other external cables (such as USB). Remove the PC's cover, and carefully look at what you need to remove or disconnect to reach the motherboard. In some cases, you'll have to remove a hard drive or other hardware to get to the motherboard.

    Before you begin working under your PC's hood, put on an antistatic wrist strap (available from a local electronics supply store such as Radio Shack) and clip it to a grounded metal object. Cost here is between $4 and $10.

    Remove the screws holding the add-in cards, carefully remove the cards, and lay them on a clean, flat surface, preferably in the order in which you removed them.

    Label each cable with masking tape and write down each connection as you remove it. Unplug the power connector, the floppy disk cable, and the EIDE connectors. Make sure to note which cable is connected to the primary and which to the secondary EIDE connector (sometimes they're marked Channel A and B, or 1 and 2).

    Finally, unplug the small connectors attached to the front-panel switches and LEDs.

    2. Remove the Old Motherboard
    Most motherboards are attached to the case with a handful of screws--usually about five, but the number can vary. Find them, carefully remove them, and set them aside in a handy container, such as a coffee cup or that ashtray you don't use any more.

    Remove the old motherboard by sliding it slightly toward the front of the case (so the connectors at the rear are clear of the case) and then pivoting it upward.

    3. Install Ram and Processor
    Before you mount the motherboard in the case, insert your new RAM module (or modules) into the RAM socket (A), beginning with the socket marked "Bank 0." DIMM modules fit only one way. Slide them firmly into their sockets. Brackets on each side will snap into place automatically when the module is correctly seated.

    Most of today's CPUs fit into sockets. To install a socketed processor, lift the lever on the socket and carefully insert the CPU (B), making sure that Pin 1 on the CPU matches Pin 1 on the socket. Hold the processor firmly in place and lock the lever down. If you're installing an older CPU that fits in a slot, carefully insert it until it's firmly seated.

    A reminder: All CPUs need cooling. If a heatsink or fan isn't built in, purchase and install one. Without it, your new CPU will self-destruct in minutes.

    4. Install the New Motherboard
    Slide the new motherboard into the case. You'll know it's in the correct position when the mounting holes align.

    Mount the motherboard, using the screws you removed in step 2. Just "snug up" the screws; screwing them in too tightly can damage the motherboard.

    5. Reinstall Cards and Cables
    Reinstall the cards and cables that you removed. Don't rush through this step! Work slowly and carefully, avoid bending pins, and double-check to see that everything is correctly connected.

    IMPORTANT: Don't forget to connect the CPU fan's power cable to the motherboard.

    Reinstall your PC's add-in cards, securing them with the screws you removed earlier.

    Reconnect the mouse, keyboard, monitor, printer, and any other external devices you may have, but don't put the cover back on your PC until you're absolutely sure that everything's working.

    Finally, plug in the AC power cable.

    Finally:  Start if UP!!!
    Turn on your PC. If it beeps and you see messages on the screen, that's a positive sign. Expect the new hardware to confuse Windows initially. The OS should automatically reconfigure itself, but don't be surprised if Windows restarts itself several times during the process.

    If nothing happens--or if your PC hangs part of the way through start-up--turn off your PC, disconnect the AC power, recheck all the connections, and start the system up again. If it hangs again, contact your motherboard maker's tech support. Dead-on-arrival motherboards, CPUs, and RAM modules are rare, but they do occur.
