Replace Your Motherboard

Replace Your Motherboard


Learn how to transplant your PC's most important component.

By John Mwingira



If you are looking to use an updated processor, want to add some newer components that require the latest technology, or have shorted out your motherboard with an incorrect audio cable (not that we're speaking from experience), changing your motherboard is the way to go. Though the process looks daunting, it requires little more than a Phillips screwdriver and some patience. Here's everything you need to know.



Step 1: Assess the situation Before you pull out your toolkit (or even your credit card), do a bit of reconnaissance inside your PC. Some things to keep in mind:
If your case is a proprietary one from a major vendor, it might not easily house a replacement board. And if it's a small-form-factor PC, you won't be able to put a larger ATX motherboard into it. Make sure your case supports the form factor (ATX, MicroATX, and so on) of your new board.
Many older motherboards require a 20-pin main power cable from your power supply, but recent boards require both a 24-pin connector and a separate 4-pin one. Your motherboard won't work if improperly powered, so a new power supply could be in order.
Do your optical and hard drives connect via IDE (usually with ribbon cables) or via newer Serial ATA (thinner cables)? Many newer motherboards have only one IDE port (which supports two drives), whereas older boards have two. If you have more than two IDE drives, be sure your new board has a second IDE connector.
What kind of processor, RAM, and graphics card will you be using? What was top-of-the-line a few years ago could be obsolete today. AGP graphics cards certainly are—most newer motherboards lack slots for them, replacing them with PCI Express (PCIe). Processor socket technology and RAM design have also changed. If you don't want to buy all new components, make sure yours work with the new motherboard. Not sure what you have? A free utility like CPU-Z can suss it out.
Be mindful of Windows' licensing requirements—replacing a motherboard can necessitate reactivating Windows. Depending on whether you have a full-retail or OEM version, you may have to repurchase Windows.


Step 2: Cleaning up Here, you'll have to make a choice: Install your new motherboard and keep your existing Windows installation in place, or take the opportunity to wipe your boot drive and start from scratch. If you do the second, have your Windows and application discs handy. Either way, you'll want to back up your data.
Open your case's side and take photos of your PC's rear panel and interior, or label all the cables. (Sticky notes work well.) Many of today's connectors are color-coded, but if yours aren't, this precaution could prevent frustration later.
Once you have all the correct equipment (and a screwdriver), it's time to begin. Disconnect the PC's power cable and everything attached to its rear panel (which is part of the motherboard). Then, turn the case horizontal to tackle the interior.
Ground yourself, either by using an antistatic wrist strap or by touching the metal chassis. Then remove any cards in your old motherboard's expansion slots. Remove the screws securing them to the chassis, then pull the cards straight up and out. (For a PCIe x16 card, you might need to depress a lever on the slot before doing this.) Place them on a clean, static-free surface.
Next, detach all cables and wires connecting your motherboard to the PSU, case front panel, optical and hard drives, or other components (such as fans). For the big PSU power-cable connectors that plug into the motherboard, squeeze a lever on one side to release the connector; most other cables should pull out easily.


Step 3: The great swap-out Now for the switch. Locate the screws holding down the motherboard (usually six or nine), and remove them. Once done, the motherboard will lift out. To protect it, place it in the antistatic bag your new board came in.
Next, pop out the I/O panel—the metal rectangle with the port cutaways—attached to the case. Your new motherboard will come with its own, designed for the board's port arrangement. When inserting the new I/O panel, apply enough pressure around the edges to hear the clicks.
It's more convenient to install the processor, its cooling fan, and the RAM before installing your new motherboard. RAM is easy: Lower the levers on the RAM slots, line up the notch in the module with the slot's protrusion, then press the chip until both levers lock. If you're using two RAM chips, put each in an identically colored slot—this dual-channel architecture increases performance.
Processors are more complicated. Intel's and AMD's designs vary, sometimes between their own lines, but today's processors and sockets are keyed so it's hard to orient a CPU incorrectly. That said, never force anything: If your processor resists when you engage its locking mechanism, you could damage it. Once it's in place, apply a layer of thermal paste to the CPU, and attach the fan to the board, covering the CPU. Don't forget to plug in the fan's power cable to the board's "CPU fan" header.
If your new motherboard is the same size and shape as the old, you shouldn't need to adjust the standoffs that keep the motherboard from touching the case. If, however, you're upgrading from a smaller board to a larger one, you might. Place the motherboard in the case, lining up its holes with the standoffs. Make sure there's a standoff for every hole, and vice versa. After the standoffs are settled, gently place the motherboard, fitting its ports through the I/O panel. Once the holes are directly over the standoffs, secure it using the screws removed earlier

How to Fix High CPU Usage

About High CPU Usage
CPU Usage in Task Manager is 100%
A High CPU Usage reading indicates that the computer's central processing unit is running at max level or is above normal level for the number of applications running. Slow performance, hang-ups (freezing), and random shutdowns are symptoms of high CPU usage. The CPU (processor) processes all of the instructions for programs. The rate at which CPU's process instructions in cycles which are measured in hertz (Hz), commonly extrapolated to megahertz (Mhz) and gigahrtz (Ghz). A given CPU has a maximum number of cycles which can be produced per second. Simply put, the CPU can only handle so much before it becomes encumbered by the number of processes and becomes slow.
Is your computer running extremely slow? Open the Task Manager (Ctrl+Alt+Del) and check the CPU usage. If your CPU usage stays at 100% all the time, there is a serious problem. Typically, your processor usage shouldn't go over 50% unless using large applications such as video games or media editing programs.

Common Causes of High CPU Usage
The factors that contribute to high CPU usage and slow performance are varying. The problem may stem from hardware failure or software error or both. In order to diagnose the problem accurately, it's a good idea to know the common causes of high CPU usage so you might better identify the root cause. Constant, high CPU usage is not normal. If your computer performs slowly and displays a high CPU usage percentage in the task manager, there is an underlying problem that is causing the processor to run at such an extreme speed. Diagnostic troubleshooting is required to accurately identify the problem, but these are some of the common causes of high CPU usage:
High CPU Usage May Be Caused By...
There are other events which can result in high CPU usage, but these are some of the most common. We've covered many of them with other articles or programs linked above. The rest, we have covered in a detailed guide: Manually Fixing High CPU Usage. Keep in mind, these guides are meant for users with some administrative skill and not following them properly can lead to serious issues.

How to Easily FIX High CPU Usage
Most CPU Usage issues can be traced back to an overload of processes running, and too little resources to handle all of them. This does not mean that your computer has to be like this! Rather, you need to find which processes are clogging up your computer's performance and remedy them. While this can prove tough to do manually, automated programs such as FixCleaner can turn this chore into a walk in the park.
FixCleaner is a system optimizer that can seek out issues with your computer's configuration. It's one-click interface allows even the most novice computer users to take advantage of it's high-powered optimization engine. FixCleaner is mainted and supported by SlimWare Utilities Inc, an award-winning software company that has been covered in numerous high-level media publications.
