Windows XP Error After Replacing Motherboard

Motherboard is the main circuit board, which contains all the basic circuitry and components of the computer system. The main components of motherboard include memory, BIOS, microprocessor, mass storage device interfaces including hard drive, interconnecting circuitry, expansions slots, serial and parallel ports and the controllers which control peripheral devices. All the chips collectively form chipset.

If the motherboard is replaced in a Windows XP system, this is needed that the replaced motherboard must contain the IDE controller that has the same chipset as of the earlier used motherboard. However, if they differ, Windows XP may prompt an error when you start the computer system after motherboard replacement:

"STOP 0x0000007B INACCESSIBLE_BOOT_DEVICE"

An IDE or Integrated Drive Electronics controller is what acts as an interface between motherboard's bus or data paths and the computer storage device, such as hard drive. Today, for EIDE or IDE hard drives, IDE controllers are still there on the motherboards.

IDE controller difference may not let the system to start. In order to resolve this issue, we need to check whether the new IDE controller is detecting the hard drive size as the same as was detected by previous IDE controller or not.

• If the new IDE controller is detecting the hard disk as the same size, we need to carry out in-place upgrade (reinstallation) of Windows XP.

• However, if the size doesn't come out to be same, we need to repartition and format the hard drive and then reinstall Windows XP operating system. It requires the data to be backed up first to avoid Data Recovery requirements.

Data that gets lost due to formatting still remains on the hard disk's data area, if it has not been overwritten. So if the backup has not been taken or if it fails, Data Recovery Software can recover lost data. Recovery Software uses powerful scanning algorithms which examine the failed hard drive and help extracting the possible lost information.

Replacing Your iPhone 3G Motherboard - Worth It or Not?

For anyone who owns an iPhone (or any electronic device, for that matter), it is a safe assumption to make that there will come a time when some part of it will malfunction or break all together. When most people get a new iPhone, they treat it with the utmost care, handling it more like a puppy or a baby than like a machine. By being diligent about keeping it in a protective case and not throwing about will nilly, people try to preserve its brand new condition for as long as possible, fearing every little scratch as if it were the end of the world. Of course, it is only possible to maintain this for so long. After a while, the iPhone is bound to get dropped. People become careless and leave their phones plugged in too long, which overcharge them and run down the battery, or they leave it on the table while they are eating and end up accidentally spilling a drink on it.

This carelessness, combined with the natural destructive effect that time has on anything, makes it practically inevitable that something will go wrong, whether it is a cracked screen or a wrecked iPhone 3g motherboard. When this happens, you have to ask yourself if the time has come to completely replace your iPhone, or whether your current device can be salvaged. Depending on the specific problem, you may be able to save a lot of money by simply having the broken part fixed or replaced, rather than starting from scratch with a new phone.

Say, for example, that it is your iPhone 3g motherboard that breaks. The first thing that you ought to consider is the cost of repairing the part. If your phone is still under warranty, then this fix should be free for you. If your warranty has lapsed, however, labor costs can be quite high. If you are a hands on type of person with a lot of experience with fixing and tinkering with electronics, then you may be able to do the repair yourself and save yourself the cost of paying a professional to do it for you. But if you are not very good with these kinds of projects, you may end up doing more harm than good, in which case it might make more sense to get a new iPhone 3g motherboard.

Remember that the motherboard is like the brain of your phone, and when you get a new one, most of your old information will be lost. In this way, getting a new iPhone 3g motherboard is basically the same thing as getting a new phone (especially if nothing else is broken or defective), only it costs less. These days, there are a lot of companies that specialize in selling replacement parts for iPhones. This can be a very budget friendly solution to your problem. If you decide to go this route, make sure you do some shopping around first to find the company with the best deals on iPhone 3g motherboard replacements.

iphonepartspro.com provides all of the parts to fix your broken iPhone. The selection at iphonepartspro.com is the best on the Internet.

Home PC Repair - Replacing Your Motherboard

If do it yourself projects generally scare you take heart. This ones pretty simple. The good news is that Home PC repair - replacing your motherboard is pretty basic and quite hard to mess up.

Familiarize yourself with how the PC comes apart. Where are the screws that allow the side panel to be removed? Are their multiple panels that can be removed? Do an online search for how to build a computer so that you can become familiar with how the parts of the PC should look.

The most important thing to know about replacing a motherboard is to get a socket that matches the CPU you will be using and the type of RAM you intend to use. If you are going to use the same CPU and RAM you will need to get the same socket motherboard that also can take the RAM you currently have. Finding this information can be done very easily by doing a search at newegg for your socket and ram followed by motherboard. For example; "socket 775 ddr2 motherboard" in their search bar.

You will also need to get the correct size of board for your PC case. These numbers are easiest to find by doing a search of your existing motherboard model numbers.

When you have your New Motherboard: READ THE MANUAL that came with the motherboard. Even if you don't understand it. It will all make sense when you start pulling things apart.

1. Disconnect the Power to the computer.

2. Place the PC on a towel to keep from scratching the case.

3. Remove the side or access panel

4. Locate the parts of the PC such as the power supply, CPU cooler, RAM modules, etc.

5. Mark the wires and their corresponding positions. Make a map of where they plugged in on the board. This step is more for your mental well being than a necessity.

6. Start unplugging all the wires that are plugged into the board. You will notice that each wire has a unique style plug. This will keep you from confusing things when you reassemble.

7. Release the strapping mechanism on the CPU cooler. Gently twist the CPU cooler in a circular motion without pulling up. This is to break the seal of the CPU thermal paste between the cooler and the CPU. Then gently pull up on the CPU cooler while making gentle twisting motions. (sometimes the paste will create a vacuum seal between the CPU and cooler.)

8. Remove as much thermal paste from the top of the CPU without letting any pieces of paste fall between the CPU and clamp down bracket. If a piece falls in you can remove it after the CPU is out of the socket.

9. Unlock the CPU hold down clamp and carefully remove the CPU. Place the CPU in a safe place so you do not damage the pins. If you bent some pins during removal -very carefully bend them back into position. If you broke some pins off your CPU is scrap, order a new one.

10. Remove the RAM sticks by pushing down on the tabs at each end. These tabs will push the RAM up and out.

11. Remove any cards from the PCI, PCIe slots. These are the slots that give you places to plug components into from the back panel. Some PC's will have cards here, other not.

12. Locate all of the mounting screws that hold down the motherboard and remove them with a tool. Usually, a screw driver but sometimes other tools are necessary.

13. Gently remove the old motherboard from the case.

Before you place the new board into the case count the holes in the board and make sure you have the right number and placement of mounting holes. If a support stud would touch in the wrong spot on the board it could short out the board.

14. Reverse the order to install the new board.

15. Use a magnifying glass and work light to make sure your front panel wires are in the correct positions. Note the markings on the ends of the wires to place them properly. The board will be marked next to the places where the wires should plug in. Just read, you won't mess it up. Then double check your work.

16. When you are done put the lid back on and power the PC up. Depending on the type of motherboard you may need to set your RAM voltage and other settings within the BIOS. Use the motherboard manual to access the BIOS features and make these changes. Most of the time though you will be able to just power it on and it will work without any changes.

That's basically it!

You just did a Home PC Repair - replacing your motherboard! Now pat yourself on the back and take yourself out to dinner. You just saved about $150 dollars.

Computer Power Supply & Motherboard Replacing

If your computer is acting up, chances are it may need a new power supply or motherboard.

In this article you'll learn how to replace these parts.

Most computer cases come with a power supply; however, in some cases it is not included, it may be necessary to purchase one separately.

The power supply is a metal box and it supplies low voltage power to the various circuits inside the computer. It also has a fan inside to keep it cool.

The power supply has 4 to 7 connectors that will plug into the mother board and disk drives.

Orient the power supply with its fan so that the fan faces the back of the system case, and place into position.

Fasten it to the case with screws using a non-magnetic screwdriver only!





You are now ready to install the motherboard, also known as a main or system board.

There are 2 types, depending on what system you want to build.

The AT socket 7 and the ATX module slot 1 each using their own power supply and case.

If you are upgrading your present system you'll want to make a diagram of all connections before you remove them.

Carefully remove each expansion card from it's slot, it will be secured by a single screw.

It's ok to seesaw the card end-to-end slightly to loosen it, but don't bend the card sideways.

Set the cards on the power supply with paper separating them.

Leave all cables connected.

After making your diagram remove all cables to the motherboard.

Locate and remove all mounting screws.

Now you are ready to install the new motherboard.

Using the hardware that came with your computer case you will mount the motherboard.

Orient the board so that the power supply sockets are facing the back right corner.

Mount brass and plastic standoffs in the case to match the holes in the board.

Secure the motherboard with screws using non-magnetic screwdrivers only!

For an AT style board connect the two power supply cables to the motherboard.

The black wires go in the center next to each other.

Tilt the connectors away from the power supply and align the hooks on the connectors with the space on the sockets between the metal prongs and the back of the sockets.

Tilt connectors toward the power supply until they are vertical and slide them down over the prongs.

For an ATX style you will only have 1 connector.

Your new motherboard comes with disk drive cables; these are the flat Grey cables with a dotted colored edge, usually red. There are cables for a hard disk drive and a floppy disk drive.

The hard disk drive cable is wider than the floppy disk drive cable.

If you are replacing your current motherboard use your original cables.

If you look closely at your motherboard you will notice that all connectors are marked in white lettering.

Insert the wider hard drive cable in to the PRIMARY IDE socket, the colored edge will go near pin # 1.

Insert the floppy drive cable into the floppy disk drive socket, the colored edge will also go near pin # 1.

There are several wires coming from the computer case, these wires lead to the indicator lights and the speaker.

If you are using an ATX case power supply and motherboard you will have an additional wire that's marked P S for power switch. This wire will plug directly in to the ATX motherboard.

If you're working with an AT style, plug the lead for the power supply directly into the power switch in the computer case.

The remaining wires are marked on their connectors as follows:

TURBO LED

TURBO SWITCH

SPEAKER

RESET

KEYLOCK

And IDE or HD for HARD DRIVE

These wires connect to their associated sockets on your motherboard.
