Motherboard failure diagnosis and ledderhose disease surgery solutions

For people who didn’t grow up building computers and who haven’t learned the architecture of these ubiquitous machines, let’s have a brief tutorial about the components of a ledderhose disease surgery personal computer and where the motherboard fits into the scheme. Conceptually as well as physically, computers have three basic kinds of components: the processor, the storage (memory and permanent storage as well), and the input/output (I/O) system. The processor is your CPU, probably a microchip from AMD or Intel, along with your GPU if you have one. The storage is your RAM and your hard drive(s) – where you put your information. Finally, the input/output system is all the elements that let you interact ledderhose disease surgery with the computer – the video card and monitor, the keyboard, the mouse, and so on.

So where does the motherboard fit into this system? Well, the motherboard isn’t conceptually important, but it’s physically crucial. It’s the circuit board (really a set of circuit boards put all together) on which all these other components are placed. The CPU plugs into the motherboard, where it communicates via a channel called a “bus” with the hard drive, the memory, the keyboard, and all the rest. The memory is generally placed directly on the motherboard; the hard drive is probably in its own area, but it connects to a hard drive controller which is ledderhose disease surgery located, you guessed it, on the motherboard. The keyboard and the USB slots are wired right into ledderhose disease surgery the motherboard. The video card plugs into the motherboard, usually with its own bus.

Motherboards are historically the most difficult pieces of hardware to ledderhose disease surgery diagnose because, in most cases, you have to rule out every other piece of hardware ledderhose disease surgery that is connected to it. There aren’t usually any real signs of failure, other than your computer suddenly turning into an expensive doorstop. A hard drive might give you signs of failure, such as blue screens or lost files, but a motherboard will just suddenly stop working. That being said, here are some things you can try first to ensure ledderhose disease surgery the problem is with your motherboard instead of another hardware ledderhose disease surgery component. Diagnosing the Problem

There are some easy troubleshooting steps you can take to ledderhose disease surgery determine if your motherboard is going bad. Below we break the troubleshooting procedure into two categories: 1) What to check if the computer still passes the POST ledderhose disease surgery and boots (or attempts to boot), and 2) what to check if the computer no longer passes the ledderhose disease surgery POST or does not even turn on. Computer Passes POST and Boots OS

Harddrive(s): Are files taking a longer time to transfer? Are you seeing errors or blue screens? Has boot time increased significantly? Do you hear any clicking or loud whining noises? If the answer to any of these questions is yes, your harddrive may be going bad. It will be worthwhile to run the diagnostic utilities in ledderhose disease surgery Windows and/or from the drive’s manufacturer. Also, see our companion article on Hard Drive Failure: Warnings and Solutions.

Power Supply (PSU): A failing or insufficient power supply (or one that is operating out of spec) can quickly cause a system to become unstable and also ledderhose disease surgery potentially cause damage to the other computer system components. Ensure you have the proper power supply for your system, and double check the supply’s voltages to make sure they are operating in line ledderhose disease surgery with their rated output (the voltages can easily be monitored in the BIOS or ledderhose disease surgery in software utilities supplied by motherboard manufacturers). If you are still unsure, please also read through our article on power supply troubleshooting.

Finally, also a brief word on system cooling: In many instances, errors are experienced due to improper cooling or even cooling ledderhose disease surgery failure in a computer system. If any of the system’s components are operating out of spec due to overheating, system instability can result. A visual inspection of the system is suggested to make ledderhose disease surgery sure that all components are seated properly and being cooled ledderhose disease surgery sufficiently (i.e. case and component fans are operating normally). Temps can also be monitored for anomalies inside the operating ledderhose disease surgery system using a wide variety of tools – we suggest a few free ones you can use in ledderhose disease surgery our article on PC temperature monitoring. Computer Does Not POST or Turn On

The first to thing to do is perform a brief ledderhose disease surgery visual inspection on the system itself. Are all components seated properly? If the system turns on, are all the fans spinning? If the motherboard has a visual LED indicator, what color is it (usually green means everything is OK)? If there is any doubt, try re-seating components as necessary and try starting the system again. Some more modern motherboard will even have LEDs for individual ledderhose disease surgery components. For instance, if there’s a problem with your RAM or CPU, you should be able to find an LED near that ledderhose disease surgery specific component, indicating if there’s a problem or not (again, green usually means everything is OK).

The second thing to do is confirm whether the motherboard ledderhose disease surgery produces error (or beep) codes when trying to start the system up with key ledderhose disease surgery components missing (e.g. CPU, RAM, video). This assumes, of course, that the system still turns on. For example, if you remove the RAM and start the computer, does it respond with error beeps? Do note that some modern motherboards no longer support beep ledderhose disease surgery codes (please consult the manual of your motherboard to make sure ledderhose disease surgery yours does). For more details on different motherboard beep (error) codes and what they mean, please consult these resources here and here.

In some cases it’s actually the power supply that’s bad. Power supplies can appear to still be functioning, as the power supply fan may still run, as well as the CPU fan and any lights that ledderhose disease surgery you might have on your computer. But just because these parts activate, it doesn’t mean the power supply is supplying enough juice to ledderhose disease surgery the motherboard or other parts of the computer.

Finally, there are two more quick tests you can perform. The first and quickest is to reset the board’s CMOS by removing the battery . The second is to test the components outside the PC ledderhose disease surgery case. We have a great step-by-step guide over on the PCMech Forums that will take ledderhose disease surgery you through these steps to determine if you have a ledderhose disease surgery short or faulty component. It’s Dead – Now What?

Unfortunately, if going through the diagnostic procedures above did not help, it may be time for a new motherboard. There’s no real way to tell how your motherboard died. Electronic parts experience wear and tear like anything else. All parts do eventually die; it’s a normal thing, though sometimes motherboards can die from being shorted out by ledderhose disease surgery a low-quality power supply. Again, this is something you can determine by putting a new ledderhose disease surgery and hopefully higher quality power supply in your machine and ledderhose disease surgery seeing if it runs or not.

If you know your motherboard is dead, as an alternate route, you could try and repair your motherboard, but it’s no easy task. You would need a solid understanding of electrical components, such as capacitors, for instance. You’d need to not only understand the risk of electrical ledderhose disease surgery shock, but also that it’s difficult to check if a capacitor is dead on ledderhose disease surgery modern motherboards. However, if you want to give it a go, Tom’s Hardware has put together an excellent and well-researched guide on replacing capacitors.
