An error describes any issue that arises unexpectedly that cause a computer to not function properly. Computers can encounter either software errors or hardware errors.

There are several types of errors and each have hundreds of variations. To fix a computer error, you must first identify the type of error and the source.

Software errors are the most common types of errors on a computer and are often fixed with software updates or patches

Hardware errors are any defects with hardware inside the computer or connected to the computer. Although some hardware issues can be fixed with ffirmware updates, most of these errors are resolved by replacing the defective hardware.

Windows Errors

The POST beeps

This probably is the first error you could encounter after turning your computer. If all the vital components inside the computer are running fine, you will hear one beep (or two, depending on your motherboard’s manufacturer). One beep technically means that your computer has successfully passed the POST (Power-on self-test). If however you hear more than one beep, then it means that certain hardware of your computer is not functioning properly. Depending on the manufacturer of your computer’s motherboard (and also, BIOS version), any extra number of beeps that you hear suggests a faulty hardware. It could be anything from an out of power CMOS battery to a non-functional graphics card.

Blue Screen of death (BSoD)

Doesn’t matter which Windows operating system you are on, one thing that you must have encountered a couple of times by now is the Blue Screen of Death or BSOD Unlike most errors, there is no real-time escape from this error. You can’t press ESC to avoid it, or Ctrl + Alt + Del to fix it right away. This error usually occurs because of recent hardware or software change that you might have made on your computer. After restart, you should unplug any new device that you had attached to your computer, or uninstall any new software while booting in through Safe Mode

To tackle these situations, you can also use a nifty freeware tool Nirsoft Bluescreen view The app looks into the system dump files and logs to figure what might have caused the problem. Alternatives include Who crashed and Reliability monitor

Virtual Memory Too Low

It’s another common error to bump into. It usually occurs when you have an insufficient amount of RAM or, an application is eating up or leaking your precious memory. Computer uses smart ways to deal with programs, it either provides them the real actual memory or something called Virtual memory, which is essentially your hard-drive memory being used in place of physical memory. To resolve this error, you need to buy some more RAM chips.

If you think your existing RAM(s) are enough to bear the amount of work you do, then, increase the size of the pagefile. To do that, go to Control Panel, System and Security. Click on Advanced system settings, and from the Advanced tab, inside the performance pane, click on settings. Usually, it is suggested to have the size of PageFile about 1.5 to 2 times your RAM memory.

The missing DLL files

It is pretty common to cite a missing DLL message. What this error usually means is that while execution of a program, one of the required files (.dll in this case) was nowhere to be found. You can fix this error by reinstalling the software, or if it is a system file, you can search for that file online and get a copy of it. It is not necessary that the replacement file will always work, and secondly, make sure that the website from which you are downloading the file is trustworthy. Usually these errors are caused by viruses, so you may want to try a better anti-virus suite.

Device errors

If a device has recently stopped working, it could be because of some glitches in its driver module. To figure out what is wrong with that device, you will need to go to the Device Manager. To reach there, click on the start menu and type devmgmt.msc. Now locate the device, right click on it, and go to its properties. Click on the ‘Update Driver’ button. If updating the driver doesn’t resolve your problem, click on the Device Status, you will find an error code. Search that code on the web, and you will find links to an ample number of forums including Microsoft’s support site explaining and providing the solution for your problem.

Fatal Exception errors

In computer a lot of programs and hardware share memory and other resources with each other. If for some reason, a program doesn’t get its request fulfilled, you will get an error saying ‘unhandled exception’ and the program might even terminate. In worst scenario, it could even cause the computer to shut down. If you have seen that error, you can visit the webpage of Microsoft’s list of fatal errors and identify your problem.

System Error Codes

Software programmers follow a protocol to assign error codes to tell end users, and IT support about that error and what that error means. You can go to Microsoft’s support site where they have documented all the error codes and what those errors mean. For example, Error “22” points to “ERROR_BAD_COMMAND”, which means that the command you have entered is unknown to the program. Whereas, error “225 (0xE1)” is “ERROR_VIRUS_INFECTED” that means the program wasn’t able to complete the operation because the file contains a virus or any other potential unwanted program.

Browser Errors

We have many varieties of 4xx and 5xx errors that you could come across while surfing the web. While some of the errors, like 404 (Page Not Found) and 408 (Connection timed out) are usually not your browser’s fault but the server you have pinged. But there are few errors that could be blamed on your browser.

Error 403

The error 403 means that your computer has made the connection successfully, but you don’t have the required credential to view the page. Look for authorization/authentication details and try again.

Error 501 or 505

This error means that either your browser is outdated and hence does not support the version of HTTP protocol. Or, your browser doesn’t have the required plugins, like Java or Flash that are essential to display the content of the page. Both way, you could update your browser and since all the popular browsers are now laced up with the basic 3rd party services, your browser should be able to display the content. Or, you can install the required plug-in by visiting their official websites.

Error 406

This error means that your computer (needless to mention, the browser) doesn’t have the required software to view the content. Make sure to download the required software and that should fix the problem.

The Code 43 error is one of several device manager error codes It’s generated when Device manager stops a hardware device because the hardware reported to Windows that it’s having some kind of unspecified problem.

What Does a Code 43 Error Mean?

This generic message could mean there’s a true hardware problem or it could simply mean that there’s a driver error that Windows can’t identify as such but that the hardware is being affected by it.

It will almost always display in the following way:

Windows has stopped this device because it has reported problems. (Code 43)

Details on Device Manager error codes like Code 43 are available when you view a device start up in its properties.

The Code 43 error could apply to any hardware device in Device Manager, though most Code 43 errors appear on video cards and USB devices like printers, webcams, iPhones, and related peripherals.

How to Fix a Code 43 Error

Follow these steps in order, to resolve a Code 43 error. Because this message is generic, standard troubleshooting steps come first.

1. Restart your computer if you haven’t done so already.There is always the chance that the error Code 43 you’re seeing on a device was caused by some temporary problem with the hardware. If so, a restart of your computer might fix the Code 43 error.Some people have also reported that powering off their computer completely (not just a restart) and then turning it back on has corrected their Code 43 warning if it sources from a USB device. In the case of a laptop, turn it off and remove the battery, wait a few minutes, and then put the battery back in and start the computer.
2. Plug the device into a different computer and then properly eject it from there. Plug it back into your computer to see if it fixes the Code 43 error.If you have another computer to test this on, be sure to try this before moving on to the more complicated steps below.
3. Did you install a device or make a change in Device Manager just before the Code 43 error appeared? If so, it’s possible that the change you made caused the Code 43 error. Undo the change if you can, restart your PC, and then check again for the Code 43 error.Depending on the changes you made, some solutions might include:
   • Removing or reconfiguring the newly installed device
   • Rolling back the driver to a version prior to your update
   • Using system restore to undo recent Device Manager related changes
4. Disable the device  and then re-enable it This step provides Windows with a chance to take a fresh look at configuring the device.This might sound like a very simple fix, and that’s because it is. However, this procedure might be all the computer needs to correct the Code 43 error.
5. Re-install the drivers for the device Uninstalling and then reinstalling the drivers for the device is a possible solution to a Code 43 error.If a USB device is generating the Code 43 error, uninstall every device under the Universal Serial Bus controllers hardware category in Device Manager as part of the driver reinstall. This includes any USB Mass Storage Device, USB Host Controller, and USB Root Hub.Properly reinstalling a driver, as in the instructions linked above, is not the same as simply updating a driver. A full driver reinstall involves completely removing the currently installed driver and then letting Windows install it over again from scratch.
6. update the drivers for the device: It’s also possible that installing the latest drivers for the device could correct the Code 43 error.If updating the drivers does remove the Code 43 error, it means that the stored Windows drivers you reinstalled in Step 4 were probably damaged or were the wrong drivers.
7. Install the latest windows service pack: One of Microsoft’s service packs or other patches for Windows might contain a fix for whatever might be causing the Code 43 error, so if you’re not fully updated, do so now.
8. Update BIOS: In some situations, an outdated BIOS could be causing a specific issue with a device that’s making it report a problem to Windows—thus the Code 43 error.
9. Replace the data cable that connects the device to the computer, assuming it has one. This potential fix for a Code 43 error is most often useful if you’re seeing the error on an external device like a USB or FireWire device.
10. Purchase a powered USB hub if the Code 43 error is showing up for a USB device. Some USB devices need more power than the USB ports that are built into your computer can provide. Plugging those devices into a powered USB hub solves that challenge.
11. Replace the hardware. A problem with the device itself might be causing the Code 43 error, in which case replacing the hardware is your next logical step. In most cases, this is the solution to a Code 43 error but try the easier, and free, software-based troubleshooting ideas first.If you’re positive that a hardware problem isn’t causing the Code 43 error, you could try a repair windows installation; If that doesn’t work, try a clean install of windows:We don’t recommend doing either before you replace the hardware, but you may have to give them a try if you’re out of other options.
12. Another possibility, while not very likely, is that the device is incompatible with your version of Windows. You can always check the Windows HCL to be sure.
