Quite often the system may have a conflict when trying to connect some new equipment. One such example is code 45 "The device is not connected to the computer." This article will discuss the causes of this problem, as well as ways to solve it.
Signs of a specific error
Often, the message that this or that error has occurred does not appear immediately. The computer may simply start to work not as stable as it was before. The following are signs that your device is experiencing this particular error:
- Periodically, it may freeze for a few seconds. This happens for no apparent reason, or after you tried to connect a second monitor.
- Another sign can be an extremely sluggish system response to mouse use. Keyboard input is also difficult.
- General slowdown in Windows.
- When trying to connecthardware device, the computer freezes and gives a "Code 45" error. After that, the window of the currently running program is closed.
It is worth noting that this phenomenon often occurs when trying to install or run a program developed by Microsoft itself. Also, the code may occur at the start or shutdown of the device. Sometimes the inscription "Error 45" may also appear during the installation of the operating system on a new or old computer.
Let's look further into why this happens.
What are the reasons
Due to the complexity of the computer, it is quite difficult to understand what can cause an error or malfunction. Here are just some of the assumptions that can provoke a conflict situation:
- Let's say you decide to update your printer driver. However, it turned out to be damaged or outdated. Therefore, it cannot be installed. It's worth noting that this particular variant is the most common among all cases of the "This device is not currently connected to your computer" message.
- Another option related to drivers may be a conflict when installing new hardware. The software may have a different bit depth or may not be compatible with your specific device model.
- The computer could have been infected with a virus that changed or even corrupted any system files and drivers that come with themcontact.
- Assume another technical option. Before connecting a second monitor, you did not make sure that it was working. As a result, a message appeared that the device was not connected to the system.
- The most serious problem that may require you to reinstall Windows is damage to the registry of the operating system.
We figured out the possible causes of this error. You can move on to known ways to fix it.
Computer scan
When an error code 45 appears, you need to check the device for the possible presence of various malicious software that can damage or modify system files. The verification process can be performed both by the standard Windows Defender and by any additional programs - antiviruses. As an example, you can use Emsisoft Anti-Malware.
Cleaning up obsolete and temporary files and programs
It may very often happen that programs are installed on the computer that have not been used for quite a long time. To fix this, just do the following:
- Click the Start button and go to Windows Settings.
- Here you need to select the section called "Applications".
- After moving to a new window, simply sort the applications by specific locations or by the "All Drives" category.
- In the list that appears, select and remove all unnecessary programs.
This should help with error code 45.
It may also happen that when uninstalling some software, defragmentation occurred. As a result, many files ended up in different folders on the disk. This situation greatly complicates their search and elimination.
This problem can be easily fixed using the Revo Uninstaller Pro utility. To eliminate temporary files, do the following:
- After starting the program, click on the "Tools" button (on the top panel of the window).
- In the list that opens, select the line "Junk file cleaner".
- After switching to a new tab, start the directory selection routine by clicking on the "Scan folder" button.
- In the new window, select the desired disk and confirm the action.
- In the list that appears, click the "Delete" button. It is in a small box above the tabs.
Updating drivers
As mentioned earlier, error code 45 can be caused by outdated or corrupted drivers. In this case, you need to make sure that the devices connected to the computer have the latest versions of this software. There are two ways to update. The first is done through Windows itself:
- Enter the name "Control Panel" in the search bar and select the standard application.
- In the window that opens, find the section "Dispatcherdevices".
- After switching to it, a list of all devices and drives connected to your computer will open.
- To update drivers, just right-click on the device icon. In the list that appears, select the appropriate section.
Second option. Let's say you want to update your printer driver. To do this, follow these steps:
- In a browser, go to the website of your hardware manufacturer.
- Find the driver update section.
- Among the list of devices available for updating, find yours.
Rollback to previous version
If you encounter an error with code 45, you should try to roll back the operating system to the previous version of Windows that was before the update. Thanks to this, the computer will be able to return back all the changes that led to the appearance of this error. To complete this task, you must do the following:
- Launch the Start menu and go to Windows Settings.
- In the settings window that opens, find the section called "Update and Security" and go to it.
- In the list on the left, select "Recovery".
- You will then be prompted for a password.
- After confirming that you are the owner of the device, the rollback process will start. To do this, simply follow the instructions.
When you return the system to a previous version of updates, your fileswill not be deleted. This action will simply return the system files to the state they were in before the changes were made.
Reverse action
You can try to do it a little differently. Instead of rolling back the system to the previous version, you need to install all available updates for the current operating system. However, this can only be done if you do not already have the latest version installed. To check if installation is possible, do the following:
- Launch the Start menu and go back to Windows Settings.
- Here, open the section called "Update and Security".
- You will automatically open the "Update Center" section.
- In the main field, select the line "Additional parameters".
- In a new window, check if you have the option to receive updates enabled. If not, enable it and return to the previous section.
- Click on the button to check for updates and install them if any are found.
Check hard drive
Another way to resolve error code 45 is to check your hard drive for errors or malware. To perform this check, you must follow the following instructions:
- Launch the "Start" menu and type "Command" in the search bar.
- Simultaneously holding the "Ctrl" and "Shift" keys, pressenter key. A new dialog box will open.
- Here you must confirm your choice by pressing the "Yes" button. The console window will launch.
- Type "chkdsk /f" here and confirm with the enter key. After that, the process of scanning the hard disk and searching for all possible damage will be started.
- After that, follow the instructions that will appear on the monitor screen.
Checking random access memory (RAM)
Errors or malfunctions in RAM can also be the cause of error 45. It is worth noting that almost ten percent of all Windows errors are associated with RAM corruption. If the memory sticks were purchased recently, it is recommended to perform a simple check:
- Remove them from the system unit. Return the old ones (if they exist and work) or start the system without RAM. The BIOS will start beeping, but there's nothing to worry about. It reports that RAM was not found.
- Start the system and check if the error occurs again. If yes, then it is worth trying one of the methods above. If it is not there, you can return the new memory bars that you removed.
You should also turn to special software that will check the he alth of the RAM and the presence of its damage. Memtest86 can be noted among such utilities. If the program detects problems with the RAM, you need to take care of replacing the faulty part of the system.
From a clean slate
If none of the above methods solved the problem, all you have to do is uninstall your current operating system and reinstall Windows. To avoid data loss, it is necessary to make backup copies of all files and documents that are on the computer.
If reinstalling the operating system did not help fix error 45, you should pay attention to the hardware of the system unit. If possible, test by replacing parts one at a time to determine which one is causing the device connection error.
