Mistakes operating system that affect the operation of peripheral devices are detected after loading the main OS. Check the keyboard in the BIOS ( basic system I/O). To do this, after the initial survey of hardware and sound signal POST, press F10 or Delete, depending on BIOS versions, and open the menu items one by one. If the keyboard does not work, then the problem is technical.
If you have a mouse and keyboard with ps/2 connectors (small round 6-pin ones), make sure you don't mix up the mouse and keyboard ports when connecting. They are marked with the color or images of these devices. Make sure the pins in the connectors are not bent or broken. Test your mouse and keyboard on another computer.
Connect devices to the ps/2 connectors only when the power is off, otherwise short circuit can disable the port.
The southbridge may be overheating motherboard. Remove the side panel system block and find 2 large chips on the motherboard. Carefully try the bottom one. If the chip is too hot, it makes sense to contact a computer service.
Remove the round battery from the socket on the motherboard that powers the ROM chip. Use a screwdriver to bridge the electrodes in the connector for a few seconds to reset the BIOS settings to factory settings. This will help if you unsuccessfully changed something in Setup.
Operating system errors
The mouse and keyboard may freeze due to malware. Download from the DrWeb or AVP sites a LiveCD image with installed antivirus programs and burn it to a CD. In the BIOS, set the boot order from the CD or DVD drive and boot the computer from the disc. Check the system with an antivirus.
If the mouse and keyboard freeze when booting from the LiveCD, the problem is either with those devices or with the motherboard.
The reason for blocking may be incorrect installed drivers or other programs. Turn on the computer and press F8 after the POST signal to bring up the options menu Windows boot. If you have Windows 8 installed, use the Shift+F8 keys to bring up the menu. Select "Safe Mode". If in safe mode devices respond to your actions, remove the recently installed software.
Press Win and in the "Programs" section, select "Accessories", then "System Tools" and "System Restore". Following the instructions in the recovery wizard, depending on Windows versions, specify the next date the checkpoint was created.
Good afternoon!
There was a following problem and I will be grateful for the help.
Keyboard - USB and Mouse - PC/2 freeze after an indefinite time (it can be after 2 minutes and after 10 minutes) after starting the computer. The only way out is through Peset. During operation, the mouse behaves, as it were, irrelevant, i.e. it is necessary to repeat the task several times. The computer itself, when booting, behaves normally, without reporting any errors.
1. My first suspicion fell on a virus. Dr.Web anti-virus checked HDD and all additional media (USB-Stick and external hard drive) and viruses were indeed detected. I didn’t really succeed in removing them, as there was a periodic freeze. And in order to leave no room for viruses and doubts, I formatted the hard drive, installed Windows XP SP3 and more recent drivers (Windows licensed, drivers from Nividia, Realtek offsite sites) But the problem remained. color=red>
2. I checked the temperature with the EVEREST program, the temperature does not exceed 45 gr. in all organs. The processor was cleaned by me a little less than a year ago, the video card has been cleaned of dust now. See also all modules random access memory, just in case something went sour there. But the problem remained. color=red>.
3. Just in case, I checked the operation of the power supply by removing it from a healthy computer and also another hard drive. But the problem remained. color=red>.
4. I checked the capacitors on the motherboard, lighting each with a flashlight. Didn't notice any negatives.
5. Wire connections are not loose.
6. HBCD 10.4 from boot floppy checked for errors. There are no errors. BUT color=blue> RAM can be checked by various methods offered in this disk and all checks do not reveal errors. But when choosing functions -Windows Membery Test, something like this picture "" ___________________- color \u003d red> appears on the screen. And the computer freezes. Those. verification is not carried out.
I also noticed that the frequency of freezing increases with each new overload. And yet, when working in protected mode, there were no freezes, except for the last single case when the mouse did not react, and the keyboard was alive.
Anyway, I hope I haven't missed anything.

The mouse is an integral part of any computer system and since 1981, it has become the main tool for interacting with the operating system.
Therefore, it is not surprising when a mouse in a computer or laptop freezes and does not respond to anything, no matter how long: it freezes for a second, for a few seconds, periodically or constantly, it infuriates.
Unfortunately, such a problem exists and practically does not depend on the OS, whether it is windows xp, windows 7 or windows 10, especially if it is a wireless mouse.
Most often, the mouse cursor slows down and freezes due to its own fault. Why? Because consumers, as a rule, are guided by two criteria - price and wired or wireless.
It is not right. The choice of a mouse is even more important than the choice of a keyboard, and it is not easy to choose it, since there are a huge number of different types, shapes and models flooded the market.
In this entry, I will partially touch on the choice, since after reading this guide you may need to buy a new one.
The main part will relate to the topic of the article - why a wireless mouse often or sometimes freezes in a computer or laptop.
Note: not everyone knows, but now there is a way to use the keyboard without a mouse -
What is the difference between computer mice
There are two main types - optical and laser. Both technologies are very similar. Both use a beam of light that bounces off the surface and informs the computer of the position of the mouse.
Laser technology allows for much more precise interaction, which is why it is the choice of gamers and other users who need precise cursor control.
Laser also allow you to get a higher DPI, which is especially important for gamers.
For the average user, dpi above 1000 is more than enough, and there are practically only such models on the market.
The advantage of optical technology is that it is simply cheaper. Even in the case of gaming models, the models are very similar to each other, differing only in the sensor and strongly in price.
If you want to work with the mouse on almost any surface, you should look at with a laser sensor.
It will not work only on a sheet of glass or other transparent surfaces, although there are exceptions, for example, the Logitech Performance Mouse MX is equipped with Laser Tracking technology, which allows it to be used on glass (with a thickness of 4 mm above), since the laser is so accurate, which can reflect the beam of microscopic glass imperfections.
An alternative to optical and laser sensors is provided by Microsoft with BlueTrack technology, using a wide beam of blue light.
It can work on any surface (except glass and mirror surfaces) while maintaining accuracy. Although she doesn't The best decision for hardcore gamers, but office users will feel the difference in technology.
How I fixed the problem with the constant freezing of the wireless mouse
I was irritated to the point of rage by the fact that my mouse constantly began to freeze for several seconds - in the center of the monitor, in the upper left corner, in a word, it happened everywhere - it hung and did not move.
I repeat, it started to freeze, it used to work fine, only I used it in a laptop.
I analyzed the situation, the only thing I noticed the difference was that when I was connected to the laptop I was next to it, and in the computer the distance increased to at least 1 meter and there were 2 obstacles in the way in the form of a bedside table wall and a computer desk.
Then I bought a USB extension cable, as in the picture below, I connected the dongle to it and placed it not far from the mouse.
The miracle happened, the freezes stopped, the nerves calmed down, the work returned to normal, in a word, the mouse hung due to poor pairing.
The first reason why a computer mouse freezes is a weak sensor
If you have problems with a computer mouse freezing - not always responding to a key press, or a change in position, then the first thing you should check is the sensor.
The optical sensor reacts to objects that send a beam of light - that's why there is movement and responsiveness of the cursor, which changes position on the screen.
Keep in mind that it should not be placed directly on glass or slippery surfaces.
In addition, it is worth cleaning the sensor, wheels and keys (you will need to disassemble) - a can of compressed air and a toothpick are ideal for this.
The second reason why a computer mouse freezes is drivers
Problems associated with the operation of a computer mouse can also be caused by a driver installed on your computer or laptop.
To uninstall and reinstall the pointing device driver, open Device Manager and look for the mouse and other pointing devices section.
Then select the HID compliant mouse, and RMB select the "Uninstall" option. After this procedure, restart your computer - the system will automatically install the default driver.
The third reason why a computer mouse freezes is USB ports.
The problem can also lead USB ports connected to the motherboard. If you have not been able to solve the problem of computer mouse freezes so far, you should check if the device is damaged.
The easiest way would be to connect the mouse to another computer. So you can be sure that the problem is not with the device, but the cause should be looked for in the computer.
Also, you can check computer mouse in safe mode - to do this at boot, press the F8 key and select the menu item Safe Mode.
If it turns out that the mouse works properly in safe mode, then the reason is probably in the system settings.
If the mouse is connected to the USB port on the front of the computer, try connecting it to the rear USB port. That's all. Good luck.
Both beginners and professional users of computer systems can sometimes encounter the fact that the computer stops responding to the mouse and keyboard. Unfortunately, no one is immune from this. It doesn't matter if you work with desktop computer or with a laptop if external type devices are used. Further, it is proposed to consider several main reasons for such an impartial phenomenon and several methods for correcting the current situation.
Why is the computer not responding to the mouse and keyboard?
Speaking about the reasons, perhaps it is worth starting with the worst. For now, let's leave aside the problems associated with one of the devices, and focus on cases where the computer does not respond to both the mouse and the keyboard. Most often, this problem can be observed on laptops. Most technicians claim that this is due to a failure or malfunction. south bridge. It is in this case that all equipment can work, just except for the manipulator and keyboard. However, this is, so to speak, a special case.
As for other, no less common situations, most often the problem is associated with equipment failure, although even completely banal cases can be found. So, for example, if the computer stopped responding to a USB-type mouse, this does not mean at all that the manipulator is out of order.
It may very well be that the power button on the device itself is disabled or the batteries have become unusable.
The computer does not respond to the mouse: troubleshooting options
As for the problems with manipulators, when PS / 2 standard devices are used, connected to stationary computer blocks through special connectors on the motherboard, damage to the connectors themselves is not excluded. Quite often, you can also encounter problems associated with the effects of viruses or driver crashes.
At least on various Internet forums, messages are often published stating that when the operating system starts, the computer does not respond to the mouse, but after putting it into sleep mode from the keyboard and then exiting it, everything falls into place and the manipulator works like nothing happened. Apparently, there is a problem with the drivers.
Finally, it is rare, but it is possible to meet situations when software installed by the user becomes the reason for the failure of the mouse, although it is not known for certain why such a conflict occurs. But the fact remains. If the computer does not respond to the mouse button or wheel actions, there is either a mechanical problem or an incorrect setting in the operating system. As already clear, you should check both the mouse and the settings for buttons or scrolling.
Restart and reconnect devices
So, now let's move on from considering the causes of failures to options for eliminating them. For cases with a malfunction of the keyboard on laptops, you can suggest disassembling it (remove all the buttons), and then thoroughly clean it or wipe it with a damp cloth. Just there a lot of dust and dirt can accumulate. And if you consider that many young people like to work on a laptop, while still chewing on a sandwich, you yourself understand ...
In the case of the manipulator, when it does not respond to the mouse either, you can suggest that the first thing to do is simply reboot the system. If this does not help, you can try to reconnect the device.
For USB sticks, you can use the so-called hot reconnect in a running system. Just try plugging the mouse into a different port. However, PS/2 devices need to be turned on again only when the power is off. If the effect is zero, test the mouse on another terminal, and for your own, try connecting a known working device to find out if there are any problems with the connector or port itself.
Driver Issues
You can often observe problems with drivers, even though you do not need to install any special drivers for the most common devices (not counting specialized game controllers) of any standard. However, as an option, you can perform some steps to reinstall them.
To do this, simply enter the "Device Manager", remove the installed manipulator from the list and reboot the system. When restarting, it will automatically detect the connected mouse and install the drivers again.
Many may object to calling the Device Manager itself. Use your keyboard for this. First, call the Run console (Win + R), then enter the command devmgmt.msc, and in the Manager that appears, navigate using the tab, arrow, delete, and enter buttons.
Recently Installed Software
As for the software that could cause such conflicts, in the programs and components section, just check which applications you installed in recent times, and just before the occurrence of failures.
If necessary, simply uninstall the selected software, just in case, reboot the system and check how the mouse will behave.
Reverting the system to a healthy state
In principle, if there is a problem that the computer does not respond to the mouse, sometimes all the above steps with drivers or reboot can be omitted. As practice shows, in most cases, if the problems are related specifically to software failures, it is best to use the system rollback to the time point that preceded their appearance.
In this case, you can use the corresponding section in the "Control Panel", which is called up through the "Run" menu with the control command, or perform several forced reboot computer system by long pressing and holding the power button. The method, of course, is barbaric, but sometimes it can still be used. When you start recovery, you will simply need to follow the instructions of the "Wizard", and if necessary, select checkpoint rollback from the extended list yourself.
Virus check
Finally, it is believed that the appearance of problems associated with the fact that the computer does not respond to the mouse, is particularly affected by computer viruses. Not all, of course, but some specific threats are really capable of causing such failures. The solution to fixing problems is obvious: the system should be checked for the presence of such threats, and if identified, they should be neutralized.
But what tools to scan? It is clear that in this case it is not necessary to rely on the standard antivirus installed in the system, since it has already missed the threat. In this case, portable type software is considered the most relevant. Most often, programs like KVRT, Dr. Web CureIt! and the like, but only with a mandatory update anti-virus databases before launch. And you need to choose to check not only the hard drive (system or logical partitions), but also all hidden or boot areas.
But the most powerful tool of our time, no matter what anyone says, are utilities with the general name Rescue Disk, which have their own bootloader, with which you can boot from removable storage media and perform a deep scan of the computer system and RAM even before activating the start of the existing on the operating system computer, which significantly increases the chances of detecting and neutralizing threats. By the way, it is these utilities that find and neutralize almost all viruses known today.
Instead of total
That's it in a nutshell, and that's all there is to troubleshooting issues with mousepads and keyboards. It remains to be said that only single situations were considered here, and in fact several factors can simultaneously influence the appearance of problems. So in this case, you will have to consistently find out the causes of failures and only after that choose the preferred means of correcting the situation.
