Anonymous users2024-02-07There are two possibilities, first: the keyboard is broken, it turns out that other people have also had this situation, and then the keyboard is suddenly better.
Second: virus, but it's unlikely, because you reinstalled the system, I guess you have a problem with the keyboard.
See if that's the problem.
Depending on the phenomenon of auto-mute and the files it generates, we can go into safe mode to remove mute viruses.
The first step is to enter the safe mode (press the F8 key when the computer is turned on). Open my computer and delete the C drive and temp.
iexp1ore (note: non-iexplore, Nakami is not l, it is 1 of 123, and the files in the system are l), delete the searched files together! Go ahead and search for a few files below:
lgsyzr, o2flash, and the processing results are the same as above!
Step 3: Enter the registry (enter regedit in the run): press F3 to find the following items: LGSYZR, O2flash, Alga, iExp1ore, iExplora, ServiceA will delete all the value items searched for.
Step 4: Start-Run. Enter msconfig. Banned alga and iexp1ore in the startup items! Restart your computer. Then go to the system and delete the alga file (search is OK, so hurry up).

Anonymous users2024-02-05From a general point of view, the newer CPUs and graphics cards have the function of automatic energy-saving mute, that is to say, the main frequency is automatically reduced when idle, at this time, the power is small, the heat is small, the fan speed is slow, and the sound is naturally silent. When running a relatively large program, it will run at full power, the heat is large, and the fan speed will automatically increase, and the noise will be loud at this time. The CPU of i5 and i7 also has a turbo frequency function, when running a large program, it will be automatically overclocked, and the fan speed will be automatically increased, making it louder.
This mechanism can be manually switched off and then operated at full capacity, i.e. non-silent. Or when you manually overclock your CPU or graphics card, you will also lose the ability to automatically downclock. However, home users do not recommend closing the cavity belt, and after closing, it loses the meaning of energy-saving mute.
If you are more detailed, some manufacturers' socks banquet motherboards have a more user-friendly design than Wu Haolu, with 3 preset modes, mute, balance, and performance. You can read the manual of the motherboard and set it up yourself according to your needs.
The small horn in the lower right corner, with a small fork, is muted, and the left button and then click the horn or pull the progress bar to have a sound. >>>More
You used to use the administrator account, but then because you opened another account, the administrator account will not be displayed when the computer is turned on by default. You need to press F8 to enter the safe mode when you boot up, log in with the administrator account, delete the account you created later in the management, and only keep the administrator account, and the default is the administrator when you log in normally.
It's not that simple, if you want to change it, you have to check how the original sound card and all the connection ports of the motherboard are, (if it's an integrated sound card, it's troublesome, but I haven't heard of a sound card with an integrated one.) Then confirm whether the sound card you want to replace is compatible with the motherboard, whether there is a problem with each interface, if there is no problem, you can start the replacement, but you must be careful. After replacement, you can start using it, and the headphone port can of course be used, as long as there is no wrong connection.
