The problem with the computer itself, definitely not the keyboard problem, if you don t understand,

2. If you can use it, re-establish the mapping of computer keys, select "Keymapper" or KeyTweak (required**). If that doesn't work, you can map the keys you don't use.

Software introduction attached:

1. Huacai Alliance Keyboard Diagnostic, this program can obtain the attribute value of your keyboard, as well as return the key value of any key on the keyboard, and can test whether there is a problem with your keyboard keys.

2. KeyTweak maps a key to another key by setting the system's registry, and the software provides a special function key that is not available on your keyboard (such as special keys on some notebook keyboards and some multi-function keyboards), so that ordinary keyboards can become multi-function keyboards, multi-function keyboards - > super multi-function keyboards, and you can enjoy more powerful keyboards without spending any money.

Of course, it can also be used for other things, such as: no longer have to worry about the frustration of pressing the win key by mistake when playing Warcraft or CS, and some broken keys can be redefined to other buttons, etc.

Hope this way solves your problem, good luck.

It is not excluded that it is a virus.

Check the control panel to see if the double-click speed of the mouse is set too fast.

Many viruses, such as vikin, falling snow, will automatically generate a file on the hard disk, even if the system is reinstalled, this damn file will still exist, the manifestation is that the hard disk can not be opened by double-clicking, and it needs to be opened.

Solution 1.

Open My Computer - Tools - Folder Options - View.

Hide the system and cancel the two attributes of hiding files, and then open the hard disk, and you can see the files. Then delete it completely, reboot the computer, and you're good to go.

Solution 2.

Run cmd to open the command prompt window.

Convert to a D drive, or a drive letter for a disk that needs to be opened.

Type dir a and you should see this file.

Then type attrib -s -h -r, this command means cancel the file read-only, the system read-only, and hide the attributes.

Then type del to delete the file.

Or open the hard drive partition and manually delete the file. The other partitions will run in this way in turn, and you're good to go.

Now your situation is to enter the safe mode to see the antivirus, or change the keyboard to enter the system antivirus.

Try a different keyboard, if it doesn't work, it may be that your motherboard is broken.
