Keyboard Problems on my Dell Inspiron 6400,

Click the Windows "Start" button or press the "Windows" key. The "Start" menu opens. Type "Cursor blink" in the "Search programs and file" text box. A list opens. Click "Change Cursor Blink Rate." The "Keyboard Properties" window opens. Click the "Speed" tab. A list of options appears. The "Cursor Blink Rate" section shows a "Cursor Blink Rate" slider displaying a range from "None" to "Fast." Click and drag the slider button to the "None" area in the far left portion of the "Cursor Blink Rate" scale. Click "Apply." Click "OK." The cursor stops flickering on the screen.

Try redownloading the driver for the mouse and see if that fixes the problem.

What type of keyboard you are using (PS/2 or USB)? Is that a regular keyboard or multimedia keyboard? You need to isolate the problem. Please follow the steps below.

If you are using a USB keyboard:

1. Connect the keyboard into different USB ports of the computer.
2. Connect the keyboard into different computer.
3. Try using different keyboard to see if the problem will persist.


If that is a wireless keyboard:

1. Try replacing the battery
2. Connect the receiver into different USB ports.

Check the keyboard settings:

1. Go to the Control Panel > Keyboard
2. Adjust the keyboard settings and speed.

Hope it helps and have a great day!
