That's probably a defective hardware problem.

If you're using a corded or wireless mouse, it's common for the wires inside the cable to get damaged, for the corded mouse or the transmitter/receiver for the wireless mouse, usually right near where they enter the mouse or transmitter/receiver - try another one.

If you're using the touchpad, you may have to replace it.

However....

- have you dropped the laptop, or have you spilled any liquid on the laptop, or exposed it to liquid (e.g. rain) since the touchpad mouse last worked properly? It doesn't matter whether it was running at the time or not.

- if you have just cleaned it, I have found some touchpads behave weirdly for a while after they have been cleaned, especially likely if you use isopropyl alcohol, or something containing that. Some behave weirdly when you merely get them wet. They continue to behave weirdly long after they appear to be dry, because the liquid has been absorbed into the touchpad, and/or into the chip(s) underneath it that control it. In that case, it will probably be okay the next day, but it's advisable to NOT use the laptop till then.

"... my cursor moves continously as if the tab key is being pressed... not jumping but running to the right side... sometimes fast then it sometimes slow down.sometimes it cease... but sometimes very fast that the page of my screen goes up and down... "

I forgot to mention your keyboard can cause your problem.
Check to make sure all keys are all the way up - not stuck down or part way down - that's quite common on laptops.
I've had your problem happen on old keyboards that developedstuck keys, and on corded keybosrds that had damaged wires inside the cord.

The keyboards on laptops are not as robust as most ones for desktops are. After they have been used a lot, it's common for the most used keys to not always work properly or even to stop working.
Laptop keyboards are a frequently replaced item, and can be quite inexpensive to buy.

You could try a PS/2 or USB connected keyboard, but the cursor may still move if you can't disable the onboard keyboard in any settings - see the User's or Owner's manual for your model. Sometimes people have no choice but to unplug the built in keyboard and use an external one, until they get a replacement keyboard. Sometimes you have to open the case to do that, sometimes you can do it without having to do that - see the User's or Owner's manual for your model, however, that info may be only found in the service manual, or possibly on the web.
HP and Compaq usually have servce manual downloads, but most other brands do not.
.......

Do you normally use the touchpad, or the corded mouse? A lot of people hate their touchpad and would rather use a corded or wireless one, most of the time.
If you don't use the touchpad much it's probably okay.

If you have another corded mouse to try, try that, however Windows allows you to have more than one mouse connected if they're connected different ways (the touchpad is often PS/2 connected internally), and may even allow more than one USB connected one, any one of which can be used at a time and affect the cursor, so the cursor will still move, if it moves with the corded mouse you have now disconnected.

It sounds like it's likely the keyboard that's defective.

As I said above...

See if you can disble the "... onboard keyboard in any settings - see the User's or Owner's manual for your model. Sometimes people have no choice but to unplug the built in keyboard and use an external one, until they get a replacement keyboard. Sometimes you have to open the case to do that, sometimes you can do it without having to do that" (open up the case) " - see the User's or Owner's manual for your model, however, that info may be only found in the service manual, or possibly on the web.
HP and Compaq usually have service manual downloads, but most other brands do not.
