The problem is any key I press I get weird thing happening like four or five letter show up on one stroke ( I do not type that fast) and it start piping immediately ( same sound like the keyboard is faulty} and then all kind a windows start popping up and I can stop it only hard reboot, but soon I touch any key same thin happens again. I have already tried another keyboard same result. Open the laptop and look for a spill, but there is none. Clean the ribbon plug and surrounding area with Flux Clean and after putting the laptop together it actually worked for a week with no problems at all, but now the problem is back same as before.

Could there be chip with a cold solder I maybe disturbed with the cleaning and it worked for that short time?

Yes, the problem could also be reduced to a bad motherboard
