HP Compaq Presario — keeps typing 5 automatically

Address:

Raigad, Maharashtra

the system has developed some problem. it keeps typing number '5' automatically. to stop this i have to type 5. this problem arises too often and hinders my usual work. this happens whene5ver cursor is placed in a typing space. once it is stopped, it re occurs any time after that. u may have noticed the word whenever on the second 55l5i55n55e5555555. 55555555555555555555555555555555555555555555555555555555555555555555555555555555...⇄ see now u can see... i pressed the number 5 and so it stopped automatic typing...

kindly solve this....
