System undergoing startup repair without any results

[Gaurav10069]

My system undergoes startup repair everytime i start my computer and after a long process of searching for problems it restarts and the same startup repair problem arises.
It also displays the message "This may be caused due to a recent change in any hardware or software of the system".
I hv infact installed windows 2-3 times since this prblm started bt still this problem arises.
Plz help me out......
