Welcome to the CH forums.
This is not an instant help system so any help will come to you sometime.
Turn OFF caps and bold - not required, they won't speed answers to your query in any way.
We cannot see your pc, don't know if its a laptop or desktop or what Operating System you are running, could be anything from Win.3 thru Win.Vista.Premium - so how about some info to help us help you to get anything like a correct diagnosis.
We'll need names for the "certain softwares" you are trying to open, your operating system etc.
