Binita,
Welcome to the HP Community Forum.
Could be almost anything:
A program might running 'round in circles and slowing eating up all your memory is one guess.
Your system could be in need of maintenance -- the disk might be badly fragmented:  Your files might be spread all over the place -- and in pieces -- and far away from each other.  This is relative, of course.  The "far away" is tiny distances and the amount of time it takes your computer to gather data is tiny amounts of time -- but it can add up to big delays after awhile -- delays that you notice.
Your computer might just have too many junk files that are "getting in the way" of a clean operation.
Your computer might have little bitty mistakes in the File System that are making it hard for the computer to perform its tasks.  Tech speak for File System Errors.
It could be a network problem, although this is something you will have to track.  The fact that the issue starts after you have been on the system for awhile means you need to know what you are doing during the slow-down to have an idea what you are looking for.  The Task Manager can give you an idea whether the Network traffic is heavy and the Performance Monitor can help track traffic hogs.
Could be your Internet Service Provider dragging down your service -- this is harder to track, this is outside of the purview of this forum, and this is not an HP problem although you will find lots of people swearing that ISP issues come back to the computer being the culprit.  If you are streaming, gaming, or using the system for anything that your ISP dislikes, it may put a choke on your service after a specified time.
Could be malware -- This is a different arena and you need to look to your Security Software to see if there are issues there.  Run a deep scan to be sure the system is clean.
You might take a look at the following and follow at least some of the suggestions:
