I am running windows 8.1 64 bit but I see all ,my programs are 32 bit, I do not understand that/ Could that be the reason it is so slow and unresponsive at times? I have tried everything possible but cannot figure it out or resolve the problem.

Most programs designed for the 32-bit version of Windows do work on the 64-bit version of Windows. Device drivers designed for the 32-bit version of Windows don't work on computers running a 64-bit version of  Windows.

By the way how much memory is there? You haven't mentioned  hardware specs.

I shall suggest you to scan your system with latest version of anti malware tool to make sure that the system is clean.

You may also try to Clean Boot

Fragmentation makes your hard disk do extra work that can slow down your computer. Disk Defragmenter rearranges fragmented data so your hard disk can work more efficiently (no need Disk Defragmenter if you are running a SSD)

Run Disk Cleanup-removes temporary files, empties the Recycle Bin, and removes a variety of system files and other items that you no longer need.

In order to diagnose your problem we need to run Windows performance toolkit the instructions for which can be found in this wiki If you have any questions feel free to ask
