Are all these programs still on your computer? This also could give conflicts. If you have been installing- and uninstalling various programs with same goal your registry might be "polluted "with all sorts of " stuff "
First of all
Download install and update Ccleaner
After installing and updating go to options - advanced and tick prompt for registry back ups
Now Start up in safe mode
Do two runs
