Computer constantly not responding when opening programs

[cdude8]

Hi, I would really like some help to solve the problem I am having. Whenever I open a program or file, it will almost ALWAYS stop responding for about 5-10 seconds, then work fine for a small amount of time, then go back to not responding again when i click something. This has been happening for about a week now, and I have already ran multiple virus and malware scans on my computer, like Avast Antivirus, MalwareBytes, and Windows Defender. I would really like someone to help me solve this problem, because my PC is just becoming more and more unusable . I have a Windows 8.1 64-bit PC with Intel quad 1.7 Ghz processor and 6 Gb of RAM.

Have you tried and/or looked at any of the following?

Number of programs in Start-Up list
How much memory is in use
Check fragmentation % of your HD
Deleted temp files and/or internet files
Run some basic diagnostics like sfc /scannow

Hi cdude8,

Try uninstalling unnecessary programs:
1. Press Windows + R keyboard buttons.
2. Type appwiz.cpl then hit OK.
3. Uninstall all programs that you do not use.
4. Restart your computer.

Check the Task Manager, press CTRL + SHIFT + ESC, Sort the programs according to Memory size consumption. Take a screenshot and post it here.

You can also try scanning your computer using another antivirus like Trend Micro Internet Security.

I agree, you might have an inordinate number of programs running at Start-Up, Your system should be able to handle a number of these, but at some point, if you have a lot of them they will start to interfere with regular programs. You can use CCleaner or the Task Manager (Under Start-Up) to disable what you don't need. In WIndows 8, there is a "Startup Impact" value listed for each item, remove all items that are listed as "High".
