Hello and Welcome to Free PC Help Evil.
You have a lot of processes running. For one, your CPU usage is full which is bound to cause lags processing other tasks. As Tootech says, try ending the processes or better yet uninstall the programs using them.
We can start by looking what is installed on your computer.
1. Download and install CCleaner (Slim) from
here.
2. After the installation is complete, run the application by running clicking on the shortcut on the desktop. Click on the
Tools tab.
3. It will present you with a list of softwares installed on your computer. Press the button that reads
Save to text file.... It will ask you for a location to save the file to, so save it to a convenient location (preferable on
Desktop).
4. Browse to the location where you saved the file and open it. Copy and paste its contents in your next reply.
And while you are at it, please use CCleaner to clear old cache and temporary internet files. It will help you recover some of your disk space, if not give a tremendous performance boost. Provide us with the required information as soon as possible.
Note: Do not use CCleaner's registry cleaning feature unless specifically advised so. It may cause more harm than good if used carelessly.
