Hi, I run Windows 7 Home Premium x64.
Here are my system specifications.
ATI RADEON HD 5750
There's something going on with the following applications:
Windows Media Player
Windows Photo Viewer
ATI Catalyst Control Center.
They are slow to open, slow to close. When trying to select or click buttons, it's highly laggy.
On the other hand, Google Chrome, Microsoft Office applications like Excel, Powerpoint and Word are fine. Games run smoothly and load fast too!
I've tried scanning and fixing with both Avira and Advanced System Care to no avail.
