Whenever I close an application there is a 1-1.5 second delay while the computer is not really responsive (mouse moves but doesn't register clicks and keyboard doesn't do anything [doesn't bring up the Start Menu if I press the "Windows Logo" key on the keyboard]).
Some details I thought might help:
- this problem happens with all applications, no matter what
- I've tested the memory, the hard drives, Computer Management, basically everything I could think of
- no BSODs, no freezes (except after I install DAEMON Tools SPTD, then it happens a lot), no Error messages in the Event Viewer
