I've been having this problem for some time on this new computer. I think it might be some malfunctioning device driver, but I really don't know where to begin looking. Sometimes when I am using networked applications (including one I am currently writing in C#), opening a dialog box will cause a 3 or 4 second delay between when I click it and when my system finally is able to respond. After this time, it finally shows up in the task bar; during that time, my system is completely unresponsive to everything else. This can also happen, on occasion, if I click a link in a networked application and it tries to open in the default browser (which is already open and waiting). I should also clarify that it's not just dialog boxes, but can also be new windows from an application (for example, Windows Live Messenger). I'll be working away and suddenly my computer won't respond for 4 seconds. Then, after that time, a new IM window will pop up on my task bar with a new conversation someone started, and then I will get control of my OS back again.
I've actually just gotten used to it over the last year or so, but now it's actually causing problems with the application I'm building (even trying to open an "Open File" dialog box can cause the system to miss key messages sent from other connected users during this stall time). I know this isn't supposed to be this way. Do I have some sort of malicious program causing this? Is it a bad driver or something to do with Windows? I would prefer not to have to reinstall Windows if I can; I'm unable to deal with that big of an overhaul of my PC at the moment.
Thanks for any help! I will be willing to post output logs from certain programs if someone thinks they will be helpful. I chose this forum because I think it is related to the operating system, but if someone feels it's better served elsewhere, please move this post!
