The Windows networking components have a timer at 600 seconds or 10 minutes.
http://support.microsoft.com/kb/297684 notes this KeepConn entry and how to change it's timing. What you need to know is this can happen on machines that have a share connected and the share is offline. Fix? Bring that share online or just right click on Network Neighbor and disconnect from all shares.
I've been having a little annoying problem with my PC for a while now. The whole thing is only a little over a year old, and this has been happening for at least 6 months. I was just thinking that it's about time to do something about it because it's really getting on my nerves and slowing me down.
Periodically (10 times an hour maybe) while I'm using my PC, it will just completely freeze up for around 10 seconds. It will start making a progressively louder whirring noise that sounds kind of like a plane taking off, then it will click and everything will be back to normal.
It seems to do it more often when I'm working with files, like moving them, opening the "save as" box....
It seems like the issue is probably the hard drive, but I wanted to run it by you all. I think it's the hard drive because there's obviously a moving part that stops, clicks and starts again (not sure about the whirring).
What do you think? Would appreciate any suggestions, as my PC is likely to "take off" out the window by my desk shortly if I don't fix this lol.
