This is gonna be difficult to explain, but here goes: I'm running Win/XP SP2 and lately I've noticed that my pc "stalls" at times, for a few seconds, when I bring up a directory with Windows Explorer or other program, like when I go to MyDocuments - it takes maybe 30 seconds for the screen to actually display the files/folders in MyDocuments. I don't think it's actually a problem with Windows Explorer, because I have the same problem when other programs do a file list - the computer just 'stalls' for anywhere from 15-60 seconds and then takes off, listing the files/folders. Once I've displayed a directory, I can go back and re-display it and it pops right up. But if I wait an hour or so and go back to the directory, I'll usually get the pause. I've noticed that my wife's pc does this to some degree, so maybe it's not all that unusual - I've disabled indexing to see if that was causing the problem, but apparently not. I use AVG Internet Security, btw. Would more memory help? (I have 1mb now). I'm using an SATA drive and I've used Sandra to test virtually everything about the system, with all results in the "acceptable" range for the hardware type. The system isn't crashing, but this is really annoying. Any ideas what might be causing this?
