There are numerous threads on how people have come to solve their individual "explorer.exe hogging system resources" problem, but I'd like to know if there's a more straightforward way to solve the problem than "Oh, I remember such and such file, I'm going to delete it." I can essentially inflict the system resource hogging by simply randomly clicking on a few files in any random folder in my computer. It causes the system resources to spike up to 70% on task manager, and causes a massive slow-down of my computer. HijackThis, spyware scans, virus scans, scandisk, etc. don't show up anything, so I'm assuming it's just a faulty file accessing error, even if no error messages have popped up. Anyone know of a good diagnostic tool that'll tell me what programs/files are being accessed by explorer.exe? Also, I'm using Windows Vista Home Premium, if that helps.
