If I leave my PC on for longer than about 6-8 hours my windows 7 starts creating more explorer.exe's. So when I open the task manager and look at running tasks there are about 10-12 explorer.exe tasks running. Also when this happens if i right click to open the drop down menu of a folder or desktop or basically anything explorer.exe crashes. So I must repeat the process 4-5 times till eventually explorer.exe doesn't crash and the drop down menu appears. It also consumes a lot of resources having all these explorers open. I have used the same dvd to install windows 7 on 2 other pc's and neither of them have come across the same issue that I am having. Does anyone know why this could be happening.
