My windows XP SP3 Dell laptop has a problem that has been getting worse over time. When doing normal things like switching programs, or opening windows, or opening or dragging files, or right clicking on an item in a program - all normal things - it will get stuck for 15-30 seconds and the hard drive will be 100% busy. I have more than enough RAM (4GB) and am letting windows set the Virtual RAM. A year ago this problem did not exist - I have not changed any hardware since then, and this problem has slowly become more common until now - it will do it's 15-30sec freeze thing about once every 2-3 minutes. It's maddening. I am ready to pull my hair out. Any ideas would be fantastic.
