Why does my computer keep freezing up then takes a few minutes to catch up?
Maintain Your Computer. Disk cleanup and defrag is the fastest and easiest way to speed up your computer. It’s also a good idea to check what you have running in your startup programs. Many programs may launch on startup through default settings when you install an application. Over time these applications add up and they may be draining your system resources. To see what programs are currently running on start-up, in Windows XP or Vista click on Start, select Run, then type MSCONFIG and hit the Enter key. Select the Startup tab from the dialog box. Here you can deselect any items that are running that you don’t actually need when you first start your computer up. Select Apply after deselecting the startup applications and reboot the system to check for noticeable speed gain when it restarts again.
