Weird Lag

[GM-Pandora]

Make sure you have a good amount of free space on your computer, when the computer is running low on memory it will take hard drive space and convert it into virtual memory.

It may sound silly but keep your desktop clean also, you can have folder and shortcut on it, but avoid big files or many files, put them in a subfolder.

Run a spyware check.

If none of that seems to help, try to think of what changed on your computer since this started happening, any new software that you installed?

As last resort, try to contact your ISP.
