I started my computer one day and before my desktop appears a box comes up saying my page file is too small, and more space needs to be added.  I right clicked My Computer and the Advanced tab and Performance options, Change, and now have my initial page size at 600MB and max at 1000.  I still get these messages each time I start up no matter how much I raise it.

How much free hard drive space do you have?

Also, what version of windows and what are the specs of your computer?
