You need more physical ram. Or to run fewer apps at one time. Windows is supposed to adjust the virtual RAM based on need. It uses hard drive space. When it run low on physical ram it needs to use more hard drive space.

I agree with above, you should have at least 512MB of RAM, more if you can manage.

A trick that some tweakers use is to figure how much virtual ram they are likely to need and then set it as the max and min, but unless you know specifically I'd probably just let Windows keep managing it.
