is resident on your hard drive as the 'page file'. Using your systems "help" learn how to increase the page file size. The standard is 1.5 times the amount of physical memory on your system. If it's already set that way then you can increase it to 2 - 2.5 times. If this doesn't fix your problem then something else is amiss.
Make sure you don't have any unnecessary programs running in background. Delete all your temp files. When was the last time you ran your anti-malware prgrams? Let us know.

I have a four year old emachines t3092 amd 3000+ 160gb hard drive... If I am on for any length of time I the pc gets slower and slower and then eventually a error message saying my virutal memory is low.. What can I do to correct this? I have never done any upgrades on this machine
