Virtual Memory has to do with memory from your harddrive that your computer treats like RAM. How much RAM do you have? (Right Click on My Computer and select Properties...it should be found on the general tab) The minimum requirement for an XP system is 128 MB of RAM. If you have this amount (or less) then you are probably running too many applications at once. The more applications that you run at once the more RAM that is required. Once you are using all of your RAM the computer starts using a reserved part of your hard drive as if it were RAM. This is called Virtual Memory.
To see the amount of Virtual Memory that you have reserved, right click on My Computer and select Properties. Select the "advanced" tab and click the Performance->Settings button. Select the "advanced" tab. There should be a box titled "Virtual Memory".
Pagefile (Virtual Memory) -- Rght click MY Computer - select propeties - Advanced tab - Performance - advanced tab - Virtual memory click change, you can put the page file on a differnt drive (if you have one), click custom size and set Initial size to one and a half times the amount of memory you have fitted i.e. 512MB memory = set to 768MB, set maximum to double your memory amount i.e. 512MB memory = 1024MB click ok. If your hard drive is full and there is not enough room for the pagefile this can slow down, freeze or even cause the PC to crash (restart).
Thanks for all the replies and will read them all, I have an 80gb hard drive of which about 60 is free, and I recently increased the ram from 512 to 1024, thank you again, I hope I can understand some of your answers.
