ok i went to install a game on the computer...so i put the disk in and it doesnt work and my computer freezes up! so i shut it down and when i turned it back on it said that the computer is low on virtual memory and doesnt have a paging file. so i go into system on the control panel, then to performance and the place where i can adjust the paging file. everytime i input any number besides 0 it says that its too big. what!?!? i've only tried this in safe mode because when im in normal mode i cant click on anything because it says there is not enough memory to run the program? also, i cant install norton antivirus on my computer. whenever i try it always reaches like 99% when its installing but than at the last minute it says that it didnt install and that there was an error. sorry im not really good with computers and if im not clear enough here i'll try again, but does anyone know how to solve any of this? or at least direct to someone who can? by the way, i have a Dell with windows xp on it.
