virtual memory!!!

i have a pc (p4 1.6ghz, 256mb ram and 40gb hdd) just freshly install to windows 98 with lotus smart suite v9.6, lotus notes r5, norton antivirus corperate edition v7.6 and some ms. office viewer program.

The problem is that i cant run scandisk/defrag in windows mode even in safe mode. I kept running into the this error message telling me that my system doesnt have enough memory to perform that operation and ask me to quite some program to free some memory.
