I check my computer property performance and it shows that "virtual memory" is disabled.
Whether I check "Let Windows..." or "customize", when I restart the computer it still displays "virtual memory" is disabled (as it would be "customized" but can't reinstate it).

Now what

Windows 98SE, 1024mb RAM, 88% free on 120gb HD "C"
(also have space on 2nd 80gb HD "D" but OS is on "C")
