Hi. A few weeks ago, I upgraded my RAM from 1x128 to 3x256 MB. Indeed it does make things run smoother, but I already twice got a problem with Norton AniVirus. With only a few browser windows open and a Java application, (and on a freshly reinstalled W98SE) I hear the display click, get a black screen, then blue, not the Windows BSOD but this time it's from NAV: "Warning. System Memory is running very low. Norton Anti Virus may not be able to function properly. Click any key to continue." And then I could return to Windows, but the Java chart wouldn't load. (Prophet Charts it was) How can this happen? I never had this with my 128 MB, and now with 6 times that much, it's running low on memory??? The memory I bought is A-brand (Infineon). I know there are RAM managing programs, but I think it just shouldn't happen. I wasn't using a RAM manager as I hadn't reinstallled it yet. After inserting the RAM banks I ran the memory diagnostics test that came with my computer: everything was OK Anybody any idea what may be the problem?
